Late-Season Nitrogen Applications Hit the Sweet Spot

WinField research teams plant competitor products, partner products and WinField products in side-by-side trials over multiple seasons, then evaluate these data points at local, regional and national levels from 191 locations across 32 states. This impartial testing provides comprehensive data you can use to confidently make decisions for your own operation.
Over the coming weeks, we will share some of the more significant insights derived from our 2015 Answer Plot® Program, such as:
Trials showed a positive yield response to split-season and late-season nitrogen (N) applications made at critical corn growth stages.
Methodology
Researchers compared three application scenarios
- Total N allotment applied at planting
- Two-thirds of N allotment applied at planting, one-third at V10
- Total N allotment applied at planting, followed by additional N at VT
Results
- Total N allotment at planting: 235.9 bu/A
- Split application at planting/V10: 245.3 bu/A (Average yield increase of 9.4 bu/A)
- Total N at planting, then additional N at VT: 247.1 bu/A (Average yield increase of 11.2 bu/A)
Bottom line: Strategic application timing can help eliminate the financial and environmental costs of applying excess nitrogen, and result in additional bushels.
