Annually, there is an estimated $7 billion in damage caused by clay shrink-swell soils. [11] All this damage is caused by the force exerted by expanding soil, or ground heave. Expansive soils are the most problematic in regions with very defined wet and dry periods, as opposed to areas that maintain a certain level of moisture throughout the ...
The Great Lakes Basin Soil Erosion and Sediment Control Program is an American federal and multi-state environmental and agricultural program to water quality, land use, and agricultural productivity pertaining to the Great Lakes Basin. It was authorized by the Farm Security and Rural Investment Act of 2002 (P.L. 107-171, Sec. 2502).
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.
Sulfate attack typically happens to ground floor slabs in contact with soils containing a source of sulfates. [2] Sulfates dissolved by ground moisture migrate into the concrete of the slab where they react with different mineral phases of the hardened cement paste. The attack arises from soils containing SO 2−
Expansive clays have an expanding crystal lattice in a 2:1 ratio; however, there are 2:1 non-expansive clays. [2] Mitigation of the effects of expansive clay on structures built in areas with expansive clays is a major challenge in geotechnical engineering. Some areas mitigate foundation cracking by watering around the foundation with a soaker ...
Controlled traffic farming (CTF) is a management tool which is used to reduce the damage to soils caused by heavy or repeated agricultural machinery passes on the land. This damage and its negative consequences have been well documented and include increased fuel use , poor seedbeds , [ 1 ] reduced crop yields and poor soil function in terms of ...
A sediment control is a practice or device designed to keep eroded soil on a construction site, so that it does not wash off and cause water pollution to a nearby stream, river, lake, or sea. Sediment controls are usually employed together with erosion controls , which are designed to prevent or minimize erosion and thus reduce the need for ...
Organic farming in particular emphasizes optimal soil management, because it uses soil health as the exclusive or nearly exclusive source of its fertilization and pest control. Soil management is an important tool for addressing climate change by increasing soil carbon and as well as addressing other major environmental issues associated with ...
