Achieving sustainability in the use of green manures

Today, well over 125,000 farmers are using green manure and cover crops in Santa Catarina, Brazil. Green manure and cover crops are equally popular in neighbouring Parana and Rio Grande do Sul. In Central America and Mexico, an estimated 200,000 farmers are using 20 traditional systems involving some 14 different species of green manure and cover crops and organisations from central Mexico to Nicaragua are promoting their use in at least 25 additional systems.
