Study on Packing Materials for High-temperature Compost of Livestock Manure

摘要

Packing materials made of organic or inorganic substances can improve the composting speed or increase the compost quality. Pilot experiments on outdoor composting were carried out to investigate the effect of packing materials on nitrogen losses and compost quality. The results showed that both furfural dreg and mushroom dreg can be used as packing materials in composting chicken manure. Compared with maize straw, furfural dreg and mushroom dreg were more suitable for the industrial-scale production of organic fertilizers. Packing materials can optimize the composting conditions, improve microbial activity, accelerate the composting process, reduce nitrogen losses, and maintain nutrients, thereby improving the compost quality.
