I am in need of a field dirt mixture of about 60% clay and 40% sand or something similar (some say 50% clay 25% sand and 25 % silt). I have had a few contacts given to me but none came through. I live in western Kentucky and need a supplier for this dirt and am willing to go 300 or 400 miles to get it. Is there anyone out there that tell me of a supplier or someone to contact to get this? Also, which mixture would give me the best results for a youth baseball infield?
