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.

Health Details: Use cover crops and rotation to feed your soil. Develop a soil health management plan with the help of NRCS. Follow four basic soil health principles to improve soil health and sustainability: 1.

Though soil and water conservation SWC technologies have been adopted in Geshy subcatchment, their effects on soil quality were limitedly studied. The studied soils are characterized by low bulk density, slightly acidic with clay and clay loam texture. P at the bottom slope classes and terrace positions could be attributed to the erosion reduction and deposition effects of SWC measures. P deficient. Thus, integral use of both physical and biological SWC options and agronomic interventions would have paramount importance in improving soil quality for better agricultural production and productivity.

A variety of soil and water conservation measures are well known. These technologies can be differentiated either by their main purpose or by type. As many among them fulfil several functions simultaneously these are classified here by type see figure :. These measures are often used in combination, especially the many traditional soil and water conservation techniques. This is increasingly considered as reasonable.

SWCDs are also subject to other state statutes and rules, which govern the conduct and operation of public bodies. Each SWCD is governed by a five member board of supervisors elected by the citizens of the county. SWCDs: Conduct resource surveys and demonstration projects; Carry out soil and water conservation measures on any lands in the district with the consent of the landowner; Cooperate or enter into agreements with any governmental agency or individual landowner for the purpose of carrying on a program of erosion prevention and control; Purchase or accept property and income and provide equipment and supplies that will help to bring about conservation practices; Construct, install, improve, maintain, and operate such structures and works as may be necessary for proper performance of the district; Develop a comprehensive and annual plan for the conservation of soil and water resources. These plans are required for the district to receive state grant funds; Assume land by purchase, lease, or otherwise to improve, maintain, operate, and administer any soil and water conservation project undertaken by federal or state government; Sue or be sued; Require compensation or contributions for goods and services provided; Make application or enter into an agreement with a designated authority for federal assistance; Perform any other acts necessary to secure and use federal aid; Acquire land, easements, or rights-of-way needed in connection with works of improvement installed with federal assistance. Use necessary funds to provide membership in state and national associations that pertain to district operations and is authorized to participate and appropriate necessary funds to defray expenses of district representatives for meetings of such groups; Procure insurance directly or through the county in which the district is located; Publish any information relating to the activities of the district; Provide advice to or consult with county or municipal representatives; and Present an annual budget to the board of county commissioners.

Metrics details. Soil erosion is among the foremost causes of declining soil resources in Ethiopia, which in turn affect agricultural productivity. To limit this problem, for the last two decades in Gumara watershed, soil and water conservation measures have been practiced through free labor community mass-mobilization. However, their effect on soil fertility has not been evaluated. This study investigated the impact of implemented soil and water conservation measures on fertility improvement in the Gumara watershed. Both composite and core soil samples were taken from upstream, midstream, and downstream adjacent conserved and non-conserved cultivated and grazing plots. Selected soil fertility indicators were analyzed using standard laboratory procedures.

Effect of Soil and Water Conservation for Soil Fertility Improvement

Cation exchange capacity CEC 2. The population of the world is dependent on land resource for food and other necessities. Soil and water resources conservation and management is important for the welfare of the people Lal, This, according to Angima et al. These processes of degradation contribute to the worsening poverty and further marginalization of rural people in sub-Saharan Africa. If farmers' resource base cannot be secured and rendered more productive, the decline in rural standards of living will accelerate. Soil and water conservation must therefore be central to strategies of agricultural and rural development in sub-Saharan Africa.

Biological measures for soil and water conservation work by their protective impact on the vegetation cover. A dense vegetation cover. These effects entail a low soil erosion rate compared with an uncovered soil which shows in general a high soil erosion rate. Even cultivated crops in agricultural areas are a better protection against soil loss than uncovered soil relatively high soil erosion rate [ 27 ]. Other positive impacts have been observed, such as improved soil moisture condition or protection against erosion by wind.
