" 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)...

The nitrogen recovery in grain was calculated for all treatments (yield t/ha x protein % x 1.75)... The data from the trials was inconclusive in determining an optimal growth stage for application although the highest protein result was achieved from application during late head emergence to early milk at seven of the eleven sites... Although early application of additional nitrogen can cause canopy management issues, these results (in years with erratic or low spring rainfall) support the need to get nitrogen on early...
