摘要

This study investigates the global issue of organic waste, driven by expanding agricultural activities, focusing on managing sheep manure through composting. The experimental monitoring took place over seven months near Casablanca, Morocco. A specialized company produced the compost, using windrow composting with sporadic mechanical rotation. Temperature, moisture, pH, conductivity, organic carbon, nitrogen, and nitrates were monitored. During the thermophilic phase, compost windrows reached high temperatures, peaking at 73 °C. The resultant compost had a nearly neutral pH (7.02), moderate organic matter (26.19%), elevated nitrogen levels (1.961%), and an optimal carbon-to-nitrogen ratio (13.29). Maturity indicators, such as Cation Exchange Capacity (CEC = 67.03 meq/100 g) and the CEC-to-Organic Carbon ratio (CEC/OC = 1.95), suggested humification and maturity. Additionally, the compost contained essential macro- (calcium, sodium, potassium, and magnesium) and microelements (iron, copper, zinc, and manganese) that enhance soil quality and crop development. These findings offer significant potential for sustainable agriculture in Morocco, particularly for farmers seeking to enhance soil productivity and livestock rearing. The recommendations include exploring various compost application methods in agriculture and advocating for heap composting, especially in the cattle industry. In essence, this study demonstrates how efficient organic waste management can bolster agricultural productivity and environmental sustainability.
