ATIVIDADE ENZIMÁTICA EM SOLOS ARENOSOS MANEJADOS COM SAF NO PONTAL DO PARANAPANEMA

Abstract

Ecological systems are fundamental to the principles of biodiversity, nutrient cycling, ecological ecosystems and reproduction of dynamics. The objective of the work was used with microbiological parameters to evaluate the quality of agroforestry systems in implantation ages, and to compare them with occupied areas with pastures without management (same use) and native forests, in a total of 5 areas, located in Pontal do paranapanema. The methodology consisted of a bibliographic survey, collections and soil examinations. For each of the selected areas, a grid with 5 random points was defined for collecting soil samples at a depth of 0-10 cm. The offers made were: Dehydrogenase enzymatic activity; Phosphatase activity; ß-glycosidase; Arylsulfatase activity; and FDA. as collected from companies contracted for Unoeste's soil laboratory. The data obtained in the experiments were selected for statistical analysis. As enzymes were shown to change phosphatase and were not significant between treatments, the phosphatase changes observed in the FDA analyzes and the glycoside survey were altered.
