Overall, 60-70 per cent of flour is used in traditional flat breads, 20-25 per cent of flour is used in western style breads and 5-10 per cent is used in cakes and biscuits... In summary, canola varieties sown 2-3 weeks earlier than normal (early to mid April) can be grazed in winter prior to bud elongation (usually providing 600-800 dse grazing days/ha) and recover with no impact on yield or oil...

Western Australian researchers investigating biochar have unearthed some promising results about its properties... UWA Institute of Agriculture Associate Professor Daniel Murphy, who is leading WA research under the GRDC biochar project, said new studies had also shown that biochar did not affect the rate at which nitrogen was released from the decomposition of organic matter in soil... "Biochar is a stable form of carbon which can remain in the soil for hundreds of years - we need to be very sure about its attributes before making recommendations about its use," Professor Murphy said...

A Western Australian study shows that applying biochar made from wheat chaff and eucalyptus wood may have some negative effects on sandy soils.. To assess the impact of biochar on nitrogen leaching in a sandy soil from Meckering, WA, Mr Dempster ran another glasshouse trial and compared the results to those achieved by adding clay - another ameliorant being used by some growers to enhance soil fertility... The results showed yield decreased significantly from 2.1t/ha to 1.7t/ha when biochar was banded into the subsoil...

Although biochar addition to soil did decrease inorganic N leaching, soil N mineralisation either decreased or did not change... The application of pyrolysed organic matter or biochar to soil can remediate decreased SOM and sequester C. The application of biochar to soil has also been shown to improve soil fertility and enhance yields of crops such as maize, wheat and peanuts... As biochar addition to soil can increase microbial community size and activity, previous research has hypothesised that this mechanism may be responsible for enhanced N mineralisation rates and contributes to the demonstrated improvements of N fertiliser use efficiency (up to 90%) in glasshouse-based agronomic research...

[Photo (left) by Evan Collis: Ian Stanley is trialling biochar made from wheat straw to improve the condition of his sandy soils.].. Working with Professor Syd Shea of Notre Dame University and independent Melbourne engineer and businessman Peter Burgess, Mr Stanley has been trialling biochar - a fine-grained charcoal high in organic carbon, thought to improve soil fertility - for the past four years... "We have a no-till operation and apart from its small value as a ground cover, wheat straw has no value, so biochar made from this could provide farmers with another source of revenue," Mr Stanley says...

Based on the data, a number of biochars will be selected for detailed field and laboratory-based experiments to assess the different aspects of the biochar on crop nutrition and associated soil properties... The project (in collaboration with project CSO00041, Evelyn Krull CSIRO) uses a combination of fundamental and applied experiments to assess the potential fit of biochar into current and future farming systems with a particular focus on plant nutrient acquisition... 4) A web-calculator to assess the effect of biochar on crop productivity Research iIn conjunction with the DAFF national biochar initiative, the project team assembled over 80 different biochars (from different sources and produced under different temperature regimes) which have been analysed for various functions, such as C content, pH, CEC, adsorption capacity, stability, water-holding capacity, porosity and specific surface area...

Based on the data, a number of biochars will be selected for detailed field and laboratory-based experiments to assess the different aspects of the biochar on crop nutrition and associated soil properties... Organic manures and green waste materials show promise in augmenting the use of mineral fertilisers in cropping systems, whilst the use of biochar may have a role in sequestering carbon and improving the nutrient retention capacity of soils...

The likely economic costs and benefits of changing management to sequester and maintain more carbon (C) in soils; sequestering C in vegetation by planting woody perennials; producing feedstock materials for conversion into biochar or; using the same feedstock material to generate biomass energy will determined by modelling them individually using applicable biophysical and economic coefficients... This will reveal the most financially attractive package of actions for farmers to mitigate GHGs, likely changes in enterprise mix and how the profit and net emissions for the whole farm may change for different prices of C, both with and without the inclusion of agriculture into policies aimed at reducing the emissions... A feature of the study will be the comparison of sequestering C in vegetation or soil (options that require on-going management and measurement whilst also encumbering the farmer with liability and increased risk for potentially 100 plus years) with the more "once-off" options of biochar and biomass energy production...

The research has shown that biochar additions to soil can decrease the rate of nitrogen mineralisation, the size of the microbial biomass and also the amount of nitrogen leaching... The results of a field trial studied in this research has shown that early in the season, more nitrogen was available to the plant early in the growing season...
