Refined for greater value
We subject Fertibor to rigid quality standards from extraction to refinement to shipping.
Composition: Highly pure, calcium free tincal ore from a unique deposit in California is what we use to produce Fertibor.
Refinement: Our ore is fully refined through a process that keeps impurities at a controlled, minimal level. Other products follow different or no refinement process, leaving higher heavy metals content such as arsenic.
