Soil conservation measures should aim at preventing or at least minimising the soils loss. In order to do this proper land utilisation coupled with agricultural practices should be adopted.
Effects of conservation tillage on soil properties vary, and these variations depend on the particular system chosen. No-till (NT) systems, which maintain high surface soil coverage, have resulted in significant change in soil properties, especially in the upper few centimeters (Anikwe & Ubochi, 2007).
CDM Methodology Booklet: The function of methodologies is easy to grasp, but the methodologies themselves can be quite complex.They are necessarily diverse in their composition and application in order to accommodate the wide range of activities and areas covered by the CDM.

Conservation scientists and foresters manage the overall land quality of forests, parks, rangelands, and other natural resources.
Tillage is the agricultural preparation of soil by mechanical agitation of various types, such as digging, stirring, and overturning. Examples of human-powered tilling methods using hand tools include shovelling, picking, mattock work, hoeing, and raking.
Soil conservation is the preventing of soil loss from erosion or reduced fertility caused by over usage, acidification, salinization or other chemical soil contamination. ...
4. SOIL CONSERVATION 4.1 PRINCIPLES 4.1.1 The Extent of Erosion. The lower rainfall in semi-arid areas compared with that in humid climates does not mean a corresponding low level of soil erosion by water.
How to Increase Nitrogen in Soil. When you cultivate a garden, you want to make sure your plants grow in the healthiest conditions possible. There's no nutrient more important to the health of your garden than nitrogen!
In this lesson, students explore and verify that soil erosion is affected by the makeup of the soil using plant roots, rocks, and the slope of the land as experimental factors.
Web Soil Survey (WSS) provides soil data and information produced by the National Cooperative Soil Survey. It is operated by the USDA Natural Resources Conservation Service (NRCS) and provides access to the largest natural resource information system in the world.
