Wheat School: How to avoid leaf burn by UAN


Wheat costs are wonderful and everybody desires massive wheat yields this 12 months. So, how do you obtain them? By paying shut consideration to your nitrogen purposes, after all.

Peter “Wheat Pete” Johnson is hopping mad on this Wheat College episode — mad at himself that’s. Within the video, he’s standing in a wheat subject with leaf-burn — a subject that he mentioned was good-to-go.

“Split your nitrogen, because we’ve got a big wheat crop in the ground and we want to make sure we keep it standing; we don’t want it to fall over,” says Johnson. Nevertheless, low temperature nights, cloudy days, and the truth that the leaves don’t have a cuticle, may cause horrible leaf burn from 28 per cent (UAN) on a second utility, he explains.

So what can we be taught from the sector Johnson’s standing in? Selection makes a distinction — a range with a prostrate leaf that leans out and tries to cover over will burn worse. Streamer nozzles additionally make an incredible distinction, says Johnson, explaining that nozzles that shoot straight down will trigger uniform burn (which isn’t nice, after all).

Johnson warns that white frost acts like glue for UAN on the leaf, and that doing all your N utility when there’s a dew additionally doesn’t work. The appliance wants to be completed when the plant is dry or when it’s raining.

Dilution can also be key, says Johnson, advising utilizing one half water to one half UAN. Lastly, Johnson says that fortunately the yield impression will likely be fairly small, although photosynthetic space has been compromised.
