Catalogue: Ground Cover
A high proportion of phosphorus applied to these soils can remain inaccessible to crops... Phosphorus derived from the fluid form occupies a larger volume of soil surrounding the fertiliser, which increases the likelihood that roots will come into contact with the nutrient... Shoot response of wheat to fluid fertilisers (APP and H 3 PO 4 ) compared to granular fertiliser (Triple P) and a control growing on a Vertosol collected from Minyip in the Wimmera under glasshouse conditions...

GRDC values the contributions made by its research partners during the 2004 series of Grains Research Updates.. Overall, there were 50 comparisons, 45 showing a positive yield increase with fluid and 5 with no yield difference... Overall, there were 11 comparisons, with 4 yield decreases due to fluids and 7 with no yield differences...

Identify where the benefits of fluid fertilisers are likely to be significant, in terms of climate, soil type and cropping system... The conclusion is that while there does not appear to be any yield advantage associated with using Flexi-N through the boom, as opposed to urea topdressed prior to sowing, there does appear to be an advantage when it is banded... The freight was approximately $40/tonne, compared to solid fertiliser delivered bulk, which is approximately $20/tonne...

Catalogue: GRDC Final Reports
The mechanisms responsible for effectiveness of fluid fertilisers in calcareous soils, and the ineffectiveness of granular P, were identified chemically and spectroscopically... Field experiments on calcareous and non-calcareous soils in the Victorian Wimmera and Mallee regions have also shown that fluid fertilisers can improve grain yields on these soil types, although the magnitude of grain responses were usually smaller than on the highly calcareous soils in South Australia... There is a growing demand for information on fluid fertilisers and their use in cropping in Australia, as demonstrated by the increasing hits to the fluid fertiliser website, and the growth in circulation of the Fluid Newsletter, and the popularity of the Fluid Workshop held in 2004...

Based on this, we estimate that water used by weeds in the wet weedy (+I+W) treatment up to the midfallow period was 593 x 1688 (biomass) / 10 000 = 100 mm; for the dry weedy (-I+W) treatment water use is estimated at 30 mm... The results showed that Zn uptake by plants and in the grain could be most improved by mixing Zn with N and P (as technical grade MAP and ammonium nitrate dissolved in water) in a single solution and injecting it into the soil to a depth of 40 cm... Results from our laboratory experiments have confirmed that fluid forms of P have very different physical and/or chemical effects on soil in the fertilizer band in calcareous soils, and improve plant P uptake...
