Korean natural farming uses Plant-growth promoting rhizobacteria
Soil
In KNF existing soil is amended by a mixture of cultured microorganisms, biochar and growth media. Microorganisms accelerate the conversion of organic compounds and other nutrients from dead plants and animals into a readily-absorbable form. Outputs can include antibiotics, enzymes and lactic acids that can suppress diseases and promote healthy soil conditions.
The basic approach proceeds in four steps, each of which produces a usable amendment. The process takes 3 to 4 weeks.
