Análise do processo de produção de um composto a base de resíduos vegetais e estrumes de animais

Abstract

The mastery of the composting process and the knowledge of its chemical and microbiological characteristics define the wide applicability of the product resulting from this process (compost). It is one of the solutions for the reduction of many problems that affect the environment in general and the agricultural part in particular. The present work aims to understand the process of producing a compost based on the use of plant residues and animal manure available in rural areas; identify process maturity indicators and analyze factors that affect the compost production process. In order to reach the objectives outlined, five cumulus clusters were set up which differed proportionally in terms of lignocellulosic material (corn) and nitrogen content (chicken manure, cowpea and urea). The main results show that proportional differences in terms of materials that were part of the cumulus clusters determine the greater or lesser stabilization and quality. The results also show that the humility content defines the environment in which the process takes place and the temperature evolution is directly related to the biodegradation of the substrate. The main conclusions of the study point to temperature and humidity as the main factors that affect the process. The efficiency of the process depends on the nature of the materials involved and the time of execution. The conclusions also show that the main indicator of the maturity of the compost is the physical aspect (texture and color).
