Suitability for Agricultural and Forestry Mechanization of the Uruçuí-Preto River Hydrographic Basin, Piauí, Brazil

Abstract

ABSTRACT:This work aimed to characterize the suitability for agricultural and forestry mechanization in the Uruçuí-Preto River Hydrographic Basin, state of Piauí, Brazil, in order to support the planning of use, interventions, soil management and environmental management for the study area. A terrain slope map was generated with use of ArcGIS 10.0 software by using the SRTM/DEM (Digital Elevation Model) basis, and processed and analyzed from the interpretation and attribution of slope classes in degrees in order to indicate areas with restricted suitability for mechanization. A map of soil types was generated in order to assist in interpreting the capacity to mechanization according to soil parameters, and from that we obtained the final map of suitability for mechanization in the basin studied. Based on the results, classes of suitability to mechanization of presented the following distribution: Palavras-chave: cerrado, avaliação de terras, planejamento agrícola, manejo de bacias hidrográficas, Sistemas de Informação Geográfica (SIG).Recebido em janeiro/2016; Aceito em maio/2016.
