Impact of Water Quality on Soil under Drip Irrigation

This book explores the impact of saline water on soil moisture and salt distribution under drip irrigation, based on a field experiment at the College of Agricultural Engineering and Technology, Godhra, Gujarat. The study analyzed three plots irrigated with water of different salinity levels (1 EC, 2 EC, and 3 EC) using 2 lph emitters. Soil samples were collected at various depths and intervals to measure moisture and salinity distribution. Results revealed that soil salinity patterns depended on water quality and moisture distribution, with higher moisture levels in deeper soil layers. Saline water irrigation created distinct zones of salinity, with higher salt concentrations near the dripper at the surface. Over time, salt accumulation in the soil profile may occur, necessitating periodic heavy rainfall or alternative irrigation methods to prevent long-term soil salinization. This study underscores the need for strategic irrigation management when using saline water to maintain soil health and crop productivity.
