- Abstract
In Brazil, there are many areas in the degradation and/or degraded stage, in which it is necessary to know the soil properties of these areas in order to help in the decision making of the best strategy to be adopted for their recovery. Thus, the present study aimed to analyze chemical and biological attributes of a soil in areas under different levels of degradation in a desertification core, in the region of Gilbués, state of Piauí, Brazil. The study area is in one of the centers of desertification in the Northeast, located in Gilbués - PI, in the Research Center for the Recovery of Degraded Areas. Four study areas were selected, namely: Native Forest - Area with Cerrado type vegetation; Area under Recovery - Recovery process since 2003, with the construction of small dams and planting of legumes in the same year; Area in Beginning of Degradation - Sparse vegetation, with the presence of an exposed C horizon and a Degraded Area - Absence of vegetation cover and loss of the surface layer of the soil. Soil sampling was performed at random with collections in the layers of 0-0.10 and 0,10-0,20 m. Where chemical and microbiological attributes of the soil were evaluated. The pH and soil organic matter were the variables that most influenced the chemical and biological attributes of the soil, so that both correlated with most of the studied attributes, showing that they are the main soil attributes to be considered when aiming at improvement of soil quality in degraded areas.
