Biota Iron

Biota Iron is an Iron micronutrient complexed with lignosulphonic acid and part of our liquid fertiliser line. Due to the unique production process, the nutrients are 100% present in solution and are therefore directly available to the plant. Biota Iron is registered as input for organic agri- and horticulture.

Iron (Fe) is used for prevention and correction of iron chlorosis under all types of conditions, including calcareous and alkaline. You first see iron deficiency in the top of the plant. The leaves turn yellow, while the veins remain green. This is because iron is an immobile element. This means that once it is fixed, iron can no longer be distributed further in the plant. Eventually the older leaves and smaller veins in the leaves also turn yellow. The plant growth slowly stops. Use Biota Iron to prevent and correct these effects.
