Sustainable Production Systems under No-till in the Cerrado of Brazil - Piaui

IPNI-2011-BRA-58

New alternatives of really sustainable production systems are necessary for the cerrado of Brazil. One crop system has been leading to diseases, soil degradation and low yields. Read more

Interpretive Summary

This project was conducted for three years, and 2014 represented the last year of the study. Continuation will not be possible due to many changes in the research team. In 2014, a severe drought occurred in several regions of the state, including the site of the project. After three years, a soybean crop followed by millet provided the greatest addition of biomass to the soil. No increase in soybean yield has been observed in this rotation despite an apparent increase in soil K recycling.

Continuous cultivation of lands under continuous monocropping systems tends to promote soil degradation and to increase the incidence of crop diseases, pests, and weeds that may reduce crop yield potential. This is a 3-year research project looking into various aspects of sustainable agricultural systems. The project gives emphasis to crop rotation and other alternatives to generating long-term profitability.

Continuous cultivation of lands under the same monocropping systems tends to promote soil degradation and increases the incidence of crop diseases, pests, and weeds, which in turn, reduces crop yield potential. This is a long-term research project looking into various aspects of sustainable agricultural systems. The project gives emphasis to crop rotation and other alternatives to generating long-term profitability.
