My enquiry is from Salinity and Water-logging in division Water Logged Reclamation and Saline Soils for Agricultural Purposes of Irrigation Engineering

Answer 1

The correct choice is (a) the aeration is stopped in the root zone due to the rise in water content

The explanation: A land is said to be water-logged when the productivity of land gets affected and the crop root-zone gets deprived of proper aeration due to the flooding or high water table. It represents a saturated condition of the soil especially that of the crop root-zone with water. It also leads to the salinity of the soil.
