Biofertilizers Fermentation Plant-based

Fermentation

Biological transformation of the plant material by microorganisms (yeasts, bacteria) in total or partial absence of oxygen, releasing and transforming active compounds over a longer period than the other techniques (days to weeks).

Process summary

1) Chop the plant material and submerge it in water, in a wide, non-airtight container (to let gases escape). 2) Stir daily during fermentation. 3) Let ferment from several days to several weeks, depending on ambient temperature, until it stops foaming. 4) Strain and dilute before use — the undiluted product can be very concentrated.

Dark liquid draining from decomposing plantain stalks, rich in potassium according to the source, supplying partly decomposed organic matter and microorganisms.

Application

Application description: Diluted, as a liquid fertiliser for the farm's crops.

Dose: 200 ml per litre of water (20%).

Tips

Do not use stalks from plants showing symptoms of Moko or other diseases, so as not to spread them across the farm.

Preparation process

1. Select stalks from freshly harvested bunches, discarding any showing symptoms of Moko (bacterial wilt).
2. Chop them and place them under cover on a grid, with a container or pipe to collect the liquid.
3. Do not add water: as they decompose, the stalks release a dark liquid.
4. Pour the collected leachate back over the heap 2 or 3 times a week to speed up decomposition.
5. Leave for at least 30 days and store in lidded plastic containers.

  • Plantain bunch stalk (rachis) ⓘ

Tools and equipment

  • Strainer or filter cloth
