Corn Ammonia Injury

Tritten

MISSOURI, STATE (2010-4-26) Missouri corn growers will want to be careful this year when planting the crop after ammonia application.

Most ammonia injury to corn occurs in dry conditions, but wet soils can also lead to ammonia hurting seedling corn. Keeping the ammonia depth at 6 to 8 inches and waiting 7 to 10 days after application is usually a good rule to follow. Corn ammonia injury can be identified if the corn seedling roots look like they have been burnt.
