Question 1 Report

Water-logged soils impede good crop growth and development because
Answer Details
Water-logged soils impede good crop growth and development because crop roots are deprived of sufficient oxygen. When the soil is water-logged, the spaces between soil particles become filled with water, which displaces the air in the soil. Roots need oxygen to respire and to convert sugars into energy for growth, so without it, the roots cannot function properly. As a result, the crop may experience stunted growth or even die.
