in future, soil erosion will be a great challenge for biosphere. if the soils today are notprotected carefully hunger crises all over the world will be widespread. the present article endeavorsto survey soil erosion process and approaches to prevent it. furthermore the article tries to review therelation between soil character and soil production capability shedding light on the effect of erosi...

soil conservation is one of the most important regulative functions of natural ecosystems. this function is of high importance in taleghan watershed due to high erosion quantity and sediment accumulation in taleghan dam reservoir. soil loss reduction, sedimentation control and fertility conservation were considered as different aspects of soil conservation. effect of land use and vegetation cov...

soil, a 3-dimensional component of the landscape, or simply a natural body in a soilscape with a given geopedological setting, was modeled by jenny as s = f (climate, organism, relief, parent material, time). to map such a complex body, the concept ‗pedon’ –the smallest volume that can be recognized as a soil had to be defined. classically, soil is known to function as provider, controller, reg...

Soil erosion is one of the important and worldwide environmental and economic issues. High amount of sediments accumulations behind the different structures such as dams requires several attempts to minimize their potential risks. Therefore, some quantified data will be needed in order to recognize those critical areas which requires urgent conservation. Since conventional procedures are time c...

Water erosion leads to the loss of soil, nutrients, organic matter, disruption soil structure, reduction moisture capacity, biodiversity, and is most significant degradation process when growing agricultural crops on sloping terrain. Soil microorganisms are basis functioning ecosystems, circulation substances, soil-forming processes formation structure. Microbiological indicators, such as numbe...

Conservation tillage (CT) systems have a number of potential benefits including lower crop production costs and the ability to reduce soil erosion that have made them common in several regions of the world. Although CT systems have been researched and successfully implemented on some farms in California's San Joaquin Valley (SJV), overall adoption is low and the reasons for the region's compara...

Agricultural productivity levels depend on the adoption of (improved) agricultural technologies, among other aspects. However, the use of improved technologies in Mozambique is still very limited. Data from the National Agricultural Survey of 2012, known as Inquérito Agrícola Integrado, show that less than 3% of smallholder farmers used inorganic fertilizers, 6% used pesticides, 9% used improve...
