I have certainly had success using corn to fertilize bent grass greens. THe water used to run off the greens like water flowing down a driveway, now the ground absorbs it like a sponge. Seems to me that would help keep the ground a little cooler.
The greens have been just barely staying green for the last three seasons, until this year when i applied corn they are DEEP green and thickening. That is a direct result of the corn. The greens have had spray weed and feed, and granular fertilizer the last 3 seasons and showed little or no improvement. Not every green is that way , but they all have improved signinficantly. If we ever get a decent rain around here , i expect all the greens will finally look like greens.
time will tell...
