waterlogged land Waterlogging is an effect of canal irrigation; it occurs when the water table rises to within 3 meters of a crop's roots, impeding their ability to absorb oxygen and ultimately compromising crop yields. Many factors contribute to waterlogging. These include inadequate drainage, improper balance in the use of groundwater and surface water, seepage and percolation from unlined channels, overwatering, planting crops not suited to specific soils, and inadequate preparation of land before irrigation | |
