CHEMICAL SOIL ATTRIBUTES UNDER DIFFERENT SYSTEMS OF USE AND MANAGEMENT IN THE SEALING PROJECT VENEZA - SÃO DOMINGOS DO ARAGUAIA, PA

Abstract

ABSTRACT: In the Amazônia, edaphoclimatic conditions tend to present limitations on agricultural practices due to soil management or natural conditions. The objective of this work was to analyze the soil properties submitted to different managements in the family farm of the Veneza Settlement Project in the municipality of São Domingos do Araguaia - PA. The methods used to carry out this work consisted in the collection of soil samples for the evaluation of soil fertility and a descriptive survey with the farmer with walks on the property to characterize the pasture area, Permanent Preservation Area (APP) and in capoeira environment. The pH of the secondary forest and APP are at the high acidity level and the pasture with medium acidity, and the base saturation is low for both areas. The area of APP showed higher organic matter content as well as P and Mg, however, the value of P considered low and the value of Mg medium. However, the soil cover as well as the adopted management interfere significantly in the chemical properties, as well as in the fertility of the soils. KEYWORDS: Texture, Fertility, Acidity.
