Spoon-feeding nitrogen makes agronomic and economic sense. These guidelines will help you get the best return on your nitrogen investment.

Sidedress corn at the V5 to V6 corn stage (five or six collared leaves), when the plants are about 20 inches tall, says University of Minnesota Corn Specialist Jeff Coulter.

Heavy spring rainfall does not automatically indicate a heavy nitrogen loss if soils are below 50° F, according to University of Minnesota research.

Skip-row sidedressing works because a relatively small portion of corn roots can absorb all the nutrients, according to the University of Illinois. Because the method supplies nitrogen on one side of each row, injecting nitrogen between every other row maintains yields while reducing power requirements, and increasing maneuverability between rows can cut compaction.
