Question

How Over irrigation causes land degradation​

Answer 1

Answer:

It leads to reduced aeration, nutrient uptake, and crop yields. Salt buildup occurs through the process of capillary rise when the water table rises close to the surface. Salinity risks also increases when saline water is used for irrigation and when poor fertilizer and poor irrigation management are combined.
