PLANTAS DE COBERTURA EM SISTEMAS DE PRODUÇÃO DE SUCESSÃO ENTRE AS CULTURAS DE SOJA E MILHO

Abstract

In Brazilian regions such as the Midwest, the production system adopted by grain producers is the succession between soybean and corn crops. Cover plants are intended to cover, protect the soil and provide straw for the No-Till System (SPD), in areas that would be intended for fallow or preceding commercial crops. Therefore, the objective of this work was to identify the main cover crops and the benefits they provide, whether isolated or in a mix, to increase commercial crops in succession in the no-tillage system. theoretical study, through an exploratory literature review research. In the absence of soil preparation, with plowing and harrowing, the plant roots are responsible for conditioning the soil for the next sowing. As for the choice of cover plant, the producer must choose species that meet their needs and that have a good adaptation to the region. The use of cover mix has become important in Cerrado soils, which are mostly acidic, with low organic matter content and low fertility. Some studies need to be done regarding the use of cover crops, especially with mixed species. , to select the species that best match each other and which are better adapted to a given region, ensuring greater efficiency of these plants, improving soil quality and productivity of commercial crops that will be cultivated in succession.
