Shifting abundances of communities associated with nitrogen cycling in soils promoted by sugarcane harvest systems

Abstract

Significance and Impact of the Study: Inspired by the environmental concern associated with the use of fossil fuels, several countries are encouraging the development of biofuels. Sugarcane cultivation supports Brazil as one of the largest world sugar and ethanol producer. In the last decades, we observed a change on soil-plant system in the productive system (manual to mechanized), but the impact of this change is underestimated. Soil quality was evaluated using microorganisms associated with the nitrogen cycle, and it was possible to observe that these biological tools were more sensitive proxies to indicate soil responses to different management strategies.

Efeitos da conversão pastagem-canavial e da intensificação do sistema de pastagem na microbiota do solo associada ao ciclo do nitrogênio

“…Considerando que os microrganismos do solo são os principais agentes das transformações do N na interface solo-planta-atmosfera, compreender a ecologia dos microrganismos responsáveis pelos principais processos relacionados à perda do N no sistema é de grande importância para o avanço do uso eficiente do N na agricultura (CASSMAN et al, 2019;RIGOTTO et al, 2020).…”
