[35] [36] There is growing evidence that tillage erosion is a major soil erosion process in agricultural lands, surpassing water and wind erosion in many fields all around the world, especially on sloping and hilly lands [37] [38] [39] A signature spatial pattern of soil erosion shown in many water erosion handbooks and pamphlets, the eroded ...
Splash erosion is generally seen as the first and least severe stage in the soil erosion process, which is followed by sheet erosion, then rill erosion and finally gully erosion (the most severe of the four). [10]: 60–61 [13] In splash erosion, the impact of a falling raindrop creates a small crater in the soil, [14] ejecting soil particles. [4]
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.
where R is the rainfall erosivity factor, K is the soil erodibility, [3] [4] L and S are topographic factors representing length and slope, and C and P are cropping management factors. Other factors such as the stone content (referred as stoniness), which acts as protection against soil erosion, are very significant in Mediterranean countries.
The erosion index (EI, also called the erodibility index) is created by dividing potential erosion (from all sources except gully erosion) by the T value, which is the rate of soil erosion above which long term productivity may be adversely affected.
As well as publishing in traditional aspects of soil biology, soil physics and soil chemistry across terrestrial ecosystems, the journal also publishes manuscripts dealing with wider interactions of soils with the environment. It was established in 1963 as the Australian Journal of Soil Research and obtained its current title in 2011.

Soil erosion is the result of natural physical forces, such as water and wind, gradually wearing away the topsoil in a field. [5] This process can be slow and inconspicuous or occur rapidly, leading to significant topsoil loss. [5] Apart from soil erosion, there are other severe soil degradation issues, including soil compaction, reduced ...
