Soil management in the Atlantic Forest’s rural properties:

Abstract

The environmental benefits arising from the interaction between matter and energy flows of permacultural systems acceleratethe recovery processes of degraded areas, which can be potentiated by the increase of plant biomass associated with thegreen manure technique, proposed in this work for the study territory: the surroundings of two Conservation Units (UC),of the Private Reserve of Natural Heritage (RPPN) type, the RPPN Águas Claras I and II. The RPPN Águas Claras I andII are located in the Macabu River basin, a microbasin of the Carukango River. The objective of this study was to analyzeareas submitted to reforestation and agroforestry system (SAF) projects, through estimates of local biomass obtained withthe aid of secondary data from the UCs’ forest inventory. As a result, it was possible to list Ficus sp and Sparattospermaleucanthum as priority native species for forest restoration. It was concluded that it is necessary to consort the two specieswith the planting of species considered green manures, in order to increase forest biomass and stimulate the improvementof soil conditions in the degraded portion of the reserve. This strategy can accelerate the regeneration process, as indicatedby secondary soil analysis data using scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDS),performed in the area of implementation of the SAF.
