NOVELTY - Fertilizer comprises 5-10 wt.% bacterial liquid and organic-inorganic mixture comprising 15-25 wt.% urea, 5-13 wt.% diammonium phosphate, 4-8 wt.% calcium-magnesia phosphate, 12-20 wt.% potassium chloride, 35-45 wt.% carbon, 0.5-1.5 wt.% zinc sulfate, 0.2-1 wt.% copper sulfate, and 0.2-1 wt.% manganese sulfate. The bacterial liquid is prepared by fermenting Bacillus laterosporus having CGMCC NO: 5090 and B.subtilis having CGMCC NO: 5091, and mixing the bacteria in equal proportion.    USE - As fertilizer for corn plants.    ADVANTAGE - The fertilizer is required in minimal amount as compared to existing chemical fertilizer and stable, and supplies rich nutrition.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for method for preparing the fertilizer, which involves (a) (i) preparing microbial bacterial liquid by incubating B.laterosporus and B.subtilis at 30-38 degrees C under dark conditions for 36 hours, (ii) preparing bacterial suspension using sterile water, (iii) incubating the mixture at 30-38 degrees C, where the the cell culture has 108 cells/ml, (iv) adding 5-10 times bacterial suspension to the culture medium and incubating the mixture at 30-38 degrees C, (v) inoculating the culture in culture medium, fermenting the culture at 35-38 degrees C, passing oxygen while incubation and terminating fermentation, where the fermentation medium comprises 5 g/l peptone, 5 g/l sodium chloride, 5 g/l beef extract, and 1.5-2 wt.% agar, adjusting pH of the mixture to 6.5-7.8, preparing new liquid medium comprising 5 g/l starch, 1 g/l cane sugar, 0.2 g/l yeast extract, 2 g/l peptone, 5 g/l beef extract, 5 g/l ammonium sulfate, 0.5 g/l potassium dihydrogen phosphate, 0.2 g/l magnesium sulfate and 5 g/l sodium chloride, preparing tertiary culture medium having pH of 6.5-7.8 comprising 10 g/l starch, 5 g/l sucrose, 0.1 g/l yeast extract, 0.5 g/l peptone, 10 g/l bean cake powder, 1 g/l ammonium sulfate, 0.5 g/l monopotassium phosphate, and 5 g/l sodium chloride, preparing quarternary culture medium comprising 10 g/l starch, 2.5g/l sucrose, 0.1 g/l yeast extract, 0.5 g/l peptone, 5 g/l bean cake powder, 1 g/l ammonium sulfate, 0.5 g/l potassium dihydrogen phosphate, and 5 g/l sodium chloride, (vi) fermenting the mixture, heat drying the bacterial liquid, and sterilizing the heat-dried liquid using toner, and (b) adding remaining dry urea, diammonium phosphate, potassium chloride, calcium magnesium phosphate, zinc sulfate, copper sulfate and manganese sulfate, crushing and blending the mixture, drying the mixture at low temperature, and pelletizing and packaging the pellet.
