01 / The question
Can winter-terminated cover crops support nutrient cycling and soil cover in northern vegetable systems?
02 / In the field
Borderview: 17 treatments plus control, four replicates. River Berry: three treatments; Pomykala: four; three replicates each. Soil nitrate, biomass and crop responses tracked.
Reported study period: 2017-2018. Study years and award years may differ.

03 / What the project reported
No significant sweet-corn yield differences were reported at Borderview and Pomykala.

04 / What it could mean for farmers
Match cover-crop winter survival and planting date to the following crop. Treat these findings as one-season evidence.
OpenAgData interpretation of the reported evidence.
What remains unresolved
Strawberries at River Berry were not due for harvest until 2019; the broad summary does not establish a yield result there. Longer-term soil-health effects remain unresolved.
Research & outreach outputs
Research reports and a vegetable cover-cropping bulletin.
A question for review
Is the narrower yield statement appropriate, given the unharvested strawberry crop?
