Yes, Biomin Calcium is OMRI Listed, meaning it meets the standards for use in organic production. It is derived from natural sources like calcium carbonate and hydrolyzed vegetable protein.
You can use either method depending on your needs. Foliar application allows for rapid uptake through the leaves to correct deficiencies quickly, while soil drenching provides a steady supply of nutrients to the root zone.
No, the nitrogen in this product is provided via amino acid shells that release slowly. This formulation is specifically designed to improve fruit firmness and quality without triggering the rapid, unwanted vegetative growth often associated with high-nitrogen fertilizers.
The encapsulation process protects the calcium from reacting with other elements in the soil, which often renders standard calcium fertilizers inactive. This ensures the calcium remains bioavailable and ready for the plant to absorb immediately.
