Wind erosion causes significant negative environmental impact and losses in productivity and profitably for grain producers. The resulting dust from wind erosion can contain about ten times more nitrogen, and twice as much phosphorus as the soil it is eroded from. This results in crucial soil and fertility being lost from the paddock.
The most effective way of controlling erosion is by maintaining groundcover and soil aggregation.
This farmtalk describes how to assess the erosion risk of a paddock by measuring groundcover using step pointing and percentage soil aggregation using soil sieving. It builds on information first discussed in farmtalk #1 and #22
