Aptidão agrícola e impactos dos usos da terra na comunidade rural lagoa grande, município de Corrente - PI

Abstract

Inadequate soil management practices associated with inappropriate crops in relation to their potential use have favored the occurrence of significant impacts to the environment. Land use must therefore be planned and controlled to maintain productivity and conservation of natural resources. Thus, the objective of this work was to evaluate the agricultural suitability of the soil in the Lagoa Grande community, in the rural area of the municipality of Corrente - Piauí. The method used was the land appraisal system recommended by EMBRAPA Solos, in which three types of management were adopted, according to the technological level used. In the survey, the factors of limitation were taken as the basis for the evaluation of the agricultural conditions of the area: fertility deficiency, water deficiency, excess water, susceptibility to erosion, and impediments to mechanization. The area presents a primitive management system, mainly depending on the manual work, with small agricultural implements. The results indicated a high agricultural potential, favored mainly by good soil and relief conditions, with low presence of stoniness and absence of erosive processes.
