WA researchers have focused on the supply and loss of N from soils in WA dryland cropping systems... The University of WA (UWA) soil scientist Louise Barton presented a paper at the 2016 GRDC Grains Research Update, Perth, which has helped to quantify the supply and loss of N from soils in WA dryland cropping systems... "Accurate predictions of N fertiliser requirements are very important to growers and advisers," he said...

Capacitance soil water probes can provide useful information about soil water data when used with adequate professional support... Computer simulation models predict soil water information based on soil tests, soil characterisations and climate/rainfall data... Soil characterisation is about measuring the ability of the soil to hold water for use by a particular crop - or the size of the soil water 'bucket' - and takes into account potential constraints that affect the soil's ability to store water and plant's ability to extract it...

Tailoring inputs to match available soil moisture helps to optimise crop water use efficiency (WUE), yields, grain quality and profits... Recognising the wide range of soil moisture monitoring/measuring and climate tools now available to Western Australian growers, this year's joint GRDC and Department of Agriculture and Food, WA (DAFWA), Agribusiness Crop Updates included a focus session centred on the use of this technology... Mr Lemon says to Yield Prophet , N Broadacre, NUlogic, Fertiliser Optimiser, GreenSeeker/N rich strips and tissue testing are options to boost confidence in decisions...

P4/S9 and P2/S4 were the two most profitable sequences and, overall, the 'maximum profit - P4' philosophy had the highest mean gross margin... It is logical that those growers that have chosen to have no livestock will have no interest in trialling grazing crops... Overall, the data has indicated that for the biserrula inoculant all of the carrier's have difficulties in carrying enough live rhizobia numbers to adequately nodulate the legume hosts after 3-4 months of dry, hot soil...
