Planning S fertilisation for maintenance levels of 4 kg to 5 kg S/t of grain removed might be more suitable as a general rule... Canola requires higher inputs per tonne of grain for the major (macro-) nutrients N, P and S compared with other crops (Table 1)... Table 1: Comparison of the average quantity of major nutrients removed (kg/ha) per tonne of grain and stubble for a range of crops, including canola and wheat...

Early work on canola focused on weed management strategies including the breeding of herbicide tolerant canola varieties such as triazine tolerant (TT) varieties which now account for an estimated 90% of canola grown in WA... Research is still being conducted to determine the effect of these viruses on the yield of canola in WA. European work has found seed yield losses of 10-15% associated with this virus disease in canola... The amount of air passed through the grain is measured in litres per second per tonne and varies depending on the particular aeration strategy...

Ongoing soil fertility research shows testing deeper in the soil profile can provide clues to the fertiliser needs in the top 10 centimetres... Dr Bell says decisions on how best to respond to low soil fertility depends upon how many nutrients appear limiting and which nutrients they are -- mobile nutrients such as nitrogen or sulfur will need different application strategies than immobile nutrients like phosphorus and potassium... Dr Bell says the testing limitations are more evident when samples are assessed only in the top 10cm of the profile, as this layer does not provide a good enough estimate of fertilitY - either of immobile nutrients like phosphorus and potassium, or of mobile nutrients like nitrogen and sulfur...

Canola N strategies may need rethink.. Grain Orana Alliance chief executive officer Maurie Street is encouraging canola growers to reassess their approach to N management and investment to avoid leaving valuable yield "in the paddock"... "After running these trials and seeing the response to what would traditionally be considered very high rates of N, it's now my belief that many growers could be leaving a significant amount of yield in the paddock due to lack of N...
