Mapa de rentabilidade da soja no sistema de integração lavoura-pecuária em solo arenoso

Abstract

One of the objectives of current agricultural production systems is to continue to develop technologies that increase productive efficiency through sustainable management practices. Thanks to the development and inclusion of these new technologies and their tools, we have modern, competitive and sustainable agriculture. In agronomy, we have the ILP integrated system as a tool, from precision agriculture we have soil mapping, economic engineering, analytical techniques and simulations of different economic scenarios. All these sciences made it possible to understand the quality of the soil, the prediction of productive potential, not only as a general average, but also at each sampling point. This research was carried out at Fazenda Nelore CV in Caiuá-SP, in an area of 195 ha, in an integrated ILP system. The objective of this work was to analyze soybean profitability in an integrated crop-livestock system in sandy soil using georeferenced productivity data. The research area was divided into three 50 ha plots and one 45 ha plot. The soil is classified as a red Latosol with a sandy texture that presented a variation from 30 to 150 Kg-1 in clay contents. Data collection was georeferenced to allow correlation between parameters of fertility, soil physics, productivity and profitability. The generated data were grouped into tracks, whose data will be used for the elaboration of maps of spatial distribution. There was great variation in the yield obtained by the georeferenced harvest monitor, the lowest yield was 1,185 kg ha-1 and the highest yield was 4,382 kg ha-1, resulting in a difference of 3,197 kg ha-1. This difference in productivity considering the value of the bag on 06/20/2021 resulted in the value of R$ 6,000 per hectare.
