How much ECCE lime should I use per acre?

Most agricultural lime sources range from 65 – 85 % ECCE. So, if your soil test called for one ton of 100% ECCE lime you would need to apply 1.33 tons per acre of a 75% ECCE lime. If a pelletized lime source were 90% ECCE it would take 1.11 tons per acre of this form to do the same job. This is a far cry from the, “it only takes a ¼ of the amount of pelletized lime versus ag lime” statement I have heard more than once. So although there are some instances where a little less pelletized lime is needed than ag lime, it’s a pretty negligible amount especially considering most people spread it in large quantities and it isn’t being figured to the 50-pound bag quantities like you would with NPK fertilizer.
