Nutrition Issues for 2011 Bruce Ramsey, AgriTech Crop Research, Wagga Wagga After a decade of seasons; peppered with drought and heart breaking "bob tail" springs, finally we have now all experienced a wet season... The wet season in 2010 and the 2011 summer may have leached sulphur down the profile and out of the root zone... Trace elements are best identified through plant tissue analysis and addressed ...

The recent spate of hot weather coincided with a critical development phase for many crops and growers are being warned that heat can have severe impacts on yield, even in crops that are not moisture stressed... Backed by the Federal and Queensland Governments and the Grains Research and Development Corporation (GRDC), the research found the most severe impacts on yield occurred when high temperatures around flowering reduced the viability of sorghum pollen resulting in reduced seed set... Dr Jordan said the impact of the recent high temperatures on individual crops would vary depending on the growth stage of the crop, varietal sensitivity and the duration and severity of the high temperatures, and that on-going management decisions would need to be made on a case-by-case basis...

The Northern Grains Region broadly consists of soils with inherently high fertility and water holding capacity... Possible reasons for the difference between achieved and potential grain yield have often been reported individually but rarely collectively and never specifically allocated to particular management practices... This project aims to determine the maximum attainable (potential) grain yield (wheat and sorghum) for a given year at two core nodes across the NSW component of the Northern Grains Region; Trangie (CW NSW) and the Liverpool Plains (NNSW)...

Quirindi Grains Research Update Nutrition on black soil.. Grains Research Update - Quirindi August 2002 there is drought prior to flowering and a low number of kernels are set then the kernels which are produced will tend to be larger... In summary controlled traffic and conservation tillage will assist in protecting the surface of the soil and will maximise the activity of soil animals, increasing the infiltration and the water holding capacity of the soil...

Pasture leys, legume rotations and fertilisers all can have important roles in maintaining the chemical, biological and physical fertility of soils... For example if 40 kg N/ha is required, this rate of nitrogen can be supplied by applying 87 kg/ha of urea... Copper deficiency can be corrected by applying copper sulphate either to the soil as a fertiliser or to the foliage as a spray...

While chickpeas are considered to have moderately high requirement for P, economic fertiliser responses to P are uncommon... The two exceptions are: soils with critically low P levels (below 6-8 mg P/kg, based on a Colwell test at 0-10cm) and no prior history of P fertiliser long fallow situations with low VAM levels (10 months or longer) even where soil levels are considered adequate... Some situations where N fertiliser may warrant consideration include: late plant situations where the crop can flower as quickly as 60 days, and rapid early growth is critical in achieving adequate height and sufficient biomass to support a reasonable grain yield...
