Soursop full process: From harvest to pulp

Happy to share with you a full transparent process of harvesting the Soursop Fruit (Annona muricata L) to the final frozen pulp. This short article and video will help you to understand the Artisanal Processing of Soursop Pulp. Obviously without the use of ANY additional ingredients, at all. The goal is the keep all of the natural health benefits of the soursop fruit.

As you may know in Ecuador the Soursop is called Guanábana. Our guanábanas grow here at the edge of the amazon basin in Ecuador, where the tropical climate with lots of rain and sun rays produce some of the best, most flavorful soursop fruits in the world! We have been told nothing less by all of the people trying our pulp for the first time. Once you see our entire artisan process you will understand why it has such a delicious taste.

Most of the industrial processing of pulp fruits consists changing the flavor, color, and aroma of the fruits. Logically this removes a lot of the nutrients and health benefits from them. You have to know that within the industrial-pulp-production – it is normally the not so perfect fruit which cannot be sold any more. This is what gets processed into pulp and thus not high quality fruit.

Below you will see a micro video which helps to visualize the different steps on how to make organic soursop pulp.

Soursop Processing

Growing Bamboo From Seed

To grow bamboo from seed, start by soaking the seeds in bowl of water for 12 to 24 hours to help them germinate. Planted fresh bamboo seeds the 31.01.2019. After letting the seeds in a bowl of water for 24 hours, to soak it up. To help germinate. During the first 8 weeks we kept the the soil moist.

Planting bamboo seeds (31.01.2019)

14 Feb 2019 – first germination of bamboo seeds

All-ready 14 days after planting the seeds. Keep in mind we might be in a ideal climate for this. Very high humidity and lots of natural light. Other people around the world have reported it can take longer. Depending on the local climate environment. The first germination was well visible on the cotton method. Most likely the seeds in the soil did germinate too but we where not able to see it because they where in the soil.

17 Feb 2019 – more changes visible

18 Feb 2019 – germination status

18 days germination. First miniature green leafs popping up.

20 Feb 2019 – germination

28 Feb 2019 – bamboo germination status

All-ready 28 days after planting the seeds. As you can see we have tested different methods for the seed germination. From cotton to special germination molds to bucket-taps and tomatoes plastic packaging. All of the method has worked. But the cotton method was not ideal for extraction. The roots of the seedling where very difficult to remove from the cotton and replant into another soil pot. So we do not recommend working with that method should you be interested in germinating bamboo seeds. The best option was with the special germination mold where each seed is place into one of the spaces. Later it can be extracted much easier.

23 days after planting the bamboo seeds

10th March 2019 – bamboo seeds

40 days germination and this is how it looks. As you can see the germination of the seeds worked for about 25% to 35% of all the seeds. We even had a issue with a night rodent maybe a rat who ate some of the seeds. So the seeds need to be in a space with light and far from the reach of any hungry insects or animals.

Transplanting Germinated Bamboo

So we decided it was time to transplanted the germinated bamboo seeds into pots today.

Update 9th April 2019

So after transplanting the tiny bamboo seedling into some smaller pots this is how it looks right now. It sees that the bamboo plants need some time to adapt to the new soil.

Soursop uses and recipes

Ok we all know about the amazing health benefits of the soursop fruit and leaf by now. In case that you missed the health benefits a quick summary: Soursop contains more than 200 chemical compounds in its pulp, leaves, and stems that contribute to its many health benefits. It’s particularly rich in alkaloids, phenols, and acetogenins. The average soursop fruit is full of vitamins and minerals like magnesium, vitamin C, potassium, thiamine (or vitamin B1), calories, protein, carbohydrates, fiber and more.

But what about uses and recipes. Lets dive into all the tasty and ideally healthy products we can make from organic soursop. As you know we at PermaTree focus on healthy stuff. So – no sugar, no milk, nothing that destroys the natural superfood that the soursop is. You must know that for example milk destroys the antioxidants.

Antioxidants are substances that prevent oxidation. Antioxidants are produced in your body and can be found in your diet. They help fight free radicals, which can damage cells and contribute to aging and disease. Some research has shown that mixing milk with antioxidant-rich foods and beverages may reduce or block their ability to fight free radicals.


And other classical additional ingredients like sugar. Well… we don’t need to elaborate on all the negative health effects of sugar. Best is to just focus on natural sweet foods like banana, sweet potato etc…

Possible uses of the Soursop fruit

General Soursop Consumption:
1. Eating the fruit raw.
2. Drink it.
3. Cook it.

Soursop Fruit-Pulp:
Pulp, Juice, Wine, Yogurt and Ice-cream. Also semidried Fruit or Fruit Powder.

Soursop Seeds:

Soursop Leafs:

Also soaps, domestic cooking oils, essential oils, herbal medicines, alcohol, fertility drugs, and insecticides

Soursop Recipes

Most important recommendation here is that you keep in mind that: Less is more. What ever recipe you have use it as inspiration. But keep in mind that less ingredients is normally healthier option. And all the health benefits of the soursop or the cacao are not destroyed by adding lots of not needed additional ingredients…

The Soursop Juice

The Soursop being a super healthy tropical fruit needs no additional ingredients except water. Peel the soursop fruit removing the green skin. Mix 50% ripe white soursop flesh without the seeds with 50% water. Blend the white soursop flesh for about 30 seconds.

Photo: 100% Fresh Soursop Juice
Photo: 100% Fresh Soursop Juice

Tool of choice would be a blender. Don’t strain the white soursop flesh (you would miss the health fiber). Also no need add any flavoring ingredients or use ice. If you want the juice to be cold keep it in the fridge for a while.

If you got a organic Soursop it should be naturally super tasty. The best tropical juice ever should taste like a combination of strawberry and pineapple, with a hint of creaminess and sour citrus.

Drinking a 100% organic Soursop will give you the following health benefits: High levels of vitamin C keep the urinary tract clean, and vast amounts of fiber improve digestive health. The fruit juice also contains a number of other nutrients, including potassium, magnesium, thiamin, copper, niacin, folate, iron, and riboflavin.

The Soursop Tea

Firstly you will need dried or dehydrated organic Soursop leafs. The Soursop fruit tree is normally managed while adding foliar (leaf) and soil fertilizer. Why is this relevant? Because if the fertilizer or the treatment is not organic you will be drinking that in your tea. So be sure to get it from a transparent farmer or a source you can trust. Good luck. Secondly you will need to heat up some water until its boiling. Then you will add something like a spoon (2 -3 leafs) of the dried Soursop leafs which are most likely not in their leaf form but in smaller pieces.

Practitioners of herbal medicine use soursop fruit tree leaves to treat stomach ailments, fever, parasitic infections, hypertension and rheumatism.

Bamboo Potential for Regenerative Micro Enterprises

As of March 2019 we have our 3rd anniversary at PermaTree. Living on-site and off the grid in this very unique tropical climate, we are now, better able to understand what works best. We try to focus on less work. Even if thats not visible yet 🙂 but hopefully in the not so far future, it will be. Anyway. For us it its now crystal clear that Bamboo is one of the most promising regenerative resources. Im a bit surprised that bamboo is not more talked about and used in permaculture theory. Because from a permaculture philosophy bamboo is predestined to be a key element in any permaculture design.

Stacking Functions

In efficient permaculture design we speak about getting many yields (outputs) from one element (thing) in your system. This is often called “Stacking Functions”. Every function is served by multiple elements and every element serves multiple functions. Elements are parts of a system. They can be plants or animals (wild or domestic), structures (tree-nursery, access road, house), or even established systems (chicken cop, fruit orchard, fishpond). Functions have to do with movements, they are everything an element does, wanted or unwanted.

For example wild snakes passing by our farm are on occasion an element. And among its functions is to take wake up our dogs and eat the young chicks and scare the chickens. But the same element (snake) also serves other functions. That are more directly use-full for us, for example keeping the rat population and venomous snakes in check.

Stacking Functions of Bamboo

Bamboo provides shade, filtered water, shelter for wildlife, carbon fixation, produces mulch and building materials, be a wind break, fertilize the soil (the leafs are nitrogen fixer when they break down), erosion control, natural water tank, slow down water flows across surface, provide a consistent supply of food, charcoal, construction material, etc. The Bamboo grass is ideal because of all the stacking functions. It can do a lot of different work for us in our system.

Next part is even more exiting. Because with Bamboo providing a consistent almost never ending supply of raw material we can start to create use-full things. From edible bamboo shoots, to music instruments, construction and medicine. Even beer, accessories and furniture. But also textile fabric, paper, cardboard, floorings and the best is innovative people are discovering new applications for bamboo everyday.

Bamboo Added Value Products

Image: Use-cases of Bamboo products

Now we could say the same thing about oil and one derivate which is plastic which has many use-cases. Whats the big difference? Bamboo is truly regenerative. Obviously oil and plastic are not at all regenerative. It will be a big challenge for future generations. To get rid of all the plastic trash produced in the last 100 years. Why is Bamboo regenerative? Well Bamboo can be harvested continuously in a sustainable manner. Did you know that: edible bamboo shoots appear from the roots every year. And grow to harvestable condition in just 4 or 5 years. Far faster than slow-growing hardwoods. Bamboo is the fastest growing plant on the planet. This is because Bamboo is part of the monocotyledonous flowering plants family known as grasses (Gramineae) and is not considered a tree. There are more than 1500 endless Use-cases of Bamboo (!!)

Yearly Bamboo Plant Cycle

Bamboo Micro Enterprises Opportunities

Bamboo Project Timeline

The Bamboo plant has a very strong potential of being transformed into a number of high-value products. This is one of the many reasons why bamboo deserves more attention. From decision-makers striving to bring new economic growth potential to their countries. Bamboo offers a range of business opportunities to private sector entrepreneurs and local economies. Income generating and micro-business uses range from crafts to furniture, from flooring to textiles, bicycles and even beehives. And, with increasing urbanisation in much of Africa, bamboo is a valuable resource for construction. As strong as steel, but renewable and with a far lower carbon footprint, bamboo can be an excellent and affordable building material. Particularly – but by no means exclusively – suited to areas prone to earthquakes. In China, emerging industrial applications for heavy industry are showing how bamboo has ideal strength properties to replace concrete and PVC for grills needed for cooling high temperature steam in many industries.

Is bamboo industrialization profitable?

Example from Colombia: At what scale is bamboo industrialization profitable?

There is a great analysis from Jörg Stamm regarding the profitability of the bamboo industrialization. This essay begins with the experiences of the author in the civil construction with bamboo and the craft manufacturing of laminated guadua angustifolia in Colombia, South America. With the data obtained in these experiences on input costs and small-scale returns, there are projections on a medium production scale. Such as bamboo industry machinery in China of the Woven Strand Board (WSB, also called “Strand Woven Board”). Also larger scales with automated wood industry lines in “commodities” such as the Oriented Strand Board (OSB) and Middle Density Fiberboard (MDF).

Surprising and very challenging, on the other hand, is the fiscal policy environment, which punishes industrial development with various types of direct and indirect taxes. The report also names niche markets with high added value and research, which propose the use of bamboo fibers with epoxy resin. For replacement of steel bars in concrete constructions by high density compounds. An analysis of different technologies with the natural Bamboo as natural resource. Read the full industrial bamboo potential (2016) from Jorg Stamm here.

Environmetal use of Bamboo

Bamboo for land restoration, a valuable environmental asset When it comes to restoring degraded land, bamboo is a powerful ally. Wherever it grows, bamboo protects and rehabilitates the surrounding environment. By conserving soil and water and improving the quality of the land. The plant grows rapidly slowing degradation and repairing damaged ecosystems. It is particularly suited to reforestation, afforestation, agroforestry and watershed protection.

Photo: Bamboo for land restoration

Its robustness and ability to thrive on the poorest of soils. Means that bamboo will thrive where other plants cannot survive. This makes it perfect for rehabilitating land damaged by erosion or industrial activity. Bamboo is used to help repair severely degraded land and ecosystems, while producing new revenues for local communities.

Bamboo also provides rapid reforestation. And in in doing this, contributes significantly to combating climate change, offering large-scale carbon sequestration. As a versatile material that can replace timber for the manufacture of a wide range of products. Bamboo will play an ever-increasing role of relieving pressure on timber forests.

Adaptive Contour Access Path (ACAP)

With the Adaptive Contour Access Path (ACAP) our focus is:

  1. Enabling improved manual access to the crops.
  2. Enhancing the soil quality with nitrogen fixing plants – Arachis Pintoi.
  3. Let the microorganisms do their magic with the soil – Vetiver Grass.
  4. Reducing erosion on a micro and macro level.
  5. Slowing down the water flow. Tropical rainfall can be extremely abundant quantity of water in short time.
  6. High efficiency in food crop production.
  7. Economically feasible solution.
  8. Creating diverse types of mulch material on site.

Experimental Zone Information

Aerial Photo: Experimental Zone (Steep Hill Farming) Information – ACAP

Our test site is located in a area with a elevation is 875-950 meter above mean sea level. Its about 1 Hectare in size. The slope is very steep. Its between 26° and 45° degrees steep! We have a average annual rainfall of 1000-1500 mm per year. The soil consists mainly of – Ultisol – red clay with high mineral content. Within the Köppen-Geiger classification we are in the Tropical rainforest climate.  Monthly average rainfall of 170mm, yearly almost 2000mm.

Adaptive Contour Access Path (ACAP) 

So basically we are using the different inspirations such as: “Contour Hedgerow Alley Intercropping” and the “SALT-System”. With the primary need to enable access within our crops on a literary VERY steep slope. Thats how we came up with the idea of the Adaptive Contour Access Path (ACAP).  Building graduated terraces on the hill with the help of heavy machinery is not always a option, because of the economic cost and the accessibility to the parcel.

So the alternative is to create only the most needed part. In our case that consists in a access path, of 20-40 centimeters width, following vertically the contour elevation within the slope. Now in our case we built it adaptively to the actual contour line. Because its not 100% on contour line. It depends on the procentual steepness of the slope. The steeper the slope, the closer the contour access path should be; conversely, the flatter the slope, the wider the spacing of alleys. To rebalance the difference spacing, we build all the access path adapting slightly up or down the contour lines, depending on the slope steeples.

Adaptive Contour Access Path (ACAP), PermaTree BirdView
BirdView-Illustration: Adaptive Contour Access Path (ACAP), PermaTree

So every 5-8 meters we build another Adaptive Contour Access Path (ACAP). In between them we have alleys which we use to plant intercropping 5x5m (triangle) permanent producing fruit trees, shrubs and herbs as well as endemic flowers. In a second phase we will plant alternately perennial crops between the permanent annual crops. Because with the spacing of 5×5 meters until the permanent producing fruit trees grow there is plenty of space. Even once those fruit trees are producing there will still be enough space for different crops, on different food forest levels, thinking in 3D farming. Plant short- and medium-term crops between and among permanent crops.  Now every now and then there is a fruit tree near to the access path.

In between that space we plant Vetiver grass. Like a contour hedgerow. Once the vetiver grass has grown mature, it can be trimmed down to 25 centimes every 3 month. The left over material is ideal mulching for below the fruit trees. Instead of having to buy organic material the cut off vetiver grass will break down within 30-60 days in a tropical climate with lots of sun and rain.

As ground cover we use Arachis Pintoi. Both elements will help within the system to evolve. The Vetiver roots are very dense and deep and will attract microorganisms and thus enhance the soil quality. The Arachis Pintoi is the perfect tropical climate ground cover processing nitrogen from the air and into the soil in a collaborative relationship with soil organisms. This system is holistic because including the endemic flowers such as Heliconias we provide food (nectar) for the birds and insects such as the different type of stingless bees we have on the farm. They will help with pollination of the fruit flowers and will produce. Obviously existing fruit trees such as Theorboma Cacao and Bitter mandarin will be part of the system. 

At the highest level of the ACAP we will plant giant bamboo (Dencrocalamus Asper) to have a constant production of nitrogen fixing leafs landing on the system slowly running down and breaking down. Also the giant bamboo will help filter water and slow down the water flow. Every bamboo stem will be filtering water and will act as a natural water reservoir in case of a dry period.

ACAP Agroforestry Enhancing Biodiversity

So obviously our goal is to enhance the biodiversity. To increasing our food production security not just in a sustainable way – but in a self-sustainable totally renewable way. By enabling all the players to have a mayor positive impact within the test zone. We have planted about 18 different plants – most of them for food production. Planting spacing in triangles 6x6x6 meters to allow maximizing photosynthesis with an average of 12 hours of sun light. Unlike classic agroforestry / syntropic farming practices we have not planted the fruit trees in rows, but have something more like extreme polyculture with a almost random assembly method.

We picked the fruit species randomly with the exception of never planting twice the same species one bordering the other. This should enhance diversity from within. Time will tell. But not only. Also focusing on enhancing the microorganism and mycorrhiza of the soil on different levels with Vetiver and Arachis Pintoi. Or the endemic insects and tropical stingless bees with a diverse tropical flowers: Heliconias, Hibiscus and two local shrubs that have lots of round yellow flowers.

Vetiver Grass (Chrysopogon zizanioides)

Vetiver tolerance to the extreme climate fluctuations such as prolonged drought, flood, inundation. Waterlogging tolerance extended to 45 days and the withstand temperature range from-100C to 480C. When planting vetiver will grow each dust (like lemon plants), there is no need to take it (bull spread as reeds). Therefore, when it will grow as time grows planted in rows, not grow rampant as weeds. It features not produce seeds, propagated mainly by asexual methods should not fear the spread uncontrollably. Besides, sharp vetiver leaves and roots of aromatic odor, capable of banishing snakes, rats and other rodents. 

Additionally thanks to the development of deep and dense root system, vetiver has the ability to absorb toxic in water and soil factors such as heavy metals, chemical plant protection.

Perennial Peanut (Arachis Pintoi)

As a nitrogen fixer the rhizomes of the perennial peanut process nitrogen from the air and into the soil in a collaborative relationship with soil organisms. Thus providing a free alternative to the nitrogen salts of chemical fertilizers. With its extensive root system, rhizoma perennial peanut spreads across the ground as a sod grass would perform.

Arachis Pintoi can be seen as living mulch (ground cover growing around the fruit trees). This is an management strategy that improves soil quality, reduces ground clearing weed maintenance by growing into a dense ground cover.  

SALT (Sloping Agricultural Land Technology)

SALT is system on soil conservation and food production, integrating different soil conservation measures in just one setting. Basically, SALT is a method of growing field and permanent crops in 3-meter to 5-meter-wide bands between contoured rows of nitrogen fixing trees. The nitrogen fixing trees are thickly planted in double rows to make hedgerows. When a hedge is 1.5 to 2 meters tall, it is cut down to about 75 centimeters and the cuttings (tops) are placed in alley-ways to serve as organic fertilizers.

SALT is a diversified farming system which can be considered agroforestry since rows of permanent shrubs like coffee, cacao, citrus and other fruit trees are dispersed throughout the farm plot.  The strips not occupied by permanent crops, however, are planted alternately to cereals (corn, upland rice, sorghum, etc.) or other crops (sweet potato, melon, pineapple, castor bean, etc.) and legumes (soybean, peanut, etc.). This cyclical cropping provides the farmer some harvest throughout the year.

Soil Erosion

The greatest problem man will encounter when forest trees are cut extensively without replanting and improper farming of fragile, sloping lands is soil erosion. The erosion of the topsoil. That thin upper crust on the earth’s surface on which man plants his food crops. Is an extremely serious issue in the amazon basin of South America.

First Giant Soursop (Annona muricata) fruits

As of the 25th of December 2018 we have had the first 60 Soursop fruits which are growing and starting to ripe now. When we first planted 100 different fruit trees, back in 2016, the soursop stood out because of its rocket like growth. Compared to the citrus fruit trees all of the Annona (Soursop, Rollina) and Artocarpus (Jackfruit, Breadfruit) fruit trees have grown extremely faster within our tropical climate. Later on we learned from a CEDAMAZ study that the Annona Muricata fruit is endemic to our Valley of the Fireflies (Valle de las Luciérnagas) here in the Zamora-Chinchipe region of Ecuador.

Did you know that the English name, “soursop” is derived from the Dutch “zuurzak”? Which means “sour sack”. In the German language the Soursop is known as “Stachel-Annone”. “Guanábana” is the local name in Ecuador.

The Soursop is a extremely tasty tropical fruit. With an average Brix value of unconcentrated natural fruit juice of 17.2° (degrees) it is sweet. It has flavors that are a combination of: Strawberry and pineapple, with sour citrus flavor notes that contrast with its creamy texture, which is similar to the flavors of coconut and banana.

Image: One of the very first Soursop (Annona muricata) fruit juice from the PermaTree Farm in Ecuador

Although the Soursop rind is quite bitter, the fruit’s flesh is soft, smooth and sweet. It provides healthy carbohydrates as its major nutrient. The soursop also contains a significant amount of vitamin C and several B1, B2, B3, B5, B6 vitamins such as thiamin, riboflavin and niacin. Along with a high amount of alkaline forming calcium, an important mineral for bone health.

The white pulp segments of the soursop fruit (75.6%) are primarily seedless, although it has an average of 171 seeds (5%) per fruit. Bark and seeds are toxic and contain poisonous alkaloids such as anonaine, muricine, and hydrocyanic acid. The seeds are also used for medicinal purpose of killing certain parasites.

The edible white pulp can be eaten raw. But it is also used to make fruit nectar, smoothies, fruit juice drinks, as well as candies, sorbets, and ice cream flavorings.

Research program on Amazonian Fruit from CEDAMAZ

Image: From CEDAMAZ – The Spanish name of the Annona muricata is Guanábana. In our region of Zamora-Chinchipe it grows within the 800 to 1000 m.o.s.l. It can’t grow lower than 800 m.o.s.l because its the lowest part of the valley base where the river Zamora flows. You can read

Not so long ago found some interesting data from the Nacional University of Loja in Ecuador (Universidad Nacional de Loja). It stated that a few years ago the CEDAMAZ started a research program about Amazonian Fruit (FRUTAMAZ). To identify, characterize and propagate the most promising native fruit species. With a focus on high nutritional importance as an agricultural crop alternative for the region.

Within this research program, at the end of 2010, the CEDAMAZ had identified, 31 promising fruit species originating from different corners of the province of Zamora-Chinchipe. The main species are: Moriche/Buriti palm (Mauritia flexuosa), Sacha Cherimoya (Rollinia Mucosa), Breadfruit (Artocarpus Altilis), Borojo (Borojoa Patinoi), Cacao Theobroma, Wild Cacao (Herrenia sp.), Camimito (Pouteria caimito), Peach Palm (Bactris Gasipaes), Cupuaçu (Theobroma grandiflorum), Guaba (Inga sp.) and last Soursop (Annona Muricata).

Health Benefits of the Soursop (Annona Muricata)

Practitioners of herbal medicine in Asian, African and South American countries have used the bark, leaves, root, and fruits of the soursop tree. To treat infections with viruses or parasites, arthritis, depression, stomach ailments, fever, parasitic infections, hypertension and rheumatism. The Annona Muricata fruit is also used as a sedative. Read more about all the additional Healing Benefits of the Soursop.

Steep Hill Tropical Agroforestry Soursop Zones

soursop plantation overview map - permatre, Ecuador
Image: Our Soursop plantation overview map. As you can see we have been organizing all the plantation in different zones. Between the soursop zones we have different food forest zones and lots Bamboo. As Ground cover we use Arachis pintoi – which is a great forage plant. Should help us in connection with the 15’000 Vetiver grasses matts we have planted within the access path to slowly improve the soil quality.

Giant Soursop Fruits come in all shapes and sizes

Clearing zone-G for additional Fruit Tree PolyCultures

When we talk about cutting pasture grass. It’s not the same thing in a non tropical climate like in Europe. The grass here is GIANT Elephant grass (the African Pennisetum purpureum, also known as giant king) which grows up tu 3 meters tall and is very thick up to 1cm! Check out the photos.


So it’s a real challenge to cut it. Even more to get rid of it. The only natural solution we found so far after doing various experiments over the period of 24month is, 1st cut it and 3 weeks later when it has grown back to 20cm high, we fumigate it with a natural solution which contains urea (Chemical formula‎: ‎CH4N2O) / nitrogen (N). Then the nitrogen will be sucked up by all the Gramineae (family of monocotyledonous flowering plants known as grasses,) and within 14 days the Gramineae-plant starts to dry out. We have a success rate of about 90%. So after a while we have to go back once or twice to get rid of all the grasses. Which obviously ? are not endemic to this region and where brought with the idea of removing all the Amazon jungle forest to make space for more cattle farming … Since the beginning of the colonization in the 1960s, around 15% of the Amazon forest has been removed through agricultural practices.

The giant grass will be replaced with the following polyculture according to our previous learnings with the adaptive keyline access path with Arachis Pintoi & Vetiver grass.

Adaptive Contour and Erosion Control with Vetiver grass and Arachis Pintoi

Tropical Permaculture

Here we have a A-typical climate at PermaTree at the edge of the amazonas region in Ecuador. Most of the year too much rain. Too much water. Lots of issue with erosion and high difficulty of access with very steep hills.

Access path with Vetiver and Arachis Pintoi

So to improve this we have implemented something like access path in conjunction with vetiver grass on the falling hill side and additionally been planting Arachis Pintoi to first or foremost cover the soil.

Birdview: Adaptive Contour Access Path

With our very humid climate, swales make no sense. So here its not about the classic water harvesting.
Our focus at PermaTree in the amazonas region is clearly about:

  • Slowing down the water flow (lots and lots of tropical rainfall)
  • Reducing erosion on a micro and macro level
  • Enabling better manual access to the crops (Soursop fruit can get up to 15kg in weight!)
  • Improving the soil quality with nitrogen fixing plants like Arachis Pintoi and Vetiver grass

Adaptive Contour

To be honest ideally we should of have build first the access path on contour lines  and then plant the crops also on contour hight. But hey … we are learning on the hard way here 🙂

This is why we call this “Adaptive Contour”.

Using contour plantings such as vetiver grass to hold soil on steep hillsides with crops integrated between rows of contours.

Adaptive Contour Access Path

PermaTree: Adaptive Contour Access Path

As you can see on the image we have two keyline points / water holes which flow into a pond to store the water. Along this creek we have planted lots of bamboo to again slow down the water flow and increase soil quality with the bamboo root system and bamboo leafs which are a great source of nitrogen.

Also you can see the very green spot – there we initially planted the Arachis  Pintoi – its so green because it has already spread very well there. on the left side you side that it is still growing and needs some more time to get to the same level of green. On the left side you can see there is no Arachis Pintoi yet, so we will need to transplant it there too within the next rainy season.

If you look closely you can see where the excess water from the saddle dam is traveling down into the valley towards the pond where the grass is greener and vetiver grasses have been planted. Currently its summer so we cant do any transplanting.

Contour Hedgerows

Example of a hill with slope also using Contour Hedgerows. Using contour plantings such as vetiver grass to hold soil on steep hillsides with crops integrated between rows of contours.


Vetiver grass = Vetiver is native to India and is one of the best management practices to control erosion. This non-fertile, non-invasive perennial grass as a dense web of roots that binds soil and penetrates vertically to 15 meters.

Arachis Pintoi

Arachis pintoi is a forage plant native to Cerrado vegetation in Brazil. It is native to the valleys of the upper São Francisco and the Jequitinhonha rivers of Brazil.

Keyline = Keyline design is a landscaping technique of maximizing the beneficial use of the water … of Yeomans’ Keyline design system is the Keyline Scale of Permanence ( KSOP), which was the outcome of 15 years of adaptive experimentation.

Swale = A swale is a low tract of land, especially one that is moist or marshy. … Artificial swales are often infiltration basins, designed to manage water runoff, filter pollutants, and increase rainwater infiltration.

Contour line = In cartography, a contour line (often just called a “contour”) joins points of equal elevation (height) above a given level, such as mean sea level. A contour map is a map illustrated with contour lines, for example a topographic map, which thus shows valleys and hills, and the steepness or gentleness of slopes.

Cacao Fino de Aroma


We produce Cacao Fino de Aroma

At PermaTree we produce Cacao Fino de Aroma. Fruity and flowery aromas and flavour with nutty malt notes. This is the characteristic flavour of Cacao Fino de Aroma that distinguishes it from other cocoas in the world. The Fino de Aroma denomination is an International Cocoa Organization (ICCO)* classification, which describes an exquisite aroma and flavour.

Only around 8% of the cocoa produced in the entire world is Cacao Fino de Aroma.

76% of Cacao Fino de Aroma produced in the world is grown in Colombia, Ecuador, Venezuela and Peru.

Origin & History

Drinking chocolate dates from pre-Colombian times to the Native American civilizations that populated Central and South America. It was particularly favorited by the Mayans who considered it a sacred gift from the gods.

Traditional knowledge and practices related to cocoa cultivation, consumption, transport and marketing are part of a process of historical and cultural construction that have remained unchanged over centuries. Recent studies in Palanda, county in the province of Zamora Chinchipe, show that at least one variety of Theobroma Cacao has its origin in the Upper Amazon, according to archaeological evidence found in the culture called Mayo -Chinchipe where confirmed use of cocoa from 3,300 BC in Santa Ana -LaFlorida site located 1,040 meters above sea level.


Ethical & Authentic

There are plenty of delicious chocolates around the world, but when choosing the ingredients, one should not only look at the price, but also at the quality, and whether the raw material comes from an authentic and sustainable source.

If you consume Starbucks or Nestle (global big brand) chocolate, most likely its not ethical because:

1. Labor Practices
Child labor, and in some cases, child slavery, are common practices on West African cocoa farms, where 75% of the world’s cocoa is produced. Children on cacao farms may endure long workdays, using heavy and potentially dangerous tools to harvest cacao pods.

2. Ingredients

Safe bet is to choose chocolate bars and chocolate-containing products that do not contain palm oil. Try to buy chocolate with no sugar much more healthy. Also try to eat chocolate with no diary /milk because studies have found that by adding milk this actually blocks the absorption of antioxidants in chocolate(!) While processed chocolate may taste delicious, the benefits of cacao are only found in the raw form.

3. Production Practices

Nearly all cacao is grown in West Africa or Latin America, and additives like vanilla and cane sugar are also grown in far-away places like Madagascar, Indonesia, South America, and Thailand. Keep in mind that consuming chocolate certainly doesn’t make your carbon footprint any smaller. It is also important to recognize that chocolate is a luxury and enjoy it as such. Make the best, most informed decisions you can, and savor each bite of it.

Currently in Ecuador its a real challenge as small organic cacao farm to live from selling cacao. We hope we can help and change this for the future. Let us know if you believe you can help us in this endeavor.

BTW previously we wrote a blog article step by step guide of cocoa to chocolate


Where is PermaTree in Ecuador?

PermaTree is located at the edge of the Andes mountain range and the amazon basin. The Amazon river system has its sources in the eastern flanks of the Andes. The Andes are the longest exposed mountain range of the world, and the second-highest after the Himalayas. The Andes mountain range is the highest mountain range outside Asia.

From this picture you can see on the top left the pacific ocean where the city of Machala is. On the right top side you can see Ecuador biggest city with about 2 million habitants which is Guayaquil. The brownish part in the center is the Sierra. Here on the right side is the colonial city of Cuenca which also has a airport. From the farm to Machala it can be a good 9 hours car ride. If you take the bus it can be longer.

On this picture you get an idea of the elevation and mountains which are around us. Also you can see part of the farm property location. Its not a flat farm 🙂 Lowest part if 800 m.o.s.l. and highest part is 1300 m.o.s.l

Keep in mind the river you see is the Rio Zamora which has more a less an elevation of 800 meters over the sea level. All surrounding it is higher. On the top of this picture you can see some peaks which most likely are some of the many active volcanos of Ecuador. The top of Mount Chimborazo in the Ecuadorean Andes is the point on the Earth’s surface most distant from its center. Mount Chimborazo is an inactive volcano in Ecuador, which last erupted over a thousand years ago.

Above is a updated touristic map of the canton de Yantzaza. PermaTree is located in the center where it says “Los Encuentros”. To be fair we haven’t seen 1% of all the things which are displayed here because we are busy building the farm and if we do have a few hours to chill we rather go and have a swim in our own natural pool 🙂
