The population of India crosses 1000 million people. It is estimated that the population will reach 1400 million by 2025, requiring 300 million tonnes of food grains and the increase in production will have to come from higher yields. In order to reach the required yield levels, the use of fertilizer will need to increase and improve. In this review paper we discuss the effect of an organic and inorganic fertilizers on the soil physio-chemical and biological properties. The efficiency of fertilizer use could be improved through combined use of organic and inorganic fertilizers that include an application of macro-nutrients and micro-nutrients according to crop requirements. The excessive use of inorganic fertilizers effect the soil properties at very high rate. The use of inorganic fertilizer is extreme in major agricultural states like Punjab and Haryana where NPK use ratios are very high. India’s Chemical Fertilizers: nitrogen, phosphorus and potassium consumption per hectare in all India data was reported at 133.120 kg per hectare in 2019. This records an increase from the previous number of 127.880 kg/ha for 2018. The organic fertilizers help to increase soil fertility and quality as compared to inorganic fertilizers. A literature search revealed that application of NPK plus pig manure is the preferred option to enhance SOC accumulation, improve soil fertility and quality, and increases yield of crop.
