A decade of liming and recent mouldboard ploughing efforts on their Badgingarra property has helped to double cereal crop yields for Jeff and Wendy Fordham... The soil renovation techniques have been used in an attempt to address aluminium toxicity issues on yellow sandplain country and overcome problems of non-wetting sands... Technology to reduce spray drift GCTV: Drift Reducing Technology..

Experience builds strategies for water-repellent soil.. Recent research indicates that some formulations only work on certain soil types, such as the forest loamy gravels or on firmer soils with reasonable clay content, and are less effective on repellent sands... The results indicate a 55 per cent chance of achieving a yield increase of 400kg/ha or more in year one...

Developing and assessing agronomic strategies for water repellent soils davies table 1.. It should be noted that the yield responses measured with paired cuts on water repellent areas were quite large compared to the average grain yield advantage for the winged point-paired row system across the whole paddock (200 kg/ha)... Recent research has shown that a topsoil clay content of 3% is sufficient to overcome topsoil water repellence where the organic carbon content is 1% but higher clay contents of 5-7% are required where the organic carbon content is higher at 1.5% (DAFWA Bulletin 4773, 2009)...

It should be noted that the yield responses measured with paired cuts on water repellent areas were quite large compared to the average grain yield advantage for the winged point-paired row system across the whole paddock (200 kg/ha)... Recent research indicates that some of these formulations only work on quite specific soil types such as the forest loamy gravels or on firmer soils with reasonable clay content and are less effective on the repellent sands... Soil water content contradicted the findings on water repellence and indicated that water infiltration was best under zero-tillage and stubble retention and poorest under stubble removal and cultivation (Figure 1B), and this impacted on crop performance...
