Strategies and methods for improving phosphorus acquisition and its use efficiency: A review

Abstract

Phosphorus (P) is considered an essential nutrient for all and is also essential from global food security point of view but it is a limited, non-renewable nutrient resource, making its use vitally important. Nowadays, lower productivity in phosphorus availability is major concern. The decreasing ores and suboptimal levels of plant available phosphorus (P) can lead to lower yield. Its interaction with several other plant nutrients makes it very hard for plant availability. Several approaches have been tried and tested and many of them have been found effective, sustainable and cost efficient. However, the need for novel approaches for better phosphorus acquisition like physiological manipulation, better root structure and genetic alteration will help for resource conservation and is environmentally sustainable. But to diagnose environmental impact on excess use of phosphate fertilizers more improvement is required in order so that limited phosphorus stocks can be managed. Thus, there is a need for integrative approach to solve the lower P in soil system.
