The concept of soil conservation cannot be materialized without conserving and efficient use of water resources. - The benefits of many soil conservation methods, depending on the material used, may also include better control of weeds, provision of additional nutrients to the soil, soil temperature control and protection of soil surface from the impacts of heavy rain and wind. Soil conservation is the prevention of loss of the top most layer of the soil from erosion or prevention of reduced fertility caused by over usage, acidification, salinization or other chemical soil contamination.. Slash-and-burn and other unsustainable methods of subsistence farming are practiced in some lesser developed areas. Introduction to Soil Erosion: Soil Erosion is the main problem in Agriculture. Water Erosion 4.1.1. World Association of Soil and Water Conservation, Bristol, England,UK Keywords: soil conservation, soil erosion, wind erosion, water erosion, erosion control Contents 1. Modern Soil Conservation 4. Introduction to Soil Erosion: Soil Erosion is the main problem in Agriculture. SOM can be considered as the most important soil fertility and quality factor influencing other soil properties as infiltration, water holding capacity or soil structure. Three methods of soil conservation include the prevention of soil erosion, reducing tillage and rotational grazing to prevent overgrazing.

Soil conservation is the practice of protecting the soil against erosion or deterioration. Tonnes of soil are gone from the fields every year.
Tonnes of soil are gone from the fields every year. The surface layer of the soil can be destroyed by the actions of water or wind, so it is customary to distinguish water and wind erosion of the soil. Soil and water conservation measures are predominantly applied for the following purposes: to control runoff and thus prevent loss of soil by soil erosion, to reduce soil compaction; to maintain or to improve soil fertility; to conserve or drain water; to harvest (excess) water (Tidemann 1996). This involves, in many instances, changing the uses to which land is put. The management and conservation of our water resources depends heavily on the conservation of soil integrity. Today, we are discussing Soil Erosion Causes, Types, Soil Conservation Methods. By admin on February 5, 2011 in water conservation. Soil erosion, use of chemical pesticides and herbicides, unsustainable agricultural practices, excessive farming, water pollution and land pollution are some of the aspects upsetting the natural functions of the soil. Types of erosion. It is therefore pre-requisite that soil conservation practices should be adopted. Soil conservation and water conservation are achieved simultaneously and go hand-in-hand. Wind erosion occurs mainly in steppe areas with large open spaces. Thus, when a plane table is properly oriented, the lines on the board are parallel to the lined on ground which they represent. Today these techniques of soil and water conservation are being prac- ticed in many countries with much benefit to great numbers of people. The primary purpose of soil and water conservation is to prevent soil erosion and heal its scars where it has not advanced too far to respond to curative methods. These traditional water conservation methods had been developed in India looking to the nature of rainfall in different regions, but the increasing population necessitated extension of agriculture, leading to deterio­ration of these traditional sources. This not only reduces crop cultivation, but the soil also acts as a pollutant to rivers, lakes, and other water systems. Soil conservation stores more of the runoff from excess rainfall in the reservoir of the soil for subsequent crop use; and this much water is kept out of streams, thereby contributing to flood reduction. Department of Soil & Water Conservation Engineering The process by which the position occupied by the board at various survey stations are kept parallel is known as the orientation. Purpose of Soil and Water Conservation Measures. Soil fertility is kingpin in soil and water conservation which helps to reduce runoff and consequently erosion is automatically minimised.
