Sediment controls are usually employed together with erosion controls, which are designed to prevent or minimize erosion and thus reduce the need for sediment controls. Sediment controls are generally designed to be temporary measures, however, some can be used for storm water management purposes.
Erosion control is the practice of preventing or controlling wind or water erosion in agriculture, land development, coastal areas, river banks and construction. Effective erosion controls handle surface runoff and are important techniques in preventing water pollution , soil loss , wildlife habitat loss and human property loss.
Tillage erosion is the soil movement and erosion by tilling a given plot of land. [3] A similar practice is contour bunding where stones are placed around the contours of slopes. Contour plowing has been proven to reduce fertilizer loss, power, time consumption, and wear on machines, as well as to increase crop yields and reduce soil erosion.
Some residents along a rain-swollen Oklahoma river are evacuating after swift currents eroded the riverbank and undermined the soil beneath their homes. (May 22)
Contour buffer strips used to retain soil and reduce erosion. A buffer strip is an area of land maintained in permanent vegetation that helps to control air quality, soil quality, and water quality, along with other environmental problems, dealing primarily on land that is used in agriculture.
In Argentina the usage of no-till resulted in reduction of soil erosion losses by 80%, cost reductions by more than 50% and increased farm incomes. [16] In Brazil the usage of no-till resulted in reduction of soil erosion losses by 97%, higher farm productivity and income increase by 57% five years after the starting of no-till farming. [16]
Refuge Manager Amber Zimmerman said there have not been any impacts to public use facilities, the visitor center or the parallel forest.
Soil conservation is the prevention of loss of the topmost 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
