Field trials on northwest NSW cracking clay soils (Vertosols) during 2011-2013 showed that surface application of urea led to ammonia volatilisation averaging 11% N loss when applied to fallow soils, and 5% N loss when applied to tillering wheat crops... Compared to urea, losses from ammonium sulfate were less, except when the soil contained >2% calcium carbonate (lime)... At the conclusion of the month, we sampled soils and plants (at in-crop and pasture sites) and measured soil nitrate and ammonium and plant total N. We did not measure N uptake into grain...

Liquid Nitrogen: pros and cons of different formulations.. The use of liquid nitrogen fertiliser is not new to australian grains production... Leaf burn from spotting is dessication to localised areas from too high a salt concentration in the fertiliser solution leading to cell-burst and necrosis, leaf tip and marginal burn is from very rapid uptake and translocation without metabolism of predominantly Urea (can also be from ammonium)...

Barley Yellow Dwarf Virus can be a threat in all environments, and it is recommended that seed be treated with imidicloprid, or crops closely monitored for aphid infestation and sprayed ... In the circumstances using fertilisers that have a higher sulphur content, like MES 10 or Airseeder Superfect, can be beneficial... A fast track project was initiated to demonstrate and evaluate a range of management strategies that Twelve farms were surveyed across the western districts of southern Victoria that were considered suitable as potential trial sites based on grower and adviser recommendations...

In summary, it could be argued that none of the currently available preemergence herbicides have the required stability in efficacy to become viable alternatives to postemergence group A or imidazolinone herbicides... Overall, 2012 seasonal conditions tended to favour early and mid flowering and maturing varieties...
