Excellent posts Bruce. Some refuse to understand that university recommendations are usually for broadcast with volatility and tie-up figured in. Also, spring application of fert. should increase efficiency 10-15%. It's hard to justify putting on extra high price fert. when moisture is your limiting factor 4 years out of 5. If you get that one good year, put on an extra few lbs for your bank.

I wouldn't mind someday building a toolbar for our self propelled sprayer to sidedress and put on a late application of N if the growing season had presented plenty of moisture.
