Soil organic carbon makes up about 58 per cent of the mass of organic matter and is usually reported in a soil analysis report as the concentration (i.e. per cent) of organic carbon in soil (see Chapter 1 for more detail)... If a soil has a significant amount of gravel or stone material, this fraction is removed before analysis with the final soil carbon or nutrient assessment being only representative of the mineral component of the remaining soil... Understanding how organic matter cycles through the soil and what drives its accumulation and loss is critical to maintaining it at optimal ...

In summary, 20 trials have now recently been undertaken across a number of seasons and locations in NSW. None of them have demonstrated S responses in yield or oil %. This does not exclude deficiency and yield penalties from occurring but does highlight that the frequency and the likelihood is not high... In summary, using Yield Prophet as a way of increasing soil water knowledge is more difficult to trial than probes... In summary, the growth in the use of probes to understand soil water is easily explained using the framework above...

Old leaves develop elongated grey to dark brown spots on or near the edges of the leaf, usually half way along the leaf quickly spreading towards the tip and base... Description Old leaves turn pale green and bronze-yellow areas develop in the mid-section of the leaf between the edge and mid-vein; these areas quickly extend towards the leaf tip until the top two-thirds of the leaf is bronze-yellow (orange-red in some varieties)... Old leaves become dull green and bronze-orange areas develop between the edge and mid-vein at the base of the leaf...

Researchers anticipate an increase in resistanace to Group B 'imi' herbicdies (e.g. Intervix in annual tyegrass and brome grass in cropping areas as the number of different Clearfield (insert registration symbol) or imi tolerant crop options grows... For tillage situations, 1.6L/ha of Avadex Xtra and 1.5L/ha of trifluralin are commonly used in canola, dependent on soil type (note these rates are too high for cereals)... the sole reason i am using the long fallow followed byrr canola is weed control...
