Sistema Agroflorestal em área degradada: subsídios para recuperação de solos em geossistemas urbanizados

Abstract

The objective of this work is to observe the initial stages of the implementation of an agroforestry system (AFS) in a cambisol, using legumes to recover the top of the degraded soil at the Kamuatá Experimental Station (KES) located on the Faculty of Teacher Training (FFP) campus. Thus, it is intended to monitor the first effects of revegetation on the soil, using climatic and pedological data from the region as a subsidy for the development of the SAF. The work will be developed in three chapters, through which the theoretical basis related to the soil and agroforestry systems, empirical data in an integrated analysis of the study area and the outcome with subsidies for the implementation of agroforestry systems through the Kamuatá experimental station project. The results found after 30 months after the installation of the project, being 10 months of intensive management and 20 months of spontaneous growth, were satisfactory in relation to the increase in species diversity, transformation of the top of the soil, decrease in runoff and enlargement of the crown of the trees. It is concluded that the analyzed agroforestry system was able to produce, through exchanges of energy and matter with the environment, subsidies for the restoration of degraded soil.
