CAUSES OF LAND DEGRADATION

▪️ QUALITY OF IRRIGATION WATER :
The ground water of arid regions are generally saline in nature. The irrigation water may be itself rich in soluble water and add to salinity of soils.
▪️ EXCESS USE OF FERTILIZERS :
Excess use of alkaline fertilizers like sodium nitrate, basic slag, etc. may develop alkalinity in soils.
▪️CAPILLARY ACTION :
Salts from the lower layers move up by capillary action during summer season and are deposited on the surface of the soil.
▪️POOR DRAINAGE OF SOIL :
Salts dissolved In Irrigation water accumulate on the soil surface due to inadequate drainage, especially during flood.
▪️SALTS BLOWN BY WIND :
In arid region near the sea, lot of salt is blown by wind and gets deposited on the lands.
▪️. WATER -LOGGING :
Excessive irrigation and improper drainage facility in the fields cause rise in the ground water level.


The following measures can help to solve the problem of land degradation
(i) Afforestation over deforested areas.
(ii) Proper management of grazing on permanent pastures.
(iii) In areas where, desertification has taken place, growing thorny bushes.
