Magnesium is absorbed by the roots of the plant as magnesium ion (Mg2+). The magnesium ion plays an important role in the development chlorophyll, which gives the leaves of plants their healthy green colour. Also, magnesium is indispensable for the process in which amino acids are converted into proteins. With a good intake, the magnesium content in a plant can rise to 3%. Due to the natural origin, the nutrient content may vary.

Biota Iron is based on lignosulphonic acid and part of our liquid biological single fertilizer line. Due to the unique production process, the nutrients are 100% present in the solution and can therefore be taken up directly by the plant. The product is fully made from plant-based materials and certified for use in organic agri- and horticulture. The ingredients are partly sourced from agricultural waste. Due to the natural origin, the nutrient content may vary. Biota Iron is used for prevention and correction of iron chlorosis under all types of conditions, including calcareous and alkaline. You first notice 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.

Biota Molybdeen 4,1% is a concentrated single molybdenum fertiliser and part of our liquid organic single fertilizer line. Due to the unique production process, the nutrients are 100% present in the solution and can therefore be taken up directly by the plant. The product is fully made from plant-based materials and certified for use in organic agri- and horticulture. The ingredients are partly sourced from agricultural waste. Due to the natural origin, the nutrient content may vary. Biota Molybdeen 4,1% is essential for the growth of a plant. It enables the formation of various essential enzymes, which regulate the protein formation in the plant. Molybdenum also ensures the absorption of nitrogen from the atmosphere. The right proportion of molybdenum has a positive effect on the colour intensity. Too much molybdenum causes displacement of copper, which results in crops with yellow coloured leaves.

Biota Manga is a concentrated single manganese fertiliser, based on lignosulphonic acid and part of our liquid organic single fertilizer line. Due to the unique production process, the nutrients are 100% present in the solution and can therefore be taken up directly by the plant. The product is fully made from plant-based materials and certified for use in organic agri- and horticulture. The ingredients are partly sourced from agricultural waste. Due to the natural origin, the nutrient content may vary. Biota Manga improves the photosynthesis of the crops. It manages enzymes which are responsible for green leaves. A shortage of manganese in the soil causes a pale green discolouration and speckled sports on the plant. Use Biota Manganese preventative for optimal growth and curative when a manganese deficiency occurs in the crop. Manganese creates strong cellular walls. Biota Manganese therefore increases resistance against fungal diseases. The absorption of manganese is highly dependent on a correct pH value of the soil. Manganese has an antagonistic effect on iron.
