By adding additional urea to regulate the C/N of different piles, a non regulated C/N experimental group and a urea regulated C/N experimental group were set up. During the composting process, multiple indicators such as temperature, pH value, EC value, organic matter content, total nitrogen content, and C/N value of different piles were measured to evaluate the progress of the composting process of garden and forest green waste and its degree of maturity. The aim is to explore the feasibility of directly composting landscaping waste and the role of regulating C/N in the composting process of landscaping waste.
