Physiochemical Parameters Analysis to Get an Upgraded Composting System

Abstract

Physicochemical determinants parameters were analyzed in different stages of organic matter decomposition, using various chemical and biological treatments: Manure, Legumes, Mineral solution, and Vermicompost. Specifically, we studied the importance of decisive physicochemical parameters for obtaining an improved composting system. To do this, were used different techniques, such a C/N ratio, pH, organic matter content, atomic absorption to determining concentration of several mineral, ashes quantification for moisture content and temperature measurement. The vermicompost was the most effective treatment for decomposition of matter, achieving speed up the composting process just 35 days, accounting for 5 months the minimum estimated time to have a complete degradation using a conventional composting system, this represents a decrease of 23.3%, values obtained mainly from C/N ratio were close to 25:1 (25%), a final pH of 8.2, a percent of organic matter lower than 48%, and a concentration of minerals and heavy metals within the norm.
