Due to the building of the Hydroelectric Power Plant of Ilha Solteira, in the late 60s, some areas have been deforested and were used as “loan areas”. Thus, the soils belonging to these locations were subtracted and these areas’ physical, chemical and biological properties became inappropriate. This work aimed at evaluating the use of chemical and organic fertilization to improve the degraded subsoil and replanting with mycorrhizal Stryphnodendron polyphyllum (“barbatimão”). The area is located at the Experimental Station (FEPE), UNESP/Ilha […]

The inadequate use of soils induces alterations, exhausting the productivity, and resulting in growing areas of degraded soil. This study had the objectives of a) studying alternatives to promote the formation of the A horizon of a degraded soil through the use of green manure, sewage sludge, and cultivation of a native tree species; and b) selecting soil quality indicators to detect the alterations in the surface layer. Evaluations were executed annually. The experimental design was in random blocks with […]
