Delayed nutrient application affects mineralisation rate during composting of plant residues

摘要: The hypothesis that delayed addition of nutrient rich material to compost would influence the mineralisation pattern was investigated by studying N turnover in based on wheat straw and clover-grass hay. After 712 weeks composting almost twice as much mineralised when some N-rich hay postponed, suggesting this influenced microbial succession. resulted a second temperature peak decline pH. Despite altered conditions no significant effect observed weight loss or C N. In conclusion, processes can simple way be affected substrate application leading higher availability without altering other parameters significantly.
