Question

dash of soil occurs when irrigations is not accompanied by drainage​

Answer 1

Answer:

Waterlogging is the saturation of soil with water.[1] Soil may be regarded as waterlogged when it is nearly saturated with water much of the time such that its air phase is restricted and anaerobic conditions prevail. In extreme cases of prolonged waterlogging, anaerobiosis occurs, the roots of mesophytes suffer, and the subsurface reducing atmosphere leads to such processes as denitrification, methanogenesis, and the reduction of iron and manganese oxides.[2]

Answer 2

Explanation:

agriculture?

In waterlogged lands, the water table rises to an extent that the soil pores in the crop root zone are saturated resulting in restriction of the normal circulation of air. ... Waterlogging can reduce the agricultural and economic value of land causing yield reductions or at times, total crop failures.
