Lime cost here is $60 per ton delivered and spread. However, I did find another source that would deliver a minimum of 25 ton for $39. Just have to find a way to spread it.
That is high. I live just west of Nashville and can buy lime for $11/ton and get it spread for $12/acre. $23/acre spread with a 10 ton minimum.
We can get a full dual tandem dump truck load, about 22 tons delivered for $300 and rent a spreader from CO-OP that holds 7 tons per load for $125/day. If you have enough tractor and the time it is the cheapest way I have found.
