Effects of aerobic composting on transformation of rock phosphate
好氧堆肥对难溶性磷转化的影响

Organic acid substances produced during dairy manure (DM) composting could transform rock phosphate.The effects of composting on increasing rock phosphate solubility were studied by mixing ground phosphate rock into DM during the composting process.Compared to DM treatment,P1DM treatment increased the active organic phosphate by 120.99%,moderately active organic phosphate by 34.86%,moderately stable organic phosphate by 27.74% and highly stable organic phosphate by 21.38%.Treatment with P2DM increased the a...
