Aplicação de técnicas de geoprocessamento no desenvolvimento de mapas de fertilidade do solo

Abstract

This study shows geoprocessing techniques through a plugin called Smart-Map by the software QGIS, making a comparison among the interpolation methods, aiming at producers who want to acquire precision agriculture techniques to obtain better income in their properties. The goal of this work is to realize the elaboration of the maps of chemical atributes aspiring a cross analysis among the obtained data, then it is possible taking factual and specific decisions, with focused analysis in two statistical methods, “Ordinary Kriging” and “Machine Learning”, decreasing the production cost and increasing the profits of the producers. The research was realized in the city of Marmeleiro – PR. The área has 9,8 acres, in the coordinates -26.2524097 of South latitude, - 53.1089066 in the West longitude, with medium altitude of 650 meters. It may have a progress in the productive of grains which may be incorporated to the fertility map that was elaborated. With the assistance of the precision agriculture it may decrease some costs of production, reducing the environment impacts caused by the excesses and it also increases the profitability of the producer.
