Abstract:
The global availability of phosphorus (P) is limited and hence strategies to judiciously utilize this scarce resource is critical for sustainable agriculture development. An overview of various methods to estimate soil P have been presented systematically and the importance of indicator choices and establishment of interpretation thresholds. Thus for developing long-term P management strategies, it is important to ascertain the forms and characteristics of P remaining in the soil after repeated P fertilizer additions over a period of time in an agro ecosystem. A critical evaluation of P content accurately with reliable indicators is the starting point for P management strategy. The changes in available and different fractions of P due to long-term continuous P fertilization besides its effect on yield are discussed. This study summarizes important research understandings on the impact of long-term application of manures and fertilizers under different cropping systems both around the world and specifically in India.
