Appraisal of Soil Salinity in Haryana State by Using Electromagnetic Induction Tool

Abstract

This paper aimed to analyze the soil salinity of the Siwanamal village subsurface drainage site in the Jind district of Haryana. Also, a spatial salinity diagram was applied to observe soil characteristics and controlling constituents of the underground aqua region. In Haryana, more than 50,000 ha area is a waterlogged saline area having a shallow water table at a depth 1.5 m; due to this fact, the natural drainage system is not sufficient for controlling the salinity trouble. Therefore, subsurface drainage (SSD) technology, a synthetic drainage method, is wanted to reclaim waterlogged saline lands in the Haryana region for enhancing crop productivity and controlling the soil salinity. A SSD system is designed to control soil salinity and waterlogging in an affected area. In Haryana, about 10,584 ha waterlogged saline area in nine districts of the state has been reclaimed by SSD technology. In this study, one SSD site (i.e., Siwanamal in Jind district) is selected and measured the soil salinity from Electromagnetic Induction Tool (EM-38) along with the GPS coordinates from Block 3 and 4. Further, it is used in mapping software to develop maps and analyze the status of the selected site. Largest area 64.51% of Block 4 is under moderately saline soil (Ec = 8–16 dS/m) and largest are of Block 3, i.e., 57.28 is under moderately saline soil (Ec = 8–16 dS/m). The area under Ec > 16 dS/m is 1.08% in Block 4 (full pumping) compared to 26.36% area in Block 3 (partial pumping) at SSD site in Siwanamal.
