The project will link and integrate with another project on non-wetting soils 'Delivering agronomic strategies for water repellent soils in Western Australia' led by Dr Stephen Davies at DAFWA... The main focus of this project "Novel solutions for managing non-wetting soils", is to explore managements that promote water infiltration into non-wetting soils and increase crop production and profitability... At the beginning of the project a review will be done of current knowledge on strategies to manage non-wetting soils, including published research reports, grower knowledge and unpublished DAFWA reports...

The expression of water repellency under different tillage and stubble managements was evaluated to investigate anecdotal evidence that repellency disappears under zero-tillage and stubble retention... The results highlight the importance of evaluating water infiltration in the field to take into account not just the physical repellency of the soil, but to include all possible mechanisms of water entry... The results highlight the importance of evaluating water infiltration in the field and not just relying on laboratory measures of water repellency...

In this instalment of the Ground Cover matchmaker series highlighting advances made through grower-researcher collaboration, we look at how zero-till systems have been used to combat water repellence in sandy soils.. "Generally speaking, if you've got a sandy soil with a lot of organic matter in it, it will be quite highly repellent," says Dr Roper, who by then had been researching microbial degradation of waxes to improve water infiltration for a decade. ".. You would expect that the burnt-cultivated soil would have taken up much more water because it was less repellent, but when we measured water in the field the zero-till unburnt treatment had more water in the soil - and the least water was in the cultivated-burnt," Dr Roper says.
