Saw an article about them in our local "Cattle Mag", a companion to the AgMag. Seems they are critical to getting organic material back into the soil.
Need a few more up where I was hunting the other day, look like some floppies up there were more than a few years old.
I'll try the turnip thing in one of my garden beds, maybe some fall as a cover crop and let them rot over the winter.
Thanks for the lesson Jim.
