WATER LOGGING AND PROBLEMS OF SECONDARY SALINITY IN THE IGNP COMMAND AREA

Abstract

The expansion of brackishness and waterlogged condition in the Indira Gandhi Nahar Pariyojana (IGNP) operating region poses a significant challenge. Factors such as high temperatures, exaggerated aqua-miscible salts in the soil, and excessive desiccation-transpiration have led to secondary salinization and the accumulation of salts on the soil surface and in subsoil layers. The subsistence of impermeable stratum, coupled with the lack of superficial water evacuation outlets, has contributed to a rising water table, resulting in waterlogging. The persuasiveness of inundated cultivation in the IGNP region is at risk due to the progressive increase in soil salinity. Over time, the grieved land has metamorphosed unsuitable for cultivation. There is an urgent need for budget-efficient, enduring pacification initiatives and strategies to maintain fertility and caliber of soil in this inundated arid zone.
