摘要

Soils vary widely in their capacities to supply phosphorus (P) to crops because only a small fraction of the total P in soil is available to crops. Thus, the crop growth and yield are likely to suffer adversely unless soil is endowed with adequate native supply of plant-available P, or else the soil receives readily available (inorganic) P fertilizers. In order to rationalize fertilizer P application to support sustained high productivity on one hand and address the environmental and economic concerns on the other, an in-depth understanding of native P supplies and P dynamics in soil is inevitable. In this context, the present article takes stock of the available information on the occurrence of P in soils, chemistry of P in soil, P quantity, intensity, and buffer capacity attributes of different soils vis-a-vis the P uptake modelling, P dynamics in soil, P management in important cropping systems for enhancing its use efficiency, soil testing for plant-available P to prescribe fertilizer P application and losses of P through erosion and runoff to the water bodies leading to eutrophication.
