Abstract: Nature made the soil as a self-renewable natural resource material so far as its fertility is concerned; but, its misuse and overuse, man has disturbed this balance of nature. He has not returned back faithfully what he took from the soil. Basic information on soils has advanced at a tremendous rate, but wisdom in their management, to those who till them, has been slow to come. The result has been rapid decline in soil fertility, fall in yields per acre and insufficient agricultural production in India, particularly so within the last few decades. Fertility in the soil is the result of the presence in it of essential plant nutrients, both major and minor, in adequate amounts and in forms which plants can utilize. In addition, the organic matter in the soil, with its resulting physical and microbiological benefits, is also highly important as it makes the soil a living body. It is necessary to know what the present status of these soil fertility elements is; how they decrease or increase; and what are the ways by which they can be maintained in the forms and at levels which can give high crop production is long-term use. In this paper, an attempt has been made to evaluated the fertility status in watersheds of Kadapa drought prone mandals. Based on fertilize index suggested suitable crops and also required fertilizers for improve the strength of the soil and crop yield.

Keywords: self-renewable, fertility, physical and microbiological benefits.
