Why the change in attitude? As the leader in quality and purity of pelletized lime and gypsum we could no longer ignore our customers request for certification.

We learned and shared with our organic and biological customers and one main theme kept coming up. Take care of the soil and everything else works better.

Looking to increase quality, look to the soil. Want to reduce the amount of chemical fertilizers, herbicides and pesticides you apply, look to the soil.

High yielding high quality crops start with taking care of the soil. Taking care of the soil means applying only the finest ground highest quality lime and gypsum.

At Calcium Products we pride ourselves in being the nation’s expert in pelletizing finely ground minerals for easy application.
