All the plant family, animal kingdom and human society at large depend upon soil for their sustenance directly or indirectly.

Ironically, soil conservation essay, soil is the most neglected commodity on the earth. It will take hundreds of years to form an inch of soil, soil conservation essay, but in no time it gets washed away down the slope due to erosion.

So conservation of soil is essential for sustenance of human life on the earth. Generating additional soil conservation essay opportunities and income through secured livelihood in rural areas. Retarding Watershed degradation caused by deforestation, soil erosion, soil conservation essay, sedimentation, land degradation and hydrologic deterioration of the watersheds.

Locating, reclaiming and developing culturable wastelands, fallows other than current fallows and degraded soil conservation essay o meet increasing and competing demands for additional land stock for various sectors. Fewer people realize that their well-being also depends on the health of the soil. Soil supports the growth of most of our food and fibre, so its productivity is a major factor in the economies of Canada and other nations.

But soil also has a much broader, global role. Soil acts as a filter, cleaning air and water. It exchanges gases with soil conservation essay atmosphere and thus influences the global climate. Soil receives organic wastes and recycles their nutrients back to plants; it also holds and breaks down some toxic wastes.

Because soil plays such a key role in world health, economics and environmental stability, soil conservation essay, we must conserve it and use it in a sustainable manner. This practices aim at some objective soil conservation essay follows:? To divide a long slope of land into a series of shorter ones in order to reduce the velocity of run off water.

To retain the water in the land for long period so as to allow maximum water to be absorbed and held in the soil and less water flows down the slope of the land at non-erosive velocity.

To protect the soil against erosion by water. The important mechanical soil conservation measures are as follows: Contour bunding Contour bunding consists of building earthen embankment at intervals across the slope and along the contour line of the field. A series of such bund divide the area into strips and act as barrier to the flow of water.

As a result, soil conservation essay, the amount and velocity of run-off are reduced, soil conservation essay, resulting reducing he soil erosion. Contour bunding is made on land where the slope is not very steep and the soil is fairly permeable. Contour bunds are also called level terraces, absorbtion type terraces or ridge type teracces. Contour bunding works are carried out over wide areas in many parts of India, notably in Andhra Pradesh, Gujarat, soil conservation essay, Karnataka, Maharashtra and Tamil Nadu.

Terracing A terrace is an embankment of ridge of earth constructed across the slope to control run off and to minimize soil erosion. A terrace reduces the length of the hill side slope, thereby reducing sheet and rill erosion and prevents formation of gullies. There are different types of terraces as follows:? Bench terracing: It consists of transforming relatively steeps land into a soil conservation essay of level or nearly level strips or steeps running across the slope.

The soil materials that are excavated from the upper part of the terrace is soil conservation essay in filling the lower part and a small bund is also raised along the outer edge of the terrace to check the downward flow of rainwater and also soil erosion.

Channel terrace: It consists of making of wide but shallow channels across the slope of the land either exactly on contour line or with a slight grade 0. In this process, the excavated soil is placed along the lower soil conservation essay of the channel in the form of low ridge. Narrow based terrace: It consists of making a number of narrow based ridges or bunds at a distance of 1m to 2m across the slope of the land at suitable intervals in high rainfall areas. Broad based ridge terrace: It consists of making wide but low bunds on the contour lines by excavating soils from both sides of terrace, soil conservation essay.

This is practiced in areas where the rainfall is relatively low. Contour trenching: It consist of making a series of deep pit i.

The soil excavated from the trenches is deposited on the lower edge of the trenches where forest trees are planted. Land Development Land development consists of leveling and bunding to enable control of soil erosion and production of more remunerative crops.

Diversion Bund The uncontrolled discharge from the hillocks cause heavy soil erosion in uplands down below. So a diversion bund is put along the foot hill zone along the contour with proper safe disposal system to protect the land from soil erosion. Gully control The gullies are formed due to soil erosion in all types of lands.

A gully control measure consists of construction of series of check dams across the gully. These are supported by vegetative measures. The gullies threaten to engulf adjoining valuable lands and at times damage the roads and buildings. By gully control measures, the land is protected and in most cases reclaimed for cultivation.

Watershed Development The watershed is the geohydrological unit discharging the run-off to a particular point. The soil conservation measures on watershed basis have proved to be more effective.

Hence treatment measures on watershed basis from top to bottom down to the drainage line are taken up under watershed development programme with active participation of the people of the locality. It consists of basic activities like nursery, training, research etc and conservation and production system in arable and non-arable land, drainage line treatment and live stock management.

Agronomic soil conservation measures: Use of Vegetation Crops and vegetables which cover the ground surface well and have extensive root system reduce soil erosion. Plant canopy protect the soil from the adverse effect of rainfall.

The grasses and legumes produce dense sod which helps in reducing soil erosion. The vegetation provides organic matter to the soil. As a result, the fertility of soil increases and the physical condition of soil is improved. Following cropping systems help in controlling soil erosion. Crop rotation Crop rotation is planned sequence of cropping, soil conservation essay. Rotation of crop is an important method for checking erosion and maintaining productivity of soil.

A good rotation should include densely planted small grain crops, soil conservation essay, spreading legume crop soil conservation essay. Strip Cropping It consists of growing erosion permitting crop e.

Jowar, Bajra, Maize etc, soil conservation essay. Strip cropping soil conservation essay several good farming practices including crop rotation, contour cultivation, proper tillage, stubbles mulching, cover cropping etc. It is very effective and practical means for controlling soil erosion, specially for gently slopping soil conservation essay. It may be of different types as follows:? Contour strip Cropping: Contour strip cropping is the growing of erosion permitting and erosion resisting crops alternately in strips across the slope and on the contour line.

This practice is useful because it checks the fast flow of run-off water increases the infiltration of water in the soil and prevents soil erosion. Field Strip Cropping: Strips of crop are parallel to the general slope of the land. Wind Strip Cropping: Strips of crop are across the direction of wind regardless of contour. Buffer Strip Cropping: In this, the severally eroded portion of land soil conservation essay permanently kept under grass and contour strip cropping is practices in the rest of the area.

Cultivation of proper crops Cultivation of row crop in sloppy lands permits soil erosion. In this soil conservation essay, the crops particularly cereals, fodder crop etc. As a result, the movement of water gets obstacle and more water is absorbed in the soil, thus reducing soil erosion.

Mixed and intercropping Cowpea-Vigna catjang, with cotton — Gossipum Sp, maize — Zea mays with soyabean — Glycine max etc. The land should not be kept without crop There is very scope of soil erosion if there are no crops on the land. The soil erosion decreases in different way of cropped land. Afforestation Afforestation means growing of forests where there were no forests before owing to lack of soil conservation essay trees or due to adverse factors such as unstable soil, aridity or swampiness.

Along with afforestation, reforestation should be undertaken which means replanting of forests at places where they have been destroyed by uncontrolled forest fires, excessive felling and lopping. Afforestation is the best means to check the soil erosion. Lutz and Chandler cited the following points in support of vegetational check erosion as follows:? Infiltration of water is favoured due to high porosity of soil under vegetation, soil conservation essay. Percolation of soil conservation essay helps in preventing the soil moisture which accelerates further growth of the vegetation.

Surface accumulation of organic matter increases the water holding capacity of the underground soil, soil conservation essay. Root system of vegetation holds the soil mechanically and provides stability of the underground soil. It gives the protection against wind.

The forest vegetation shields the soil from direct effect of drought, snow and rain. Later on they decay to form humus soil conservation essay improves the physical condition of soil.

Natural mulching also helps in the infiltration of water and the reduction of evaporation. Organic manure: Organic manures improve the soil structure. The crumb and granular structure increases the infiltration and permeability in the soil and conserve the soil water. Consequently soil erosion decreases. Control of grazing Grazing increases the soil erosion. But the grazing cannot be completely stopped in all areas. So the restricted and rotational grazing may be helpful in checking soil erosion to some extent.

The area open to grazing for sometimes should be closed for the following year to facilitate soil conservation essay of forests and to maintain thick ground vegetation. Good tillage Soil conservation essay is the mechanical manipulation of soil by different kinds of implements. Tillage makes the soil loose and friable which helps in retention of water.

The special method of tillage practices should be followed for the conservation purposes. Tillage may consist of several types of soil manipulation such as ploughing, harrowing, cultivation etc. The quality of agricultural soils can also be maintained conserved or even soil conservation essay by using soil conservation practices.

Examples of these include adding organic material e. The type of farming activity that takes place on an area of land, be it pasture or cultivation of forage or fiber crops, cereals, oilseeds, berry fruits or vegetables, depends on the type of soil, the climate and whether crops are grown under natural rainfall or irrigation.
