Default RE: Urea fertilizer

It's raining today! Thanks Adam!

Dan, I would have incorporated the lime in last fall, and 100-200 lbs/a fertilizer (maybe 19-19-19, depending on the soil test) this spring the day of planting as a starter for the corn. That would be my suggestion for future corn plots. Lime can tie up fertilizer, so do not apply both on the same day this year.

Do you have a soil sample? If not, what kind of area are you planting? If it was a high fertility field used by a farmer last year, I would use the 100 lbs/a 19-19-19 when the corn is emerging. If the plots are cut out of a forest or low fertility ground, I would add 200 lbs/a of 19-19-19. I would still add urea, so the corn gets at least 100 lbs/a of N (120-150 lbs/a N is even better, depends on your budget). Use the calculations above to determine how much urea you need to apply. You get 19 lbs/a for each 100 lbs/a of 19-19-19 you add. Applying the urea when the corn is 6-12 inches is still the best time for urea.

If you do not have a soil sample, take one in early fall. For best results, send it to your state University or an in-state ag soil testing lab. You can adjust future fertilizer blends and rates on the results. Feel free to ask about the soil results and/or fertilizer recs if you do have questions.

I hope this helps, and I hope the corn work well for you!
