Non-wetting management options (West River - Burrell)

Claying has been undertaken in many areas throughout the zone, and there is quite a bit of expertise on the risks and benefits associated with it within the zone. Cash flow of most farmers in general doesn’t allow the expense of the high rates of clay to occur. However, there is anecdotal evidence to suggest that low rates of clay (lower than rates used currently to improve soil structure) will improve the wettability of the soil. By including clay in the trial it is anticipated that the benefits of low rates of clay will show improved wettability. Other opportunities for the zone appear to be mitigation of non-wetting – including on-row seeding. This would include associated practical risks around seeding such as stubble handling issues and accurate seeding systems.
