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 developed areas. A consequence of ...
The most effective known method for erosion prevention is to increase vegetative cover on the land, which helps prevent both wind and water erosion. [114] Terracing is an extremely effective means of erosion control, which has been practiced for thousands of years by people all over the world. [115]
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.
Silt fence installed on a construction site. Silt fences are often installed as perimeter controls. They are typically used in combination with sediment basins and sediment traps, as well as with erosion controls, which are designed to retain sediment in place where soil is being disturbed by construction processes (i.e., land grading and other earthworks).
Counteracting the effect of fire on the soil protection provided by the vegetation and surface cover: treatments such as seeding and mulching are aimed at reducing runoff and erosion by providing protection to the soil surface. They mimick above ground organic layers that protect the soil against the raindrop impact and absorb rain water ...
The Universal Soil Loss Equation (USLE) is a widely used mathematical model that describes soil erosion processes. [1]Erosion models play critical roles in soil and water resource conservation and nonpoint source pollution assessments, including: sediment load assessment and inventory, conservation planning and design for sediment control, and for the advancement of scientific understanding.
