Farmers are being reminded to keep an eye on their soils as the late summer dry continues through the region.

Graziers need to consider de-stocking vulnerable areas of their farm to reduce the chance of dust storms which are capable of stripping the soil of valuable organic material.

AgVic land management extension officer Clem Sturmfels said holding stock in a paddock to make use of the last of a water source could be ‘all it takes’ to expose the soil to wind erosion.

“The most vulnerable areas are those with lightly textured soils, little groundcover and shelter belts, and topography that exposes them to high wind speeds,” Mr Sturmfels said.

“Wind erosion can start anywhere the soil has been disturbed, such as in gateways, along tracks and around water troughs.

“Once the process of wind erosion starts it can be nearly impossible to stop.”

Lighter textured soils are those containing a high proportion of sand with little or no clay.

Bare soil is also susceptible to oxidation and microbial activity that can release stored carbon and nitrogen.

Mr Sturmfels said wind erosion could be prevented by maintaining as much ground cover as possible and avoiding disturbing the soil.

“Aim for 80 per cent cover in pasture paddocks and 60 per cent cover in crop stubbles.

“Ground cover also helps moderate temperature extremes in soil and retains moisture.”

Good ground cover also allows for soil recovery following the autumn break.
