Vast areas have been depleted of the fertile top soil due to the siltation and salinization mainly attributed to floods. Crops yield have been much reduced. Besides we have come across the various effects caused due to the fast removal of the vegetational cover and massive deforestation in all almost regions of the world .The consequences are well known to all of us. Besides depletion in forest production, a number of ecological changes such as reduction in the quantity of water in the Groundwater (Aquifer) as well as drastic changes in the environmental quality and climate are concomitant. The reason which is quite obvious of the reduction in the production of the crops and tress is the degradation and destruction of the soils. The erosion and depletion of the fertile top layer of the soil are caused by a number of factors such as unscientific agricultural practices, construction of large dams, massive deforestation and number of man's activities concerned with overcultivation, urbanization and industrialization etc. All these activities denude the land of its protective green cover, hastening the process of soil erosion, degradation water logging and salinity. This affects both the cultivated and uncultivated lands. When these problems are not checked in time by taking proper remedial measures, there is every likelihood that the soil might lost its fertility forever turning the same into a barren land and desert.
