Millet can have a positive effect on following wheat yields, provided the millet crops are sown early in spring and terminated once 50 % cover is achieved... The results showed that if millet was sown early and removed early (40 days after sowing) there was a neutral or positive impact on wheat yield compared to a traditional fallow... The research shows that it is, differences in wheat yield when comparing the MF millet and CF traditional no-till fallows is significant and could be used to offset the costs of millet establishment...

Jason puts the boot into difficult soils.. Case in point: last year, in just four weeks, Jason, his father and uncle churned out 1000 seeding boots for growers in SA and Western Australia... Jason describes his early designs as "quite agricultural", but after on-farm testing he has refined the RootBoot, adding features from his own seeding wish list: extra tungsten for longer wear, drop-forged bolt-on knifepoint for extra strength, extra tile inserts on the point to eliminate side wear and three quick-change designs...

A new research paper presented at the Grains Research and Development Corporation (GRDC) Updates provides a comprehensive outline of the tools available to cost-effectively measure soil water leading into summer crop planting... "Devices include in-situ devices that have relatively small zones of measurement and rely on good soil/sensor contact to measure soil water are at a disadvantage in shrink/swell soils where soil movement and cracking are typical... "In comparison, the use of a portable EMI device to measure bulk electrical conductivity and calculate soil water has a number of advantages."..

In recent years, researchers have taken a closer look at the fundamentals of soil/tool interactions to shed light on the soil force system acting on disc seeder blades and how soil movement is induced by no-till furrow openers... Using UniSA's indoor seed-placement test rig, Dr Solhjou attached tillage tools to a frame that moves over bins of soil at desired depth and speed... When the furrow opener moved through the bin, these tracers were thrown with the soil and later located using a 3-D digitising frame to quantify soil movement, layer by layer...
