A leading soil scientist is calling for an urgent rethink of how soil constraints are assessed with concern that an over-reliance on a commonly used soil test is resulting in costly and ineffective soil management strategies on-farm 38 per cent of the time. University of Southern Queensland’s (USQ) Professor John Bennett is leading a $3.3 million Grains Research and Development Corporation (GRDC) investment – the economics of ameliorating soil constraints in the northern region – investigating strategies to overcome two key constraints, dispersive and compacted soils.
