Impacts of Different Aeration Modes on Nutrients Conservation During Swine Manure Composting with Magnesium Salt Addition
不同通风方式对添加镁盐后猪粪堆肥过程中氮磷保存的影响

Experiments were carried out to investigate the effect of two aeration modes on nutrients conservation in the thermophilic stage of swine manure composting with adding magnesium chloride.These results indicated that in the end of thermophilic stage of composting,the ammonia nitrogen losses of the piles with the intermittent aeration and with continuous aeration,were 23.56 g and 56.98 g,respectively,which means the loss of ammonia nitrogen of swine composting by the intermittent aeration was just 41.35% of t...
