Soil Conservation -

It is defiend as the control of soil erosion. 

In order to maintain agriculture productivity.

In oth word soil erosion is defiend as a process of detachement transport fusion sediments of soil particle. 

Sediment :- 

It is defiend as any fragmental material which is transported or deposited by water Ice, air or any other natural agent. 

some land degradation problem due to sedimantaion. 

Erosion by wind & water. 

Formation of Gullies & Ravines. 

Water Logging 

Flood and Drought 

Saline soil 

including coastal areas

Shifting Cultivation 

Casues of soil erosion 

1. Destruction of natural protective cover 

2. Cultivationof trees 

3. Overgrazzing of vegetative cover, forest fire. 

Improper use of land. 

Keeping the land barren subjecting it to action of rain and wind

Growing of crop that accelerate soil erosion 

removal of organic matter and plant nutrition by improper cropping pattern. 

Cultivation along the land flow. 

Faculty method of Irrigation.
