It is the component of overall soil productivity that deals with its available nutrient status, and its ability to provide nutrients out of its own reserves and through external applications for crop production. Thus a fertile soil may or may not be productive depending upon crops, marketing condition and several other factors (i.e. Soil management controls the supply of nutrients to crops, and 22 subsequently to livestock and humans.
