Soil Fertility and Nutrient Management

Abstract

The level of productivity of a cropping system is determined primarily by the interaction of crop genetic potential, environmental factors, and management options. Maintaining an adequate supply of mineral nutrients to crops is one of the most vital requirements for sustained crop growth and productivity. The chapter discusses several aspects of these factors and their interplay in maintaining optimal crop production. Specific importance in the chapter is also given to the role of organic matter in maintaining good soil fertility vis-à-vis ensuring good and healthy soil structure.
