EVALUATION OF THE DECOMPOSITION OF THE FOLIAR BIOMASS GLIRICÍDIA (Gliricidia sepium) IN TWO EARTH USE SYSTEMS

Abstract

The litter that occupies the superficial layer of the soil provides great benefits to the soil, acting mainly as soil protector and in the nutrient cycling, providing the return of the elements through the decomposition process. By analyzing the decomposition of leaf biomass in different systems it is possible to quantify the differentiation of nutrient returns from each land use system. The present study aimed to report the procedures performed in the field and laboratory of the decomposition of leaf biomass in two different systems of land use. In the study of leaf decomposition a technique known as litterbags or leaflet bag was used after a certain period of time, the nylon bags were removed and taken to the laboratory of Agroecology of the UFPB, to determine the remaining foliage mass and, At the end of the experiment, the data obtained will be used to measure the decomposition rate of the leaf biomass. It is expected that there will be higher losses in the treatment of the Mandala, because the production unit is subject to continuous agricultural management.
