The Hillslope Erosion Project aims to build awareness of hillslope erosion and to increase adoption of best practise mitigation techniques to minimise future soil erosion.
The Hillslope Erosion Project will focus on areas in Northern Tasmania with intensive cropping enterprises and high susceptibility to hillslope erosion such as Deloraine and Scottsdale. Trial sites will be established over the duration of the project period to investigate the cost-benefit ratio of different hillslope erosion mitigation techniques.
“Any cover is better than no cover at all. You need to think of these techniques as a form of insurance, because it’s worth your time and the cost involved to protect your most valuable asset.”
Dr Bill Cotching
Tasmania's most productive vegetable-growing areas have long suffered from significant hillslope erosion due to high rainfall, sloping paddocks and crops that require bare seed beds.
Satellite images show red/brown flumes of soil being washed out into sea from these cropping areas following intense rainfall. This is a loss of Tasmania's best soil and nutrients, with economic and environmental ramifications.
Soil erosion mitigation techniques will be communicated and promoted through:
Return to the Land Program.
Raising awareness of the limitations in productivity caused by soil acidification in pastures.
Improving carbon flow into the soil in cropping systems and pasture.
Providing important core agricultural services within the NRM North region.
