I would look at running as much AMS you can handle as well as Oats in the spring before the crop. Oats are very acidic and help reduce ph an...

Depends entirely on purity but $2-5

It varies some field to field but 25-30 gallons per acre per depending on acid purity. Per point of soil ph. I.E. 30 gallons should take you...
