The importance of soil nutrient management for sustainable agriculture has been widely recognized. Soil is the reservoir nutrients and half of the elements in the periodic table are being uptake from the soil by the plants but of these, only sixteen elements are essential. A soil with a Ph of 6.5-7.5 with adequate soil organic matter (about 2 to 4%) will help supply many of these nutrients; however, additional nitrogen, phosphorus and potassium are usually needed for good yields. There is increasing trend of nutrient imbalance in the soil; evident from the fact the amount of nutrient removed from the soil is more than the quantity added in the soil. This nutrient imbalance is called nutrient mining and nutrient mining resulted in poor soil health. Nutrient availability depends not only on soil nutrient store but also on the favourable soil conditions as soil reaction, physical and biological properties. Sound nutrient management is prerequisite for enhancement & maintenance of soil productivity, sustainability of agriculture.
