Erosion control is the process of reducing erosion by wind and water. During the last 40 years of the twentieth century, nearly one-third of the world’s arable land was lost to erosion, and topsoils continue to be lost at a nonsustainable rate, i.e., faster than it can be naturally restored.
Erosion Sediment Control

In most cases strip planting techniques should be used. The technique involves planting a strip of wet soil-tolerant, highly erosion-resistant vegetation in the critical area of the waterline, and conventional robust-rooted grasses and legumes above the critical zone. For added protection in selected locations, wet soil-tolerant bushes and trees can be planted near the waterline. For the protection of graded and planted areas until a strong stand of vegetation is established, an erosion control melting, or blanket can be utilized in addition to normal mulching practices. The local soil and water conservation district, the state forest service, and fish and wildlife agencies can help in selecting local types of vegetation for use in waterway stabilization.
Measures to Control Soil Erosion

Rough lands are usually located in hilly and mountainous terrain with shallow stony soils and steep slopes or in sand dunes. These are too marginal that they cannot be used for agriculture or forest land use and usually used for recreational purposes. In these lands, the overuse of paths and tracks results in a reduction in overall vegetative cover, compaction of soil and changes in soil moisture. Erosion control strategies in these areas include exclusion of people, use erosion-resistant plant species, improving drainage and soil strength. The plant species selected for re-vegetation of rough lands should ideally be local.
Long-term effects of Cement Kiln Dust (CKD) on erosion control of a soil slope

Erosion control uses one or more techniques based on the area’s geometry and geotechnical properties to prevent soil movement or make it less (Fay, Akin, and Shi 2012). Slope stabilization may be done by adding a surface cover, support structure, or changing the slope’s geometry and material to prevent failure or reduce erosion. Chemical compounds complying with environmental laws can stabilize soil (Faramarzi, Rasti, and Abtahi 2016; Ghazvinian and Razavi 2010). Cement kiln dust (CKD) is one of the chemical additives for soil stabilization. It is the waste of cement production releasing from the cement factory to the environment (Adaska and Taubert 2008). CKD is a fine, powdery, and highly alkaline material that contains sodium chlorides, potassium chlorides, sulphates, and volatile metal compounds. CKD collected from kiln exhaust in the term of cement production (Siddique 2006). CKD can be used in manufacturing, agriculture, civil engineering, and environmental sectors. The most crucial application of CKD includes blended cement and concrete, mine reclamation, agricultural amendment, water treatment, sewage treatment, asphalt mixtures, building ceramics, waste stabilization, and soil stabilizing (Siddique 2014).

Slash was the most abundant form of ground cover used on skid trails in the Piedmont and Coastal Plain regions, while grass was the most abundant cover used in the Mountains. Slash was also the most common form of cover on skid trails rated BMP+. Erosion control measures include ground cover in the form of slash, gravel, grass, mulch, and combinations thereof. Silt fence, hay bales, and check dams are also common in ditches. These trends are present in the data (Table 9). Several studies have compared a variety of soil cover BMPs for bladed and overland skid trails and concluded that applications of seed, slash, or mulch with seed can provide excellent erosion control if implemented appropriately (Sawyers et al. 2012; Wade et al. 2012; Wear et al. 2013). However, these studies concluded that slash is often the best option to retire a skid trail because slash decomposes slowly and provides cover for several seasons, while grass can be difficult to establish and may decline over time. Slash also restricts unwanted traffic and is usually the cheapest and easiest option for loggers as they complete operations.
