    Safe to spread urea on 5 leaf wheat?

    Had a little rain lately and was wondering about floating on urea in about 10-14 days if rain is forecasted. Thinking wheat will be 5-6 leaf. Can I safely float on granular urea or will the granules fall down in the bottom of the leaves and damage the plants?

      I would not worry about that, it is more critical getting it down and not having it evaporate before a rain. Definitely treat with agritain.

        U will be fine. Have done it a few times and try to time it with a rain in the forecast. This year is a crap shoot on the reliability of rain events so adding a stabilizer would be good insurance.

          Maybe I’m talking out my hat but if you’re going for yield isn’t 5 leaf too late? I was always told to get it on before 4 leaf for yield and after for protein.

            I will have to look into the yield part. Was thinking that slightly later would maybe reduce the lodging potential.

              I spread on Durum around that time and it turned the darkest green of any wheat I have ever grown. Looked amazing. Unfortunately all went to protein and not to yield. I still remember taking it to Gardiner Dam and they thought something was wrong with their tester because it was 17.2-17.4 protein. Of course this was in the CWB era and I got essentially nothing for my troubles.

                Perhaps spraying uan is better

                More research looks like spraying on uan at the end of tillering would be more consistent.

                I have lots of hills and the spray booms move up and down 6’ at times. Not sure if the crop injury would be a problem or not? At 6’ above the crop there will be a lot of overlap on some of the fertilizer streams.
