      Factors which affect the rate of soil loss are rainfall, rate of run-off, soil types, slope, plant cover and presence or absence of conservation measures. The main objectives of soil and water conservation are to obtain the maximum sustained level of production from a given area of land by preventing soil degradation and environmental pollution. Soil is the most fundamental and basic resource. Although erroneously dubbed as “dirt” or perceived as something of insignificant value, humans can not survive without soil because it is the basis of all terrestrial life. Soil is a vital resource that provides food, feed, fuel, and by:

      Recently published articles from International Soil and Water Conservation Research. Soil and Water Conservation life on this planet, as the so il is an essential resource to suppor t plants for producing food, and to provide shelter to insects and animals. 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. Today these techniques of soil and water conservation are being prac- ticed in many countries with much benefit to great numbers of people.

      Conservation Service and other conservation agencies. Wisconsin is one of the first states in the nation to complete the entire initial soil survey and complete digital soil surveys for all counties. Soil surveys are now easily accessible on Web Soil Survey to help people make better land use decisions throughout the . Land degradation is a major concern in Ethiopia since it leads to declining agricultural productivity, poverty and food insecurity. Soil degradation is one of the crucial issues in mountainous areas of Ethiopia which needs efforts to reduce it. In the last two decades, various soil and water conservation interventions had been introduced in to different parts of by: 3.

For improved agricultural productivity, both the agronomic and structural measures of soil and conservation are necessary, especially on steeply sloping lands, where water conservation or drainage of excessive water are Size: KB.Soil Conservation and Water Conservation.

There are always strong links between measures for soil conservation and measures for water conservation, and this applies equally in semi-arid areas.

Many measures are directed primarily to one or the other, but most contain an element of both. Ebook MEASURES OF SOIL CONSERVATION In soil and water conservation programmes agronomic measures have to be considered in co-ordination with others for their effectiveness.

These measures are effective in low rainfall areas particularly in fairly erosion resistant soils having gentle slope .
