Soil conservation. In addition, agronomists develop methods to preserve the soil and to decrease the effects of erosion by wind and water. For example, a technique called contour plowing may be used to prevent soil erosion and conserve rainfall. Researchers in agronomy also seek ways to use the soil more effectively in solving other problems. annual soil loss simulated using the Universal Soil Loss Equation (USLE) (Wischmeier and Smith, 1965, Wischmeier and Smith, 1978). The USLE is a model widely used in the estimation of soil erosion and supporting soil conservation measures (Song et al., 2005), and is the standard technique for soil conservation workers (Morgan, 2005).

Certain conservation measures can reduce soil erosion. Soil / land management practices such as tillage and cropping practices, directly affect the overall soil erosion problem and solutions on a farm. When crop rotations or changing tillage practices are not enough to control erosion on a field, a combination of measures might be necessary The erosion preventative measures mainly comprise the agronomic soil and water conservation practices that improve land productivity without construction of structures (see Training Manual 4 in these series). The erosion control measures involve the construction of various structures for the

soil conservation practices adopted in the study area were developed to minimize soil erosion, to conserve soil and water and to protect the soil long-term productivity. These include agronomic measures such as fallow pastures, cover crops, crop rotation, ridge planting, stubble retention on the soil surface and mulching, incorporation of stubble supplementary use of soil amendments and conservation technologies, poses a serious threat to sustainable land use (Bekele & Holden, 1999).

However, SWC measures that are both protective and sufficiently productive have not yet been implemented in the conserved sub‐watershed. Therefore, it is important that SWC structures be supplemented with other biological and agronomic measures in conjunction with soil fertility amendments appropriate to site‐specific conditions. ADVERTISEMENTS: The main aims of soil conservation are as follows: (1) To protect the soil from erosion. (2) To maintain the productive capacity of the soil. ADVERTISEMENTS: Soil erosion is a natural phenomenon by which soil is removed from rocks. Accelerated erosion due to misuse of resources of land, water and soil is today one […]

Soil conservation is the prevention of soil loss 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. Thus, biological measures are an effective method of soil and water conservation, especially since they are low in cost . Additionally, these can be used with structural and agronomic measures. Several types of biological soil and water conservation measures exist (see figure). Afforestation is …

Evidence-based Soil Conservation Measures that Improve Soil Physical and Chemical Properties and Barley Yield S oil degradation can be described as a reduction of resource potential by a combination of processes, such as soil erosion by water and wind, acting on the land and bringing about deterioration of the physical, chemical, and Soil conservation. In addition, agronomists develop methods to preserve the soil and to decrease the effects of erosion by wind and water. For example, a technique called contour plowing may be used to prevent soil erosion and conserve rainfall. Researchers in agronomy also seek ways to use the soil more effectively in solving other problems.

Agronomic conservation measures function by reducing the impact of raindrops through interception and thus reducing soil erosion. They also increase infiltration rates and thereby reduce surface runoff. Widely used agronomic measures for water erosion control are listed below. 4.2.1 Contour Cropping present and give an overview of fundamental and applied aspects of soil conservation. The Congress is open to educators, NGO’s and policy-makers in order to be informed by experts in the field of application of a series of innovative measures for soil conservation.
