Abstract

With the need to increase food production and a consequent increase in agricultural productivity, the use of central pivot irrigation becomes an interesting alternative to guarantee this demand. The main objective of this work was to generate data on slope to identify areas suitable for installing a central pivot in the municipality of Santarém-PA. GIS software was used to classify the areas, using a Digital Elevation Model (DEM), and digital images from Google® to identify arable areas. The municipality has potential to increase its irrigated areas with predominantly Dystrophic Yellow Oxisol soil. Excluding restricted areas such as conservation units, approximately 96% of areas were obtained suitable for installing a central pivot irrigation system, with slopes of up to 15%, and 4% with slopes greater than 15%. The municipality presents data that demonstrate a favorable relevance for the use of this technology.
