The study looked at how adding wheat straw to sheep manure affects the composting process. The researchers found that adding wheat straw can speed up the high-temperature composting of sheep manure, reduce nitrogen loss, and help balance the carbon-to-nitrogen ratio. During composting, the high-temperature fermentation layer spreads from the middle upwards and downwards. The content of phosphorus, potassium, and nitrogen in the compost increased by the end of the process, with the 6:4 ratio of sheep manure to wheat straw showing the highest increase. Composting sheep manure with wheat straw in a 6:4 ratio is the most effective, with compost reaching maturity in just 28 days.
