Phosphorus (P) is an essential macronutrient for plant growth and development. Despite the fact that soil contains 1000 times more P than plants do, limited diffusion and a high rate of fixation imply that P is rarely accessible for plant uptake. Therefore, in the absence of Pfertilization, plants are susceptible to P-deficiency, which may result in a 30?40% loss in crop yield. This emphasises how crucial it is to apply a lot of phosphate fertilisers in order to satisfy crop demands. P-fertilizer comes from a limited and non-renewable supply of rock phosphate, which is depleting over time. Furthermore, P resources are being lost as a result of farmers applying P fertilisers sporadically without taking the soil stock into account. The low P-use-efficiency (PUE) of plants under field conditions (15?20%) indicates that the majority of P applied through soil stays unavailable to plants. excess P leads to runoff and leaching that contaminates ground and surface waters (eutrophication), which in turn pollutes the environment. In order to prevent pollution of the environment and ensure the sustainable management of P resources, P fertilisers must be applied while taking the soil test value and PUE into account. Phosphorus solubilising bacteria are highly useful for increasing the plant available P in soil. Technological advancements like fertigation, nano fertilizers, etc. have potential to sustain food grain production.
