Impact of Industrial Effluent on Physico-Chemical Properties of Soil in Unnao District of Uttar Pradesh, India

A study was carried out during 2021-22 considering various vegetable growing farmers in Unnao District (U.P.) to find out the effect of using industrial effluents as the only source of irrigation to their crops. 250 surface soil samples collected from farmer’s field were analyzed for physical as well as chemical parameters. The physical properties of soils improved due to industrial effluent irrigation. Among the physical properties bulk density ranged from 1.15 to 1.55 Mg m-3 and particle density ranged between 2.61 to 2.86 Mg m-3. Chemical Parameters of soil such as pH , EC, OC, Available N, P &K were also analyzed and the results indicated that soils had a mean pH of 8.1, E.C. of 1.25 dSm-1, O.C. of 0.756 %, available nitrogen ranged from 377 – 1035 kg ha-1 with mean of 658.26 kg ha-1.The Phosphorus availability was found ranging from 20.5 – 48.80 kg ha-1 with a mean of 35.97 kg ha-1, while Potassium was found with a mean of 204.12 kg ha-1 in range of 163 – 302.2 kg ha-1.
