Soil Erosion
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.
Wind and water erosion fact sheet
Visit the Agriculture & Food WA government website for a detailed insight into controlling wind erosion, specifically during summer, and harvest.
As such a topical issue, affecting so many land managers across the south coast, information is constantly changing as we learn more and more about controlling erosion. Have a read of this Farm Weekly article, discussing the importance of timing in mitigating wind erosion.
