There are various ways to reduce erosion, including reducing how much water runs off and the speed of that flow.
This fact sheet provides information on a trial conducted at Forthside Vegetable Research Station at Forth in north western Tasmania, which compared three treatments with a control (no treatment) to reduce the amount of water moving down a hillslope.
The treatments included an agro plough, single tyne and single tyne with straw drain (Ripper Mulcher).
