Development of secondary salinity and salt migration in the irrigated landscape of hot arid India

The present paper examines the nature of salt movement by the influence of landscape position and development of secondary salinity in Indira Gandhi Nahar Pariyojana command area of hot arid India. Soil samples were collected along 20 km transect across landscapes of upland, medium land, lowland and...

Description
Summary:The present paper examines the nature of salt movement by the influence of landscape position and development of secondary salinity in Indira Gandhi Nahar Pariyojana command area of hot arid India. Soil samples were collected along 20 km transect across landscapes of upland, medium land, lowland and wetland. Soil properties, electrical conductivity of saturated extract (EC e ), soluble ions in saturated extracts, exchangeable sodium percentage (ESP) and sodium adsorption ratio were determined. Results showed that cation exchange capacity, organic carbon and CaCO 3 were significantly increased in lowland and wetland while soil pH, salinity indicators (EC e and ESP) and exchangeable cations and anions such as chloride and sulphate were increased significantly ( P
