“…Michels et al ( 1995a) reported that a mass transport rate up to 8.3 g m" ' s" ' did not damage the pearl millet plant, whereas a rate >25.0 g m~' s~' did cause damage (the effect of mass transport rate between 8.3 and 25.0 g m" ' s" ' was not examined). In 2005In ,2006In , and 2007, there were zero, five, and two storms in which the mass transport rates exceeded 25.0 g m~ s~ (Fig. 7).…”

In the previous field-scale wind erosion studies in the Sahel, mass flux profiles, mass transport rates, and soil mass balance in the cultivated field and fallow land were estimated without measuring the mass flux at 0-to 0.05-m height where most soil particles are expected to move. We first addressed these deficiencies using a 3-yr field study in which mass flux at 0 to 0.05 m was measured directly with the Aeolian Materials Sampler (AMS) and then evaluated field mass transport rate, field soil loss, and fallow soil gain. We found that field mass transport rate, field soil loss, and fallow soil gain for each erosion event could not be estimated accurately without measuring the mass flux at 0 to 0.05 m. The field measurements of whole mass flux profiles revealed that (1) field mass transport rate at 0 to 1.0 m sometimes exceeded 40.0 g m~ ' s~ ', leaving pearl millet plants severely damaged, (2) field soil loss was 58 to 80 Mg ha"' (4-5 mm of topsoil) that was about 10% greater than those estimated without measuring the mass flux at 0 to 0.05 m using the AMS, and (3) fallow soil gain was 77 to 93% of the field soil losses. Results 2 and 3 implied that large amounts ofsoil were eroded from the field but that most sediment settled within about 5 m Into the fallow. Tliis finding provides useful information for the development of a countermeasure against wind erosion.

“…Monsoons and high wind conditions over open desert landsprovide optimum conditions for the wind erosion processesin the area, leading to sandy wind erosion sediments. Visser et al (2005) have also reported that wind erosion is responsible for loss of nutrients and fine particles in the Sahel region in West Africa. It is also estimated that the annual loss of soil carbon to erosion in northern China dust storms is between 53 and 1044 kg ha (Wang et al, 2006).…”

Wind erosion effecting on soil carbon losses, should be considered from the standpoints of sustaining farmland productivity and producing accurate national carbon accounts.The worldwide spread of arid and semiarid areas with extensive damage to these areas gives them potential for carbon sequestration. Considering that a large portion of soil carbon is concentrated in 0 to 20 cm soil depth, carbon sequestration increases soil fertility, prevents erosion and improves the hydrological system. This paper introduces a case study in Dejgah catchment, Farashband County, Shiraz Province, Iran, which used to be a typical area with wind erosion and desertification in south western Iran. A field experiment was conducted in this region to investigate changes in soil carbon in relation to wind erosion. Samples were taken randomly from areas of up to 0.25 ha from each of the different wind erosion categories in June 2011. In each site 20 samples from surface layer (0 to 10 cm) and 20 samples from subsurface layer (10 to 20 cm) were collected, then samples from each layer were combined. Finally, two composite sample from each site and 24 composite soil samples were collected from surface layer (0 to 10 cm) and subsurface layer (10 to 20 cm) in 4 different wind erosion categories (light, moderate, high and severe). In the laboratory, each soil sample was thoroughly sieved to 2 mm to remove roots and incorporated litter and air-dried to determine soil physicochemical properties including pH, electrical conductivity, soil texture, bulk density, total nitrogen, and organic carbon content. Analysis results showed some soil properties largely influenced by the severity of wind erosion. In addition the results showed the impact of wind erosion on loss of carbon and nitrogen so that the organic C and N contents decreased significantly with wind erosion development. In addition changes in organic C content had a significant positive correlation with the soil fine particle content (clay) (Pb 0.01) and a significant negative correlation with sand content (Pb 0.01).

“…Dust emission is a selective process whereby nutrient-and carbon-rich, fine material predominantly get lost, while coarser sand particles remain and accumulate at the soil surface or near the source (Visser et al, 2005;Harper et al, 2010). Wind erosion from arable fields is highly variable in time and space, and often effects single bare fields with great intensity (Hoffmann et al, 2011).…”
