Wind erosion is a natural process that has assisted historically in shaping Australian landscapes. However, soil degradation by wind erosion has been augmented by inadequate or inappropriate land management practices.
Water erosion is the removal of soil from the earth’s surface by water. It occurs when raindrops impact the soil surface and displace soil particles and when water flowing over land surface mobilises soil particles.
Maintaining intact and anchored groundcover (e.g. living plants, litter, and mulch) on the soil surface is the major factor in reducing water erosion risk. Other soil conservation practices (e. g. contour banks, filter strips and controlled traffic) are also important but secondary to the maintenance of cover.
