Biota Calcium

Biota Calcium is unique because it is highly concentrated and suitable for use in organic production. It prevents and corrects calcium deficiencies in a wide range of crops. Due to the unique production process, the nutrients are 100% present in solution and can therefore be taken up directly by the plant through foliar application as well as irrigation. The product is fully made from plant-based materials and approved for use in organic agri- and horticulture. The ingredients are partly sourced from agricultural residual streams.
