      Soil pH levels don't directly show if nutrient are available - complex combination of soil types, soil moisture regimes and meteorological factors play a significant role. The important observation is that pH is the regulatory mechanism to plant nutrient uptake, and that the theoretical concentration of soil nutrients is meaningless until pH. Abstract. Resource-poor farm families in the seasonally-dry tropics suffer increasing insecurity of food and water supplies. Loss of soil porosity, caused by rain impact and/or damaging tillage, limits rates and amounts of water infiltration and percolation, provokes loss by runoff and thus diminishes possibilities for groundwater by: 2.

        Cont. Soil texture and structure play a vital role in determining the ability of the soil to produce high crops through their influence on some of these factors e.g. moisture holding capacity and drainage. Organic matter is another component which influences most of . ADVERTISEMENTS: Principles of soil conservation: The chief agents of soil erosion are water and wind. The actual art of soil conservation is based on certain basic principles which include: ADVERTISEMENTS: (i) Protection of soil from impact of rain drops (ii) To slow down the water from concentrating and moving down the slope in a narrow [ ].

      Conservation Farming. Like conservation tillage, this title covers many different farming techniques. It includes any farming practice which improves yield, or reliability, or decreases the inputs of labour or fertilizer, or anything else leading towards improved land husbandry, which we have defined as the foundation of good soil conservation. the World Overview of Conservation Approaches and Technologies (WOCAT) and reflects a long and intense participatory development process (WOCAT, in Mitiku et al., ). According to Mitiku et al. () the soil water conservation techniques are classified as management measures (such as land use change, areaFile Size: 1MB.

alternative conservation practice. Vegetative barriers are narrow strips ( feet wide) of stiff, erect densely growing plants, usually grasses, planted across the slope perpendicular to the dominant slope.

Over forty years ago, the USDA-Soil Conservation Service referenced the use of vegetative barriers in an agriculture handbook on conservation. Overgrazing and soil trampling result in impoverishment of species composition, reduction in vegetative cover and exposure to soil erosion (Thornes, ).

Nevertheless, degradation of grasslands. ADVERTISEMENTS: Some of the methods that must be adopted for conserving soil are as follows: 1.

Afforestation 2. Checking Overgrazing 3. Constructing Dams 4. Changing Agricultural Practices. Soil conservation includes all those measures which help in protecting the soil from erosion and exhaustion. Soil erosion has been continuing over, such a large part of India [ ]. Each new approach is described briefly, and then all are linked into a hierarchical network focused on promoting a more environmentally friendly and economically viable global agriculture.

It must be noted, however, that everything begins by first promoting an environmentally healthy soil. Modern concepts of soil conservation Cited by: Soil Conservation. Soil conservation is an important part of sustainable agriculture and food production, since it entails keeping soil from becoming a pollutant in the surface waters, and its ability to sieve and filter pollutants that would otherwise end up in drinking water.

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.

• Selection and design of structures depend on: • Climate and the need to retain or discharge the runoff.In such areas maximum conservation of water in the soil and reduction of soil erosion are the two main problems.

The improved dry farming practice developed as result of researches carried out in India is an integrated rational system of cultivation of purely rained and drought enduring crops in dry areas.
