  1. 1. 1.What is soil conservation? 2.What is soil erosion? 3.Two causes of soil erosion 4.Methods of soil erosion 5.Importance of soil conservation 6.Why should it be promoted?
  2. 2. Soil conservation is the act of keeping the soil in place and healthy. Soil and water conservation often go hand in hand, to help maintain the balance needed in the earth for people to live on and thrive. Where erosion is taking place or the soil is becoming contaminated with metals, acids or through overuse it becomes lost. This in turn means that an important source of food, carbon dioxide fighting plants shade and cover is lost with it. Soil conservation is the best way to make sure that we have the land we need to live on or, in my case, live in. If you see your soil eroding, protect it with grass or plants. If you see something that's making the soil sick, do everything you can to make the soil healthy again. If you live on a farm, make sure that the soil on your fields and pastures stays right where it is right now!
  3. 3. Soil is naturally removed by the action of water or wind: such 'background' (or 'geological') soil erosion has been occurring for some 450 million years, since the first land plants formed the first soil.Even before this, natural processes moved loose rock, or regolith, off the Earth's surface, just as has happened on the planet Mars. In general, background erosion removes soil at roughly the same rate as soil is formed. But 'accelerated' soil erosion — loss of soil at a much faster rate than it is formed — is a far more recent problem. It is always a result of mankind's unwise actions, such as overgrazing or unsuitable cultivation practices. These leave the land unprotected and vulnerable. Then, during times of erosive rainfall or windstorms, soil may be detached, transported, and (possibly travelling a long distance) deposited.

  5. 5. 1.COUNTOR PLOUGHING-Contour plowing (or contour ploughing) or contour farming is the farming practice of plowing across a slope following its elevation. 2.TERRACE FARMING-In agriculture, a terrace is designed to slow or prevent the rapid run-off of irrigation water. 3.STRIP FARMING-Strip farming is a method of farming used when a slope is too steep or too long, or when other types of farming may not prevent soil. 4.SHELTER BELTS- hedge or fence of trees designed to lessen the force of the wind and reduce erosion. 5.AFFORESTATION-The conversion (of land) into forest, especially for commercial use.
  7. 7. Soil conservation comprises of all the procedures and methods that involve protecting the soil from natural as well as manmade destructions. It is as important as any other form of conservation that attempts to safeguard the environment and improve the quality of life of all living beings.Soil conservation helps to prevent soil degradation due to erosion, agricultural soil pollution etc. Soil conservation is important to us because it forms the basis for habitats and plants, which act as a source of food to both humans and animals. Soil takes years to form and the greatest threat to soil is soil erosion. Soil conservation is a combination of all methods of management and land use that safeguard the soil against depletion or deterioration by natural or man-induced factors. It most often attempts to ensure that SOIL does not erode and wash into streams and lakes or blow away in the wind, but it also involves the protection of the soil from damage by machinery (eg, compaction) or by detrimental changes to its chemistry.
  8. 8. We need to conserve soil because it is a vital part of the ecosystem. Without good soil we cannot produce enough food and food is essential for life. Soil is essential for the growth of plants and trees, they help in purifying the air. Then herbivores feed on these plants. After these herbivores grow and flourish they will be consumed as food by the carnivores. When the carnivores die they 'll be decomposed into simpler substances, and the nutrients will be returned to the soil.So, basically everything is interdependent in our ecosystem. The concept of the conservation of soil takes into account the strategies for preventing the soil from getting eroded and preventing it from losing its fertility due to an adverse alteration in its chemical composition.We don't want the soil to lose its fertility because then we won't be able to use it to grow food and it also won't support healthy ecosystems built around healthy trees and plants. Lack of soil conservation is a big part of how deserts form and spread.
