Erosion can also affect air quality. In extremely arid conditions, topsoil becomes so dry that a strong wind can pick up the top layer and blow it away. This can cause dust storms, such as those that plagued the central United States during the droughts of the 1930s. According to the Ea...
Soil ingestion by humans: a review of history, data, and etiology with application to risk assessment of radioactively contaminated soil. Health Phys. 74, 647-672.Simon, S L, 1998, Soil ingestion by humans: A review of history, data, and etiol...
of the past 12,300 years soil erosion and development were impacted differently by natural climate variability, as recorded by sediments deposited in Lake Dojran (Macedonia/Greece): short-lived ( < 1,000 years) climatic shifts had no effect on soil development but impacted soil erosion. Thi...
Finally, healthy soils promote good clean air quality, are less prone to wind and water erosion, and provide clean and safe water through filtration, decontamination by microbes and removal of pollutants. Soil biodiversity is highly recognized now as an important feature of healthy soil and ...
limit oxygen diffusion and reduce runoff and erosion of OC (Bach and Hofmockel, 2016; Jastrow, 1996; Six et al., 2004; Tisdall and Oades, 1982). Changes in the amount and structural stability of aggregates would therefore affectSOC storageand composition. In general, the increase in aggrega...
Improvement of the P-factor. The P-factor reflects the efficacy of support practices that humans made to control soil erosion with a range of 0 (no soil water erosion) to 1 (no support practices)21,22. However, the P-factor is difficult to quantify in large-scale modelling of soil ...

Soil conservation(保护) efforts protect soil from wind and water that can blow or wash it away. Good soil produces food crops for both humans and animals. One important form of soil conservation is the use of windbreaks. Windbreaks stop the wind from blowing soil away. They also keep the ...
Pedomorphic form (Dan and Yaalon, 1968): a unit of soil characterized by a definite horizon sequence which reflects its degree of maturity and history of erosion or sedimentation; conceived as being a member of a catenary sequence of pedomorphic forms, related by the influences of topography on...
Soil stability is enhanced by these soil crusts through the formation of exudates of polysaccharides that bind soil particles into aggregates. They also protect the soil from raindrop erosion (the dislodging of soil particles by individual raindrops, also known as splash erosion) by absorbing the ...
