Nitrogen Recommendation:
Nitrogen Recommendation Preview:
plus or minus 20 pound N per acre.
Nitrogen Recommendation After Credits:
plus or minus 20 pound N per acre. The final N recommendation is an average optimal rate. Your final N rate decision may be plus or minus 20 pounds N per acre from that value depending on individual field situations. The value assumes an optimal N application and timing strategy. If these strategies are not optimal, a greater N rate maybe needed. Suboptimal N application strategies include to early N application the fall prior to seeding, surface urea/UAN application or lightly incorporated urea/UAN, or shallow ammonia application. Fields that are first year sunflower, or sunflower more then 4 years after a deep rooted crop including sunflower may have have deep N, and a minimal N preplant application followed by side-dress application at V5-V8 is recommended. |
