Abstract:
The soil samples were collected from Bhavalkhera block of the Shahjahanpur district (U.P.) from three depths viz. 0-15 cm, 15-30 cm and 30-45 cm. Twenty seven samples were selected from nine different sites for analysis with the help of completely randomized design. The results revealed that the soil colour changed from Olive yellow to Yellow colour in the dry condition while dark grey brown colour predominant in the wet condition. Soil texture in bhavalkhera was clay loam. The bulk density varied from 1.05 to 1.21 Mg m^-3, particle density from 1.5 to 2.85 Mg m^-3, specific gravity from 1.74 to 2.84. The water holding capacity ranged from 64 to 88%, pore space was 47 to 66%. The pH ranged from 6.45 to 8.20, electrical conductivity from 0.046 to 0.239 dS m^-1. Organic carbon ranged from 0.87 to 1.725% suitable for sustainable farming. Available nitrogen ranged from 202 to 424 kg ha^-1, available phosphorus ranged from 38 to 49 kg ha^-1 and available potassium ranged from 67 to 168 kg ha^-1, all of which showed decreased value with increased in depth. Exchangeable Calcium varied from 1.3 to 1.9 [cmol (p⁺) kg^-1], exchangeable magnesium from 0.9 to 1.6 [cmol (p⁺) kg^-1], available sulphur ranged from 10 to 19 ppm, available iron ranged from 4.5 to 12 ppm, available manganese ranged from 5 to 13 ppm, available copper ranged from 0.2 to 0.8 ppm and available zinc ranged from 0.5 to 1.1 ppm, all of which varied significantly with depth. This study revealed that the untreated wastewater discharged from the sugar industry is found polluted and exceeds the prescribed limits for irrigation and public use.
