RE: Lime
6.75 a ton around here, you haul you spread. there's a quarry about every 45 miles. 2 tons per acre should be about the most you'd need, you need a soil test first. 3.5 acres x 2 tons/acre x 6.75/ton = not too much money. you need to do it soon, as it takes up to 6 months for the lime to start working.
