Description

Addressing the global spike in organic waste, worsened by rising agricultural operations, is critical in the context of escalating environmental issues. The danger of non-point source contamination grows with improper handling of organic waste. This study emphasizes the need of thorough monitoring as a remedy across the composting process. This research focuses on organic waste management, with a particular emphasis on sheep manure composting. To guarantee successful waste management, it employs an experimental technique to monitor the composting process and examines several physicochemical characteristics. An experimental approach was used to monitor the composting of organic waste from sheep manure. Over the course of seven months, sheep manure and straw bedding obtained from a supermarket in Casablanca city supermarket were composted. The materials were sorted and cleaned from plastic, cardboard and glass and then well mixed using a bucket loader. The compost was produced by using the windrow composting method with a periodic mechanical turning. The examination took place on the grounds of a specialized compost producing company, which offered a suitable environment for the experiment. Throughout the procedure, variations in temperature in the various composting zones were noted, and samples were collected and taken periodically to the laboratory for physicochemical analysis. A variety of macro and microelements as well as evaluations of moisture, pH, conductivity, organic carbon, nitrogen, and nitrates were all included in the physicochemical examination. To ensure effective pathogen eradication and secure composting, the thermophilic phase of the composting process reached a maximum temperature of 73°C. The final composts had a pH that was virtually neutral (7.02), little organic matter (26.19%), more nitrogen, and an ideal Carbon to Nitrogen ratio (13.29), all of which pointed to stability. Capacity Exchange Capacity (CEC=67.03 meq/100g) and increasing CEC to Organic Carbon (CEC/OC: 1.95) were indicators of humification and maturity. The resulting high-quality compost contains important macro and microelements, which improve crop development and soil quality. This investigation underlines the significance of sanitary methods in producing safe and nutrient-rich compost. These discoveries hold great promise for sustainable agriculture, especially for Moroccan livestock producers and farmers looking to increase soil production. In addition to encouraging heap composting in the livestock sector, recommendations include researching various compost application methods in various agricultural situations.
