Nematode-starving linseed ticks all the boxes.. The Jacksons started growing linseed three years ago after attending a GRDC Research Update at Goondiwindi, Queensland, where they learned the crop was resistant to Pratylenchus thornei and P. neglectus , which damage other plants' roots and reduce yield... Before growing linseed, the Jacksons ran a wheat/barley/canola rotation, but PreDicta B tests confirmed there were 17,000 P. thornei per kilogram in their black self-mulching clay soils after the cereal phase...

Water-repellent soils affect 30 per cent of Australia's cropping land, mostly in Western Australia... "We can look inside complex soils, such as vertisols, and can segment out the root system and can also see water in three dimensions in real soil samples, held undisturbed, or intact, from the field," Professor Young says... "People look at the weight or quantity of water available for plants, but it is really the surface tension between the soil and the water - the contact angle of that fine water film - that controls how water moves in soil, not the amount of water," Professor Young says...
