Urea

[rex]

It has been a pretty wet year here in North Central Texas this year. I have been trying to get my haygrazer in the ground but it has been too wet and it is getting late. It is supposed to rain again so I just went for it and sowed it on Sunday. I intended to disk in urea first but didnt have the time and couldnt get it on Sunday anyway. The ground is still pretty damp. Can I spread urea on top of the ground without losing too much? (supposed to rain tomorrow night) If it doesnt rain for a week how much of it would evaporate? (in the 70's to 82 this week) Anybody have any suggestions? This is in blackland. Thanks

Soil temperature is what matters. They claim you can loose up to 50% if the soil is warm and dry. I think a 10 to 20% loss is more typical with urea. If you can use the sulfur I would consider aluminum sulfate rather than urea form of nitrogen.
