(FARMING—WESTERN AUSTRALIA) Doug Pow is a farmer from the lower South West of WA. He was a pioneer of the Marron (freshwater crustacean) industry. That entailed a thorough analysis of the local climate. As a result he planted the first avocados in the lower South West, his study had been in botany, not aquaculture. The avocado industry in the lower South West of WA is now worth $100’s of millions per year. Four years ago he began experimenting with the application of biochar to beef cattle husbandry with profound results way in excess of the original aims, both biologically and economically. Last year the application of biochar has been applied to the culture of avocados on an industrial scale, with the aim of creating a soil more closely approximating the physical properties of the volcanic andisol soil that the avocado evolved in. His experiments with the application of biochar over the last four years have been a continuation of 40 years of adaption to a changing climatic and economic environment.


(SUPPLY CHAIN & POLICY -QLD) Kelly Bryant (Australian Biomass for Bioenergy Assessment, Queensland project officer) I have been working as a soil scientist with the Queensland Government for the past 10 years within the landscape sciences division. I have been involved in a diverse range of work across Queensland from Digital Soils Mapping (using remotely sensed data to model soil attributes), developing indicators to identify wetland soils, salinity risk assessments to writing websites on soil management. In the last 5 years I have also been heavily involved in the Queensland Government Open Data initiative. This initiative aims to make all Qld government data available online and in accessible formats through various platforms. I am currently working with other state teams across Australia to deliver consistent and publically available information on biomass feedstocks through the Australian Renewable Energy Mapping Infrastructure online platform, as part of the Australian Biomass for Bioenergy Assessment. This assessment will assist project developers make decisions for new bioenergy projects, and provide linkages between potential biomass feedstocks – through the supply chain – to end users.

Dr Paul Taylor (Applied Science – NSW) graduated with the University Medal in physics from the University of NSW, recieved a PhD from UNiviersity of Colorado, and worked at Harvard Smithsonian Astrophysical Observatory and MIT. He now lives in both Australia and the U.S., researching and presenting on biochar and climate change.

Don Graves (Applied Science – N.Z.) Don lives in Motueka New Zealand where he’s a plant biologist and soil ecologist specialised in mycorrhizal fungi, revegetation, soil regeneration, cover crops and other conservation agricultural tools including no-tillage and biochar. Don’s research also includes traditional Māori gardening tillage practices, & pre-colonial charcoal soil amendment practices that produced 1,000s of hectares of distinctively dark coloured “para umu” soils. Biochar is an important aid to soil carbon sequestration, nutrient retention, soil structure and soil biological fertility. Don’s research is primarily focus in mycorrhizas and the soil zone adjacent to plant roots has led to pyroneering research using no-tillage direct seed drill technology and ‘no-dig’ seedling transplanting methods to provide the optimal location for biochar to benefit plants and mycorrhizas; and conversely biochar placement to optimise the benefits of root exudates to benefit biochar and the soil biota it can contain.  Don’s work was published in a 2013 CRC Press book chapter titled “A Comparison of methods to apply biochar into temperate soils”, in “Biochar and Soil Biota” .  See
