Founder and Director of the Maximum Soil & Water Productivity consultancy company (see website https.//www.maxswp.com.au)Inventor of the Deep Blade Loosening machine that deepens and optimises the physical, biological and fertility conditions of root zones and increases productivity of soils. The machine has been field-tested across Australia and Pakistan.Highly successful career in researching and applying soil physics theory to improve the management practices and productivity of agricultural soils.Career firsts:• Used field-measured soil properties to verify soil physics theory of capillary rise from shallow water tables for the purpose of reclaiming saline soils• Used field-measured soil properties to verify soil physics theory of rainfall infiltration for the purpose of predicting rainfall infiltration and demonstrating the effects on it of soil management practices• Used rainfall infiltration theory to predict runoff of storm rain for the purpose of designing earthworks to control and safely dispose of runoff• Demonstrated how permanent raised beds (PRB) prevent winter waterlogging of cereal crops in Western Australia• Drove the adoption of PRBs to prevent winter waterlogging in the WA wheatbelt to ~ 400,000 ha• Used soil drainage theory to demonstrate how improved soil management would allow PRB to be as wide as 3m and still drain quickly enough to prevent waterlogging• Used soil physics, soil engineering and soil management theory to design an energy-efficient Deep Blade Loosener (DBL) machine• Demonstrated how the use of the DBL machine generates sustainably large increases in soil organic carbon and the productivity of compact and sodic soils• Introduced PRBs and improved soil management to Pakistan to increase irrigation efficiency and productivity - currently ~ 500,000 ha, and expanding• Used soil physics theory and the DBL machine to sustainably improve soil organic carbon, productivity and irrigation efficiency of all forms of irrigation on a wide range of soils across Australia and PakistanOther Notable Career Achievements• Managed the Remnant Vegetation Protection Scheme in Western Australia• Director of Greening Western Australia for five years• Lead organiser of two nation-wide conferences – 5th Australian Soil Conservation Conference and the 2005 Australian Controlled Traffic Farming ConferenceAwards• BHP-Billiton Award for Western Australian Landcare Research• Runner-up in National Heritage Trust National Landcare Research Awards• Agriculture Western Australia Award for Innovation and Technical Excellence
