What's in a name?
Terminology in relation to tillage practices varies around Australia. A consensus of opinion among Australian agronomists and researchers indicates that 2-3 cultivations prior to sowing are not considered excessive, and may even constitute minimum or reduced tillage in NSW and Victoria.
