Fertilizers are a major contributor to increased crop production, but the continued and unbalanced use of chemical fertilizers is causing unsustainable environmental problems such as deterioration of soil health, surface water pollution, nitrates of groundwater and air pollution. denitrification of nitrogen and deposition of phosphorus not available in soils are also due to the use of chemical fertilizers. The efficiency of fertilizer use in India is 30-50% for nitrogen, 15-20% for phosphorus and 70-80% for potassium. Above all, the production of inorganic fertilizers is energy intensive, depending on fossil fuels and, therefore, more and more expensive. To address the above situation, Indian agricultural scientists are constantly stressing the use of bio-fertilizers. During 2001-2002, the production and distribution of biofertilizers in the country was approximately 10,000 metric tons, where the production of Rhizobium, Azotobactor, Azospirillum, Acetobactor
and PSB were 1603, 1553, 1258, 166 and 4088 metric tones, respectively. Among other biofertilizers, compost accelerators, such as cellulose / lignin decomposers, are considerable importance.
