Qualidade do solo na área de mandiocal com a utilização de cobertura de restos vegetais no Sítio Agroecológico de Produção Orgânica, do Assentamento Perpétuo Socorro, Nova Ipixuna - Pará

Abstract

Soil is a fundamental component of the terrestrial ecosystem, as it is the main substrate used by plants for their growth and dissemination, providing the roots with growth factors such as water, oxygen and nutrients. Soil characterization is essential for soil cartography, as it allows to establish correlations between soils found in different regions of the globe and their physical, chemical and biological needs. Based on these concepts, the work aims to evaluate the physicochemical quality of soils in cassava cultivation areas before and after the implantation of the crop with the use of green cover in the soil in a family farm in the settlement, Perpetuo Socorro, located in the Southeast region of Pará. The soil was classified as a sandy loam soil with acidity. The positive differences occurred in the maro and micronutrient contents between the first and second samples are directly linked to the practices of incorporation of cover with vegetal remains used in the period of cassava cultivation. In spite of the positive variations, some analyzed nutrients presented low levels in relation to the reference values used, evidencing a low fertility soil.
