Catalogue: GRDC Updates (North)
In summary VSAP is: A summary of the key reasons for the release of the new variety, including strengths and weaknesses, and how the new variety should be managed relative to current common varieties... Overall, Total N fixed was strongly linked to dry matter production and rainfall... Overall, early removal is still likely to be the best option on heavy clay soils...

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...
