摘要

Crop phosphorus(P)deficiency and poor utilization of added P is a major agricultural problem due to reduced solubility of soil P and rapid fixation or precipitation of applied P fertilizer in alkaline and calcareous soils.The effects of P-enriched compost and single superphosphate(SSP)fertilization on maize and wheat yields and P use efficiency in a maize–wheat rotation system were studied for three years.On a three-year average,grain yields of maize and wheat after application of P-enriched compost were increased by 18%and 24%,respectively,in comparison with sole addition of a recommended dose of SSP fertilizer.P-enriched compost addition to soil increasedmaize and wheat yields by 12%and 17%,respectively,compared to P fertilizer plus FYM incorporation.Soil available P concentration and P uptake were affected significantly by the addition of P-enriched compost.On average,increases in P recovery,use efficiency,and agronomic efficiency of 52%,18%,and 43%were recorded in maize and increases of 50%,23%,and 49%inwheat.P-enriched compost application yielded 30%and 32%higher economic returns in maize and wheat than SSP fertilization alone.
