what you reccommend then if not clover? i gotta get dirt for aph test as soon as all this snow melts.......we got over a foot of snow in the past few days. im planting 2 plots all easily accessible. i have a tractor with bushhog, scraper blade, and auger. i have a rototiller but i imagine its a lot easier with a disk........i could probably get my hands on a disk and a roller
