The topography is flat

The culturable waste of DIKhan

with reference to soils are

Gully erosion most commonly

observed in the south western

parts of DIKhan .

hardpan is formed and very

difficult to apply normal ploughing

The land is occupied by local people

and no soil conservation practices were

adapted by them.

Sheet erosion

Removal of thin layer of fertile soil and reduces the nutritional status of the soils

Observed throughout DIKhan but in patches

Wajid Ali (2010) Wajid Ali (2010)

Conservation Techniques To Reduce Erosion

To prevent existing gully erosion or gully plugs using sticks or branches or using

flat stones with active participation of local community.

Conservation Techniques To Reduce Erosion

To prevent existing gully erosion or gully plugs using sticks or branches or using

flat stones with active participation of local community.

Conservation Techniques To Reduce Erosion

To prevent existing sheet erosion required shelter belt of trees and grasses

should be grown between the crops to act as barriers

Traditional methods to reduce soil erosion

Mulching
