Sistemas de correção diferencial no piloto automático e qualidade da semeadura pneumática e mecânica

Abstract

Precision agriculture is a technique that is being used today, applied for the management of spatial and temporal variability of field management. There are some tools among them the autopilot that works with differential signals of correction for your direction. There are also several models of seed drills. Thus, the objective of this work was to evaluate the differential signs of correction and the performance of two seeder-fertilizers, one being equipped with the mechanical doser and the other with a pneumatic doser. An area where the same characteristics for the correction signal test and the seed drills were selected, then equipped tractors were selected, with the RTK signal systems and the geostationary satellite. He proceeded with the evaluation of the passes between rows of the planter, thus measuring the spacings between them and observing the signal that obtained the least errors. In relation to the performance test of the seeder was counted the number of plants per meter. Based on the results, it was possible to conclude that the RTK differential correction system achieved better performance compared to the other signal, as the pneumatic seed drill did better in the destruction of seeds per meter in relation to mechanics.
