The funny thing is, while that report came from UF, I actually can't recall seeing an earthworm in South Florida sand. In all the clearing, pond digging and trenching I've done in Okeechobee, not one worm. I was actually trying to find a reason when I came across the UF report. Based on the recomended temperatures in the report, I suspect it's just too hot for them. I though maybe they'd be deeper, but we dug the pond to about 16' in the Fall, and I didn't see any. I didn't even see any when I flipped my tractor into a 10' deep hole...and I had to crawl and scratch my way up the bank /forums/images/graemlins/crazy.gif
