Alternative Methodology
Description Compost tea is a liquid extract or a dissolved solution but not simply a suspension of compost. It is made by steeping compost in water for 3–7 days. It was discovered in Germany and became a practice to suppress foliar fungal diseases by nature of the bacterial competition, suppression, antibiosis on the leaf surface (phyllosphere). It has also been used as a fertilizer although lab tests show it is very weak in nutrients with less than 100ppm of available nitrogen and potassium. Other salts present in the tea solution are sodium, chlorides and sulfates. The extract is applied as a spray to non-edible plant parts such as seedlings, or as a soil-drench (root dip), or as a surface spray to reduce incidence of harmful phytopathogenic fungi in the phyllosphere.

Economics
Technology Development Level Pilot projects and first implementations;
Required Maintenance Technical Level Low: Technology to be maintained through its life cycle requires less common tools and/or training is required for maintenance;
Required Infrastructure for Deployment Low: Technology can be developed with less common tools, low development level supporting technologies and moderately trained personnel; Education and training required;
Required Resources during manufacture Metal, plastics, electronics, air pump;
Required Resources during operation Electricity;
Deployment
Level
Local availability;
Deployment Capability and Potential The technology can be deployed worldwide;
Requirements for Deployment The technology can be widely deployed but resources or material supply and distribution chains are required; Education and training required;
Relevance for Autonomy and Food Security High;
Environment Impacts (emissions) Low: no direct emissions (when operated with renewable energies) but indirect emissions; Composting emits CO2, CH4 and N2O, so a composting method with low emissions should be selected;
Conformity with Bio- Cybernetic System Rules Yes;
Additional information / Comments No comments.
