摘要：

Organic wastes can be applied to cropland to supply nutrients. Sewage sludge associated or not with mineral fertilization can be applied to improve soil chemical properties. A field study was carried out to investigate the effects of sewage sludge compost application on some chemical soil characteristics and yields of maize and oat. Experimental results showed that similar to literature data, sewage sludge compost application led to increases of mobile phosphorus contents in soil. Addition of mineral N-P fertilizers into composted sewage sludge increased the crop yield. Considering the accumulation of nutriens from organic wastes in cropland soil and their availabilty for crops, sewage sludge compost should be applied to croplandat high rates.
