KEY LEARNS FROM
BARTON BLACK-GRASS
INNOVATION CENTRE
SO FAR
1. KNOW WHAT YOU’RE UP AGAINST
The key insights from Barton come
from overlaying weed control tactics
over multiple years, and monitoring
both weed control and margins.
The site is now in its fourth year and
we have begun to establish some
interesting principles.
CONSIDER:
IMPLICATIONS:
•Where is your weed seed in the
soil profile?
• What is the resistance status?
• What is the dormancy level?
• Informs cultivation decisions
•Establishment method impacts
herbicide strategy
At Barton, in our matrix field, we have crossed both cultivation technique and
crop species to look at the effect of these factors across the rotation. The
plan below shows years 1-3. The work will continue for 5 years to enable the
effects of the rotation to become evident, for both grass weed control but
also margin over input costs across the rotation.
