Interpretive Summary:

Technical Abstract: World population is projected to increase to about 9 Billion people by 2050. To feed the increasing world population, it is projected that global food supply should be increased by about 60-70% by 2050. Increase in food production could be achieved by improving yield per unit land area, increase land area for crop cultivation and increasing cropping intensity. All these alternatives will require higher inputs of resources such as water, nutrients and other agricultural inputs. Among essential plant nutrients, nitrogen, phosphorus and potassium are most important in determining crop yields because they are required in higher amounts by crops. Phosphorus deficiency is one of the most yield limiting factors in most soils under crops especially on acid soils of temperate as well as tropical climates its is sever. Adaptation of P use efficient cultivars and improved advanced P management practices such as correction of extreme soil pH and adequate amount, proper balance, appropriate timing of application, effective methods of application and nature of P fertilizers will significantly affect in improving crop yields in the future. Phosphorus is the major non-renewable resource where scarcity could significantly affect crop yields in future. Because of the importance of phosphorus in agriculture and because of its limited supplies in most soils, the proposed book will be a timely publication which will discuss advanced efficient management of phosphorus for sustainable crop production.
