year it’s a particular challenge as we contend with growth stages ahead of time. 970 and long season canola residuals at lock up are important. There is a strong correlation between plant biomass and yield when at flowering. Crops that are locked up mid July can have lower residuals (ie < 12-1500 kg / Ha), however these residuals in early to mid August are not favourable. Farmers should monitor green bud development for a better handle on lock up timing.
Nitrogen – Undertake deep N soil testing to validate top dressing requirements. Alternatively consider that yield potential is basically satisfied at stem elongation in cereals, applied nitrogen from this growth stage will more so target grain protein. Tiller numbers this year are staggering, therefore there will be obvious short comings in protein if not addressed in wheat. Consider paddocks (NOW) that will enter farming rotations or clean up phase in late 2020 or 2021.
Tips for the coming weeks NSW Tablelands clients, if not already, should be preparing for spring planting. Organising soil tests and understanding lime and fertiliser requirements should be complete at this stage. Various pasture and fodder crop seeds may be in short supply, early commitment and procurement is recommended. Understand crop phenology and the effects of over grazing dual purpose crops is highly valuable. But this
