Abstract

A sustainable environmental management, through a joint vision of natural resources, has been adopted for monitoring land sustainability, particularly those with agricultural use. This work aimed the characterization and definition of pedoenvironmental units, to provide subsidies to the development of sustainable land use plans, through the characterization of the main soil classes found in the Santa Tereza region, Tocantins State, Brazil, and their relations with the relief, geology, agriculture suitability, and land use and occupation, with the use of geoprocessing techniques. In the area of study, a pedological transect, with characterization of seven soil representative profiles, was conducted. The soils were classified as Dystrophic Rhodustox, Distrophic Plintustox, Distrophic Haplustox, Distrophic Haplustept, Typic Troppsamment, and Distrophic Tropsaprent, and over 63.5% of the total area was covered with native vegetation. According to the agricultural suitability evaluation, lands were classified as 2(b)c, 4p, 4(p), 5(n), and 6, and four pedoenvironmental units were individualized: Rhodustox domain, Plintustox domain, Rocks domain + Haplustept, and Quartzipsamment domain + Tropsaprent.

KEY-WORDS: Tocantins State soils; agricultural suitability; pedoenvironment; environmental sustainability.
