In 2011 we measured nitrogen volatilisation losses in 3 scenarios; (1) top-dressing wheat, (2) spring fallow broadcasting, and (3) autumn and spring fertiliser application to a grass pasture... We applied nitrogen fertilisers at locally relevant rates to 50-metre-diameter circular plots using either hand spreading (solid fertilisers) or a quad bike sprayer fitted with streaming-bar nozzles at 10 cm spacing (liquid fertilisers)... We used a grass pasture near to trial the method in autumn before the main trials began, and included a tropical grass pasture near Caroona in spring when measuring paddocks 5 & 6...

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."..
