The pruning of the vetiver grass at its right time works like a carbon bomb
Like with many other elements within the PermaTree farm we are using vetiver grass, within systems such as the Adaptive Contour and Erosion Control with Vetiver grass and Arachis Pintoi. As usual the more one element can be interconnected with other elements and create more functions. The more value every single element will bring on a macro scale. Our goal is always to be able to stack elements of high value to get a final function of even higher value. Obviously the goal is that all those systems work self sustainably and are ideally regenerative.

Pruning of vetiver fences up to a height of 30 to 50 cm. prevents these from giving seeds, makes them thicker and consequently more effective in filtering runoff water and erosion.
At the ende of the day vetiver gras is being used at PermaTree in Ecuador for the following use-cases:
- Crop fertilization with pruned vetiver grass (contains minerals)
- Erosion control – bioengineering
- Phytoremediation of water and soil contaminated by heavy metals, hydrocarbons, agrochemicals, and other pollutants.
- Keep in mind vetiver has more than 1000 uses (construction materials, forage for livestock, landscaping and ornamentals, mulch, compost, veneer, fiber board, ash for concrete work, and insecticide)
Transplanting Vetiver Grass
Vetiver as Photosynthetic Energy Accumulator
Seeing vetiver grass as a “photosynthetic energy accumulator”, both on the ground in the form of plant biomass and under the ground as a creator of fertility due to the fixation of organic carbon, through the decomposition of its roots and the creation of Microbiological networks, we wonder how we can obtain the greatest amount of energy through its pruning or cutting.

The Logic behind the Pruning the Vetiver Grass
When vetiver grass grows, it reaches a maximum growth point (2 meters), where it stops growing and prepares for flowering and planting. There is the ideal time for its cut, since its roots have also been expressed as much as possible under the ground. In terms of energy saving, the grass, being pruned aerially, immediately cuts its roots, releasing all fertility to the soil. Then, we let the grass grow to its maximum potential, so that it accumulates or “captures” the maximum carbon (load) and then we cut it (it is unloaded). This works like a two-phase carbon pump, with a charge pulse and a discharge pulse.
