Integration of legumes and vermicompost in maize cropping systems en Costa Chica, México.

Abstract

Farming systems in Costa Chica, Mexico face problems related to soil degradation and low
crop productivity. To improve cropping systems several experimental trials that included fertilization
and intercropping of canavalia were carried out in farmers´ fields. The integration of canavalia
and organo-mineral fertilization had positive effects on weed suppression, grain yield
and nutrient uptake. These are options that in the long term can enhance soil organic matter.
