Fertilizer is a substance added to soil to improve plants' growth and yield. Fertilizers typically provide, in varying proportions, the three major plant nutrients - nitrogen, phosphorus, and potassium, the secondary plant nutrients like calcium, sulfur, magnesium and sometimes trace elements or micronutrients like iron, zinc, copper and molybdenum. The long term use of Fertilizers damages the soil texture & pH, soil structure and decreases beneficial soil microorganism.

Biofertilizers are based on materials of vegetable, animal and microbial origin which contain certain macro, secondary, or micro nutrients that can be utilized by plants after application to agricultural soils. Use of such biofertilizers in cultivation will help in safeguarding the soil health and also improve the quality of crop products.
