- reduced tillage - one pass of full soil disturbance prior to seeding;
- direct drilling - one pass seeding with a full-cut or greater than 20% topsoil disturbance;
- no-tllage - knife point or disc seeding with 5 - 20% topsoil disturbance; and
- zero-tillage - disc seeding without soil throw (but note that some discs do throw soil) (Crabtree 2010 Search for Sustainability page 9)
Bill wins McKell Medal |
23 April 2010: The Hon. Tony Burke MP, Minister for Agriculture, Fisheries and Forestry presents Bill Crabtree with the 24th McKell Medal at the Natural Resources Management (NRM) Ministerial Council Meeting in Darwin.
“Mr Crabtree’s knowledge and enthusiasm for promoting sustainable farming practices and mitigating soil erosion is highly regarded.
“As a scientist, Mr Crabtree has published significant scientific data and has worked closely with leading farmers to extend his knowledge to the broader farming community over the past 25 years.
“Through his work, he has been able to encourage farmers to adopt no-till farming systems that improve soil structure and nutrient recycling, and reduce soil evaporation, wind and water erosion” said Mr Burke.
The McKell Medal is awarded annually by the NRM Ministerial Council to recognise outstanding achievements in shaping community attitudes and practices in natural resource management.
The medal honours the contribution to soil and land conservation of Sir William McKell, a former Governor-General of Australia and Premier of New South Wales.
