SURFACE APPLICATION VS. INJECTING. Surface application of nitrogen still works with some no-till situations, but youâ??ve got to be careful how you do it to protect the environment and get full return for each dollar spent on fertilizing.

Reduce Surface-Applied Nitrogen Losses

Make sure you’re getting full value from nitrogen applied to your no-tilled crops.

When it comes to surface-applying UAN solutions or urea, it’s easy to end up with considerable losses due to volatilization.

Check the management ideas No-Till Farmer readers are using to reduce this costly loss of nitrogen while taking steps to protect the environment.

—Ed Ruge, Valparaiso, Ind.

  • “Hold off spraying liquid nitrogen until 1 to 3 days before a predicted rain.”

—Mark Kessler, Crawfordsville, Ind.

  • “Early nitrogen application with Agrotain works best for us.”

—Paul Hay, Beatrice, Neb.

  • “Because of nitrogen volatilization, I no longer use urea or liquid nitrogen.”

  • “Apply before it rains with a nitrogen stabilizer.”

—Joel Myers, Spring Mills, Pa.

  • “Apply nitrogen early in the spring before it rains (which will incorporate it) and before temperatures get high enough to volatilize it.”

—Doug Coffrey, Thornton, Ind.

  • “I add Agrotain when I surface-apply nitrogen and inject with a coulter when sidedressing.”
