Never use liquid lime. You will pay to have tons of water sprayed, and get very little actual lime. Do not believe claims that "it acts faster because it is a liquid, so you need less."

Pelletized lime is fine if you have a small plot, but it is expensive relative to powdered lime. It is ground finer and does react faster, but you still need the same tonnage/acre.

MI is blessed with a lot of limestone & dolomite (the rock they crush to make lime). You should be able to find a decent supplier nearby, especially if you are in ag country. Haystack gave some good advice on spreading.

Get a soil test (MSU has a soil test lab; always use an in-state or bordering state lab), and apply lime to the reccomendation from the lab for the most sensitive crop you are planning to grow. For example, a soybean-corn-alfalfa rotation should be limed to a pH of about 7.0 for the most sensitve crop (alfalfa). Another option would be to pick your crops based on the pH of the soil. Liming should not be a major problem for you. Best of luck with the plots.
