Building The Soil Carbon Sponge At Murray Wells Farm, Tambellup, Western Australia, Wendy Bradshaw
Building The Soil Carbon Sponge At Murray Wells Farm, Tambellup, Western Australia, Wendy Bradshaw
Natural resources published reports
Peter and Wendy Bradshaw farmed at Murray Wells Farm about 25 km west of Tambellup for around 46 years until they sold and retired in 2022. They produced barley, oats, merino and prime lambs on an annual rainfall of 450 mm over 1,000 arable hectares. The farm was on a moderately undulating landscape with a mix of soils including sandy duplex, well-drained sand over gravel over clay, shallow sandy or loamy gravel over cemented laterite and red to brown loamy soils.Their farming philosophy was to view agriculture as an ecological enterprise that included them as part of the ecosystem, and …

Building The Soil And The Community At Hollands Track Farm, Newdegate, Western Australia, Jamie Bowyer, Nick Kelly
Natural resources published reports
The Kelly family have been farming at Hollands Track Farm, about 18 km south-west of Newdegate, since 1965. They currently produce grains, beef, eggs and sheep. Long-term annual average rainfall is 350 mm. The Kellys were early adopters – in the 1990s – of the no-till farming system, which is now widely used in Western Australia. Around 2002 they sold the last of their sheep and moved to a continuous cropping program with increased fertiliser and chemical use. They were very good at this system, and it served them well. They really enjoy the challenge of growing good crops. Over …

Dryland salinity is a pervasive form of land degradation that has resulted from the clearing of about 17 M ha of native vegetation and the introduction of predominately cereal and pasture-based farming systems in the South-West of Western Australia. The change in water balance caused by clearing deep rooted endemic woodlands increased recharge and resulted in rising groundwater levels. After a lag period, the regolith began filling and groundwater approached the soil surface, evaporating and depositing stored salts in the rootzone of salt sensitive crops. Groundwater levels also rise and affect areas of remnant native vegetation, streams, wet-lands and rural …
Rehydrating The Landscape At Yanget, Geraldton, Western Australia, Jamie Bowyer, Rod O'Bree
Rehydrating The Landscape At Yanget, Geraldton, Western Australia, Jamie Bowyer, Rod O'Bree
Natural resources published reports
Rod and Bridie O’Bree’s farm is 25 km east of Geraldton in the Northern Agricultural Region of Western Australia. The long-term rainfall average is 486 mm although that has dropped to 354 mm over the last 30 years. They run a 150 head beef cattle herd, fatten 500-700 lambs annually and have a 40-60 head horse stud on the farm. They purchased the farm early in 2008 after one of the worst droughts in the area. There was little to no vegetation, brown or green, across the farm and all of the water from a 25 mm rain event ran …
