The capacity of the plant to take up potassium is not directly related to potassium in solution... Spraying is best done when there is some wind, and when the operator can be sure that wind direction has stabilised... Driftability of amine formulations The 2,4- D products Surpass and Amicide 625 which were used in the trial are considered to be nonvolatile any drift that is associated with these products will be droplet drift not vapour drift...

In the short term (at least the next 8 years), these crops will in essence provide new uses for old herbicides and old herbicide groups... In summary, the research also indicates that the public is least likely to approve of GMOs that: Benefit a company over the public; Involve gene transfer from species that are not closely related; Are not undertaken for a societal benefit; Are perceived as being possibly harmful to people or the environment; or Is a food over a non-food application... At the outset of the project, a draft strategy was proposed, and it was this strategy that the project team and participant growers/consultants worked towards implementing and evaluating...

Paddock records help: establish realistic target grain yield/protein levels prior to planting modify target yield/protein levels based on previous crop performance, planting soil moisture, planting time, fallow conditions, expected in-crop seasonal conditions and grain quality requirements determine appropriate fertiliser type, rate and application method compare expected with actual performance per paddock and modify fertiliser strategies to optimise future yield/protein levels... Valuable information obtainable from a soil test includes current nutrient status, acidity or alkalinity (pH), soil salinity (Electrical Conductivity (EC)) and sodicity (Exchangeable Sodium Percentage (E)), which can affect soil structure... Water volumes of 800-1 000 L/ha were commonly applied...

Soils across the northern region are sending a clear message to growers - good seasons and flood events have depleted soil fertility and exhausted soil mineral nitrogen reserves built up during dry seasons of the mid-2000s... Dr Dowling says long term declines in soil fertility came together with short term seasonal conditions to take growers by surprise last year when protein levels came in lower than expected... Dr Dowling says the "set and forget" nitrogen strategy may need to be reviewed as the season progresses to ensure the crop has enough nitrogen to finish well...
