Abstract:
Acid soils are very prone to the losses of clay particles, nutrient and organic carbon. It is well saturated with sesquioxides. All these factors are greately harmfull to the soil fertility, and use efficiency of the water and nutrient particularly N, P, S and some micronurients. Many researchers have tried well to find out the effects of soil constraints on the efficiency of the nutrients in acid soil. They has also suggested for its remady. Soil test based fertilizer application is highly beneficial for enhancing use efficieny of the nutrient and keeps the resource healthy for ever. Other has suggested that liming as well as ample supplementation of the soil organic matter (SOM) more beneficial and sustainable not only to the soil but also for crop and environment. These two inputst increases nutrient use efficiency very much. Liming is beneficial for quick resolution of the soil acidity whereas SOM is slowly effective but permanent solution of all the problems associated with the acid soil. Fertilizer use efficiency can be optimized by fertilizer best management like proper rate, time, and place of uses has also been suggested. Various traditional methods such as halting of sheep and other techniques of soil restoration also have been suggested. The highest nutrient use efficiency always occurs at the lower parts of the yield response curve, where fertilizer inputs are the lowest, but effectiveness of fertilizers in increasing crop yields and optimizing farmer profitability should not be sacrificed for the sake of efficiency alone. Nano fertilizers are the important tools in agriculture to improve crop growth, yield and quality parameters with increase nutrient use efficiency, reduce wastage of fertilizers and cost of cultivation. There must be a balance between optimal nutrient use efficiency and optimal crop productivity.
