This role of manganese in plants is extremely crucial. Location in plant Zinc deficiency. Manganese is an immobile nutrient and, therefore, deficiency symptoms show up on younger leaves first. Plants do not need much manganese for health or growth, but this micronutrient is essential. Prior to use, it may help to thoroughly water the area or plants so that the manganese can be absorbed more easily. Symptoms show yellowing between the veins, which remain dark green. It is essential for calcium absorption, normal brain and nerve function, digestive enzyme production, immune health, and blood sugar regulation. Manganese deficiency looks similar to magnesium (Mg) deficiency but Mg deficiency is often much more pronounced in the older leaves on the plant.
