Quality First

As a manufacturer of fertilizers used around the globe the foremost responsibility of our lab is to ensure that our products exceed the highest standards in quality. The JR Peters Laboratory is the scientific center for Jack’s Fertilizers. From start to finish we watch over our own processes to bring our customers the finest water soluble fertilizer and we can prove it! We’ve put a raw material qualification process along with our batch and lot tracking system in place so that our final products deliver everything they’re supposed to and nothing that they aren’t.
