if you have a big or small pickup, you can go to the quarry and get 1 or .5 tons of lime at a time. around here in kansas there is a quarry about every 30 miles. lime is $6/ton.

to spread it, have some drive around your plot and you sit in back and blow it out with a gas powered leaf blower. it took me about 15 minutes to spread .5 a ton with this method. it's easier than you think, especially if you're the one driving the truck.
