For nitrogen analysis first and second soil samples were collected around the power plant and sponge iron plant of Siltara area, the third soil sample taken from crop area around rice mill of Bemetara district (India). Samples were collected from 15 cm. depth during post monsoon 2018. Result of chemical analysis of these samples indicates that the soil sample is found to be nitrogen deficient. Sample collected from 50 to 4500 meter around rice crop field. Available N content was raised continuously from 221.79 kg ha -1 (50 m) to 293.42 kg ha -1 (4500 m.) around sponge iron industry, 233.11 kg ha -1 (50 m) to 302.13 kg h -1 (4500 m) around power plant industry and 200.70 kg ha -1 at 50 m and 335.23 kg ha -1 at 4500 m around rice mill industry. This analysis is done by Nitrogen Auto Analyzer. Maximum value of nitrogen with phosphorus - potassium uptake observed in 150 kg of N ha -1 which is available in five split as 6S (10:10:10:20:05 at 11-13, 10, 30, 50, DAS & FL) and the concentration of higher soil available nitrogen also observed in 150 kg of N ha -1 described in following five split as 6S (10:10:10:20:05 at 11-13, 10, 30, 50, DAS & FL), maximum soil available phosphorus - potassium was observed in following three split as 1S (10:40:20 at 0, 20, 50 DAS) applied in 100 kg of N ha -1 .
