Preliminary Study ConclusionsResponse to strip-tillage may be variety sensitive.
For most crops investigated in this study strip-tillage led to a 20% to 30% increased plant population at emergence than no-tillage.
Strip-tillage warms the soil which provided a 15% to 35% yield increase in early spring planted leafy greens and vegetables.
Strip-tillage eliminated the cover crop competition, which led to robust seedling growth.
Preliminary Study ConclusionsEarly pre plant burndown (EPP) of the cover crop is recommended when soil moisture is limiting. During drought conditions EPP one week prior to planting for each foot of cover crop canopy.
EPP of cover crop will also reduce the chance for seed germination inhibition due to allelopathy.
No-tillage may be more cost effective for summer vegetables with fast germination and quick seedling growth.
