AG Lime (Calcium Carbonate) really can't be over applied and SLOWLY maxes out at a Ph of 8.4...Ag lime is nothing more than crushed limestone and dissolves slowly as acids react with it. Ag Lime can provide benefits for several years....A soil test will let you know the "tons per acre" needed to raise Ph in your soils.

Hydrated Lime (Calcium Hydroxide) almost instantly raises Ph over 12 depending on the concentration and is short lived in water.

most Farm Co-Ops have bulk ag lime and deliver it with spreader trucks...usually runs around $15/ton delivered and spread...just tell the driver to get as close to the water as possible and letter rip.
