Detailed Solution

Over-irrigation is one of the major causes of land degradation in Punjab as it increases the alkalinity and salinity of the soil. Irrigation becoming predominant in India is not new, but after the introduction of fertilisers and pesticides, the use of irrigation has increased a lot. Irrigation means aiding the soil for better growth of the crops, but when this irrigation is done at a large rate over a piece of land, it increases the alkalinity and salinity of the soil and damages the other areas of the soil as well. It is one of the major reasons why soils are losing their fertility.
