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...

Climate variability (inter- and intra- season rainfall and temperature patterns) and prices received for grain of a particular quality make it very difficult to offer serious strategies to optimise profitability in the short term... There are two periods of the year when nitrogen application offers the greatest likelihood of recovery of applied nitrogen in winter cereals: around the end of the calendar year and in July (GS 3.2) according to studies over approximately 10 years starting in the late 1970's, over six No-Till sites in by Felton and Marcellos... Nitrogen costing about $1.40 per kilogram, operating costs greater than $310 per ha, grain yields averaging 2.2 tonnes per ha and grain prices sub- $180 for grain (at depot), make it difficult to 'make ends meet'...

The project has focused on the main cropping soils of southern Queensland, where unpredictable responses to applied phosphorus fertiliser in grains and pulses are continuing to be recorded... Fifty per cent of phosphorus removed comes from below 10 cm... Phosphorus applied with seed only supplies approximately 10% of crop needs...

Fertilisers have traditionally represented a significant part of the variable costs of growing crops in Australia... The expected outcome of this project is best nutrient management strategies evaluated in the context of a risk-return framework... Assuming farmers are profit -maximizers and risk-neutral, this analysis shows that they are likely missing out on the better seasons by under-fertilizing in sandy dunes and mid slopes of several sites across the Mallee...

Fertilisers have traditionally represented a significant part of the variable costs of growing crops in Australia... Whether fertiliser input can be sustained is under question because the profitability of fertiliser use by grain growers is undergoing considerable change... Although the cost of fertiliser has receded from peak prices, the recovery of the world economy is expected to place upward pressure on energy prices in the future...
