I put out 12 ton (3 buggies at 4 ton each) from the Hamilton Co-op two weeks ago, going to pull a soil test this fall and see how much it helped. Pretty good deal from them buy the lime and they let you use their pull behind buggy, 4 tons is a a lot with a 1500 truck but it worked out ok I was able to get to most of my plots without hooking it to the tractor.
