Soil Conservation

Soil

• The upper layer of earth in which plants grow.

• A dark brown material consisting of organic remains & rock particles.

Soil Conservation

Different managment practices utilize to protect soil from being washed by eroding agents (water & Wind).

Why is soil conservation important?

• Provide nutrients• Recycle/filter water• Stores water• Soil is the basis of life on Earth• Plants get nutrients from soil and

provide glucose & oxygen.

First let us look at the problem of soil erosion.

Sheet erosion is the removal of the thin layer of topsoil by raindrop splash or water run-off.

First let us look at the problem of soil erosion.

Wind erosion is the detachment and movement of soil by wind.

First let us look at the problem of soil erosion.

Gully erosion occurs when small streams unite and create a stronger flow, cutting a channel down which water flows during or just after rain.

Worldwide, an estimated 26 billion tons of topsoil are washed or blown off cropland each year. Every year 6 million hectares of productive dryland become desert.

What can be done to save our soil? The most critical factor

in protecting soils from erosion by water and wind is the maintenance of cover (plant residues, pasture and forests) in close contact with the soil surface.

The Importance Of Groundcover

Improve Soil Management• Practice:* Contour plowing,* Reduced tillage or no

tillage, * Using windbreaks to

reduce wind speeds at the land surface,

* Promote humus production.
