About us

Bill Crabtree

B.Ag.Sci., M.Sc. UWA, Cert. IV TAA. McKell medal 2009.

Bill Crabtree
Known as "No-Till Bill" for his enthusiasm for no-tillage and the role he played in the Western Australian no-tillage revolution. Bill began his career with the WA Dept of Ag as a researcher into "Minimum tillage for wind erodible soils" in his home erosion-swept town of Jerramungup.

Now Jerramungup is a leader in the adoption of no-till cropping systems. He then extended this work to farmers in Esperance and the rest of the state which led to him receiving the Landcarer of the year award in WA in 1996.


Bill spent a year in Canada in 1996, learning how they do no-tillage. While there he co-edited their book Advancing the Art of Zero Tillage which is on the ManDak website.


He returned to WA as the Scientific Officer for the WA No-Till Farmers Association for a five and a half-year term.

Consultant and farmer

Bill is now a consultant specialising in no-tillage technologies based in Cannington WA. His home state now boasts an 90% adoption of no-tillage and no-tillage has dramatically improved WA's production, especially in the recent droughts.

Bill received the prestigious GRDC's Western Panel Seed of Light Award in 2006 for excellence in communication. This was particularly for the role in extending information on no-tillage and biotechnology.

In December 2007, Bill purchased 3,200 hectares of York Gum farmland at NE Morawa and has been working closely with his older brother Geoff.


In March 2011, Bill spent a month in NSW, Victoria and South Australia providing Sustainable Agriculture workshops to groups of local farmers. He said it was interesting seeing first hand the effects of the flooding, droughts and pest issues for the 2011 growing season. He also sold 80 books.


In April 2011 Bill travelled to Namibia to visit farmers and to speak at the Namibian Farmers' conference. He enjoyed learning of the challenges of farming in western africa and found the locals very hospitable.

In Jan 2012, Bill travelled to North America to speak at three different farmer conferences and was well received. He travelled with the then WANTFA president, Wes Baker. Together they drove across the frozen Canadian prairies visiting agricultural industries and meeting some wonderful people along the way.

2013 has seen Bill speaking on the limitations of cover crops in dryland agriculture. He spoke on this topic in ‘No Till on the Plains’ conference in Kansas in January, and at the AAPRESID international conference in Rosario, Argentina in August.

Bill and farmer friend Rod Birch travelled on to the Cerrado, near Brasilia, in August to view the new farming land of Brazil and to see the array of crops being grown there (see pictures below).

In August, 2016 Bill spoke at AAPRESID conference in Argentina on ‘Experiences with rotations and cover crops in a dry Australian environment’. His full talk is available here.


Bill also plays guitar, has completed 3 Avon Descents, walks with Monique and is an active member of the Liberal Party.

The late James Crabtree

"James Crabtree, my dad, who passed away at 94 years of age in March 2012, also helped me get into farming", Bill Crabtree.


Bill is on the Grain committee of the Pastoralists and Graziers Association of Western Australia (PGA) and is the WA representative of the Producers forum.

Bill is involved in ArCham (Argentine Chamber of Commerce in Australia).

Further studies

In October 2015 Bill commenced his PhD studies in ‘The History of No-Tillage Adoption in Western Australia’ at the UWA Faculty of Science.
