Consequence of Groundwater Irrigation on Physico-chemical Properties of Soils of Kanholibara Village in Nagpur District, Maharashtra, India

Abstract

A field experiment entitled “Effect of Groundwater irrigation on various soil properties of Kanholi-Bara in Nagpur District Was conducted during Kharif season of 2015-2016 at Kanholi-Bara of Hingana tahsil in Nagpur District Maharashtra, India. The soil samples were collected from that area comprises two source of irrigations viz well water and bore well water and soybean crop which were taken in these fields. The mean value of pH 7.79 was recorded with ground water irrigation and EC in groundwater irrigated soil 0.81 dS m-1.The organic carbon contains in ground water irrigated soil with high Sodium Absorption Ratio (SAR) and Residual Sodium Carbonate (RSC) was lower by 35.19 per cent less than mean value of organic carbon. The lowest available nitrogen, phosphorus and potassium status were 185.44, 15.65 and 178.80 kg ha-1 respectively were obtained with the application of ground water of high RSC and SAR. Whereas the highest accumulation of heavy metal in soil 1.16 mg kg-1 lead, 1.30 mg kg-1 Cobalt, 1.19 mg Kg-1Nikel and 0.037 mg kg-1 Cadmium were present in soil with the application of high SAR and RSC irrigation water. Due to continuous and injudicious irrigation with poor quality groundwater adversely affect the physical and chemical properties of soil.
