Evolution of the physical and physico-chemical parameters of compost resulting from a mixture of oasis waste and poultry manure

Abstract

The purpose of this study is to monitor the evolution of some physical and physico-chemical parameters of four types of compost prepared from the mixture of oasis waste and poultry manure in different proportions. During the trial, which lasted 218 days, the temperature rises during the thermophilic phase for all the treatments, reaching a maximum threshold of 55°C recorded by the treatment (poultry manure (PM) + mixture of residues (wheat straw + olive residues) (MI)). The pH, EC, nitrogen, phosphorus and potassium values increase for all treatments at the end of the test. On the other hand, the MO content and C/N ratio are significantly reduced during the trial, especially for treatments containing poultry manure. The results obtained show that the four prepared composts meet the characteristics of a stable, hygienic product suitable for use in poultry farming.
