Soil test based fertilizer recommendation for targeted yield of crops: A review

Abstract

This paper reviews the recent scientific investigation carried out in various parts of India on soil test based fertilizer use for achieving the targeted yield of crop. Soil testing has been accepted as a unique tool for rational fertilizer use. It helps to assess the soil fertility status and recommend suitable and economic nutrient dose through chemical fertilizer and organic manure for different crops and cropping system. The selection of proper rate of plant nutrient addition is influenced by knowledge of nutrient supplying power of the soil and efficiency of fertilizers. Fertilizer recommendation based on soil test have been evolved for many crops and cropping system using post-harvest soil test value.
