" Goondiwindi GRDC Grains Research Update Day 1 - Tuesday 4 th March Time Topic Speaker (s) 10:00 AM James Clark (Chair Northern Welcome Panel GRDC) 10:10 AM General plenary (Supported by North West Local Land Services) 10:10 AM 10:40 AM.. Overall, both models are acceptable for modelling soil evaporation over a range of soils and seasons provided accurate soil physical properties and starting water states are known... Overall, populations increased five times compared to before planting the summer crops, but remained below 250/kg soil (Figure 4)...

By using the right amount of fertiliser at sowing and monitoring crop requirements throughout the season, growers can ensure nutrient-rich water doesn't escape into nearby rivers and simultaneously improve crop profitability," Dr Nash says... Better defining the relationships between inorganic soil nitrogen, fertiliser application rates and yield for different seasonal conditions is important. ".. Researchers found: Dr Nash says that minimising nitrogen applications at sowing also reduces non-redeemable costs and defers some expenditure decisions until later in the season when other factors affecting crop performance, such as moisture limitations or waterlogging, are evident.

Faba bean foray into the north takes hold.. With his wife Janette and son Lance, Murray was one of the first growers to sow faba beans on the Darling Downs - a region that supports about a third of all northern grain growers... In delivering faba beans to Todd Jorgensen's AssociatedGRAIN in Dalby, Murray says "cashflow" from the crop averaged $454 a tonne in 2014...

In delivering faba beans to Todd Jorgensen's AssociatedGRAIN in Dalby, Murray says "cashflow" from the crop averaged $454 a tonne in 2014... Murray says that so far, the operational efficiency gains that stem from harvesting earlier have outweighed the risk of wet conditions downgrading the quality of the beans, which are susceptible to damage in windrows...

Understanding and applying the principles of canopy management, allows decisions on the most profitable use of inputs and the most appropriate target yield to be made... Applying nitrogen (N) or fungicide at stem elongation increases the opportunity to match input costs to the potential yield for that season... The visual difference can be quantified by using crop sensors that measure the light reflectance from the crop canopy...

Dr Imma Farre has developed a simple framework to help growers and advisers make better fertiliser decisions... A simple framework has been developed to help growers and advisers make better fertiliser decisions based on maximising profits, rather than crop yields... Her analyses of nitrogen and wheat prices during the past decade indicate gross margins are optimised when growers and advisers can predict the yield response to a wide range of nutrient rates, rather than those typically used for the expected yield...
