Keep Your Soils Undercover

As a farmer you cannot control the wind but you can manage soil condition and ground cover by controlling grazing rates and cultivation strategies. Areas subject to wind speeds that exceed 30km/hr at 10m above the soil surface have a higher erosion risk. Light sandy soils have higher risk of erosion than heavier soils as soil particles detach more easily due to less binding from the clay.

One of the best ways to reduce the risk of wind erosion during summer is to head out into the paddock and do a ground cover assessment to estimate how many grazing days the paddock can provide a suitable stocking rate. The risk of wind erosion this year is higher than usual as the dry season has reduced the ground cover level from lower yielding crops and the soil is drier, therefore more susceptible to erosion.
