THE NUTRIENT POTENTIAL OF ORGANIC MANURE AND ITS RISK TO THE ENVIRONMENT

The livestock sector is an important component of agriculture that involves the breeding of various types of domestic animals. Although animal husbandry is a key activity in global food production, providing food for human society, income, jobs, nutrients, etc. it also has negative consequences, being the second largest polluter after the power industry. An important issue related to the livestock sector is manure produced by animals. The purpose of this paper is to understand the potential of organic manure nutrients as well as the negative effects they can have on the environment. In order to carry out the study, investigations were required regarding the calorific value and the elementary analysis (C, N, H, S, O) for five different types samples of manure from: poultry, sheep, cow, horse and pig. All types of manure have a moisture content of between 40-60% and can be used for composting. With manure we can produce biogas, but is necessary to know the correct way of managing manure in order not to lead to pollution
