Changes of Physicochemical Properties and Maturity Evaluation of Cassava Residue Compost during Composting
摘要
Abstract
Cassava residues were composted at high temperature, and their physicochemical properties and compost maturity were observed during composting process. The results showed that the temperature tended to increase and then decrease during composting and fermenting, and that the moisture content of the compost varied little during the composting process. The pH value of the compost treated with additional nitrogen was about 8.5 when the fermentation of the compost came to the end. The content of water-soluble carbon (WSC) in the compost decreased with composting, reflecting the maturation process during cassava bark composting. The content of water -soluble nitrogen (WSN) of the compost was considerably affected by ventilation and nitrogen source. The cellulase activity showed the trend of "rising-descending" in all the composts. Compost maturity can be explained effectively and reliably by seed germination rate. Composts fermented for 24～30 days are not toxic to plants.关键词
