Straw production in different integrated crop livestock systems under no-tillage soil management.

An important annual crops management system for carbon sequestration from the atmosphere is the crop livestock integrated system managed under no-tillage system. In the Brazilian state of Mato Grosso, the problems pointed out in the integrated NT system are lack of crop options for rotation and insufficient soil cover. The research activities of the present study were and extension activity as demonstrative unit of crop options of combinations of plant species producing high amount of vegetable dry matter. In which were focused on the contribution of varied amounts of dry mass and straw production and surface accumulation to the soil from production models consisting of annual cultures, successions, rotations and/or crop consortiums. The results confirm crop sequence soybean and cotton, provide low dry mass production. The crop sequences and second crop season that contain high-biomass sorghum and the maize consortium with palisade grass are the ones that provide higher dry matter production in the form of straw, being often above that minimum values in the tropical humid conditions, to keep the soil organic matter content stable. The sequence of crop that includes hybrid biomass sorghum was the one that showed higher mass production and has the potential for recovery of soil cover for those soils.
