Using deep ripping and cereal rye to fix blowouts after drought

Ben Ranford farms with his family at Cleve on the Eyre Peninsula. The area has an average annual rainfall of 330mm, with 250mm on average falling in the growing season. Their soils include some white non-wetting sands over clay but are mainly sandy loam. They generally work on a cereal and legume rotation, mainly lentils on the flats and vetch or field peas on the sandy rises, with canola also used in more promising seasons.

Ben finds that their sands are low in nitrogen, so legumes are essential in supporting soil carbon and biological activity. He uses a legume dominant mixed species green manure over about 10% of the farm each year.

Managing subsoil constraints

Throughout 2017 to 2020 the area suffered from challenging dry periods and damaging winds during critical growing season windows. The Ranford's have no livestock in their system, although they have still suffered some erosion damage on their sandy rises. To overcome these issues and protect their white sands, Ben has been deep ripping and delving while growing and returning crop residues to the soil, in addition to the use of other soil health improvement strategies.
