Research aids decisions on fertiliser application.. Conversely calcium carbonate content did not affect losses from urea or other nitrogen fertilisers trialled so growers with high calcium carbonate content soils will incur less risk by tailoring their fertiliser type ... As a high input cost, fertiliser selection and application need to be managed well if growers are to maximise crop returns and this type of research is a valuable step forward in enabling industry to achieve that goal...

The availability of shallow nutrient reserves can be severely compromised by dry soil in those layers during critical uptake periods, while deep-sowing techniques can place seed at the bottom of, or even below, the soil layers upon which fertiliser recommendations were derived... The capacity of the plant to take up potassium is not directly related to potassium in solution... The frequency distribution for the 810 trials evaluated...

Supported by Research Update sponsored by.. o Volatility will be high o Impossible to pick the top of the market o Set price targets and stick to them o Volatility will give good chance for forward contracting o Consider looking two years ahead as prices are higher there as well o Some forward contracts allows flexibility around delivery o SWAPS are likely to be attractive - IF used correctly o Take quick action if crop starts to deteriorate o Evaluate counterparty carefully in these volatile times 2013 Moama GRDC Grains Research Update for Growers 25.. Choosing the right canola variety for your farming system involves identifying what maturity you need, selecting the right herbicide tolerance (if any) you want, considering the blackleg resistance you require, and then seeing your reseller to determine what seed they have that matches your needs...

The early research also showed that in dry environments the changes in total soil-N were equal to the N removed in crops, but in wetter environments there was more loss of soil N than removal of crop N, probably because of loss of soil N due to denitrification... Many of the long-term experiments discussed earlier showed that introducing pastures into the rotation stabilised the soil total N...

Soil profiles were assessed for stratification of plant-available phosphorus (P) and potassium (K) and presence of additional plant-available reserves not measured in commercial soil tests... The project has shown that P pools other than that measured by Colwell P are making a significant contribution to meeting crop P requirements, although whether in the current crop or by replenishing Colwell P for the start of the next crop is not clear... Glasshouse studies confirmed the availability of acid and residual P pools for crop uptake but further work is needed to determine: the form of these reserves an appropriate diagnostic test to quantify them the rate of release for crop uptake...

Nitrogen fertiliser losses from the soil as nitrous oxide gas can escalate following summer rain post-harvest in Western Australia... JJ In trials at Hamilton, Victoria, between 80 and 90 per cent of applied N was unaccounted for at harvest where urea was deep-banded 10 centimetres below the seed at sowing in soils that became saturated or waterlogged during the growing season... Trials examining legumes and canola in southern NSW found these crops used most of the mineral N available in the soil during the growing season and, as a consequence, N2O emissions mostly occurred following harvest during the summer fallow period when N was mineralised from crop residues...

Gross margins achieved on-farm for wheat in 2011 may have been lower than shown in Table 2... The gross margin calculations depicted in Figure 5 assumed that canola yielded 50 % of wheat at that site in that year... In comparing while many farm decisions are made intuitive versus logical analytical under the influence of a DSS which provide learning reasoning he suggests the either/or approach to on a topic, they are not necessarily used every time the dichotomies is destructive and goes on to say a decision is made...
