How paddock science solved a soils puzzle

Plain text source: 
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.
