Kinda like a preemergent only with nutrients instead of pesticides. ISU research also proves this. Lawns recover more quickly & stronger when they are fertilized during summer months.
That is one study I would like to analyze to see where the line is drawn between poor fertility needing fresh N apps and N burning...
The Late Spring app is the Summer app... once the temps cool around mid Aug. I'll be putting down the second round of fertilizer...

Do you have that ISU Research???
Now that I know that clay's texture(platelets) has nothing to do with water infiltration, percolation, or drainage
,,, I wonder what does...

Good point. Last year's drought = not all nitrogen was used up in corn, lawns, etc. Some folks water, but most don't. Hit & miss. Mother Nature will dictate. ISU experimented with as much as 10 lbs per K of actual N last year >> results were awesome.

We plan to attend their annual turfgrass field day on August 1, 2013.
