Mapeamento das áreas potenciais para o plantio de soja no município de Santa Filomena-PI

Abstract

The production of soybeans is among the economic activities that, in the last decades, presented more expressive growths. In the world context, Brazil has a significant participation in the supply and demand of products from the soybean agroindustrial complex.This has been possible through the establishment and continuous progress of a well-structured production chain that plays a fundamental role for the socio-economic development of several regions of the country. The soybean crop in the state of Piauí assumed an important scenario, soybean production increased by 3,500 times, with the principle of 0.2 thousand hectares, in the 1987-1988 crop, for an estimated 714 thousand hectares in the 2015-2016 harvest (CONAB, 2018). Currently the applications of remote sensing and geoprocessing in environmental analyzes have been very efficient, tconsidering the ease of representation of the cartographic spatiality of the analyzed phenomenon and the integration of the data by themati mapping. The objective of this work was to map the potential areas for soybean planting in the municipality of Santa Filomena, using geoprocessing techniques. For this, supervised classification was performed using images of Landsat 8 satellites of the year 2018.The land use mapping of the municipality showed the locations where soybean cultivation is cultivated among other classes. After the generation of all the other maps an area subtraction operation was done, that is, map algebra, where the areas that are still available for agricultural cultivation were identified. The results were satisfactory, reaching the proposed objectives
