Gone with the Wind – A Top Soil Saga

Wind erosion has long been recognised as a major land degradation issue in Western Australia.

It involves the detachment, transportation and re-deposition of soil by wind.

Over the past few months, parts of our region have experienced particularly severe wind erosion events. Minor wind erosion occurs almost every year in WA agricultural regions, and substantial, serious wind erosion events occur in years like this, when strong winds, poor groundcover and loose soil coincide over large areas. 

Wind erosion is exacerbated by a number of factors, including our mediterranean climate, the prevalence of annual crops and pastures, strong prefrontal winds (which if you live anywhere in the Geraldton zone you will particularly understand this!) and extensive sandy-surfaced soils. These risk factors can be further intensified by poor groundcover, overgrazing, vehicle movements and land cultivation.

Autumn is usually the time of highest risk in the NAR.  A combination of dry groundcover, strong winds and land cultivation tend to expose and detach the soil leading to significant wind erosion.

Practical options for preventing and reducing wind erosion on your property include;
