The perception that a no-till system would lead to greater herbicide resistance
problems was widespread. Awareness of the potential erodibility of farm soils
was also high; however, neither of these factors was influential in determining
whether growers were adopters or non-adopters at the time of the study.
Research and extension efforts demonstrating soil erodibility and its prevention
under no-till are likely to be less effective at increasing the likelihood of no-till
adoption than a focus on early season weed management options and the
opportunities for timelier seeding under no-till cropping systems. The study
provides evidence that adoption of no-till systems is an information-intensive
process and that there are likely to be opportunities for extension and localised
information to accelerate the use of no-till by Australian grain growers.
