| FUNCTION IN PLANTS |
OCCURRENCE UNDER DIFFERENT SOIL CONDITIONS |
- Participates in the release of energy from energy-transferring molecules.
- Participates in breakdown of plant hormones.
- Involved in nitrogen uptake process which is impaired at deficiency.
- Essential in photosynthesis, there assisting Fe in energy transport.
|
- Plant-available under reduced conditions when soil is water saturated.
- Plant-available Mn increases with increasing pH.
- In particular high levels of pH reduce uptake of Mn.

| DEFICIENCY SYMPTOMS AND CONSEQUENCES |
PLANTS PRONE TO DEFICIENCY |
- Symptoms in broad leaf crops are yellow necrotic areas between the leaf veins, first visible on young leaves.
- Grayish green spots and stripes on basal leaf parts of grasses and grains.
- Results are reduced yield and poor harvest quality.
|
- Oat, wheat, barley, pea, cherry, citrus, soybean, sugar beet and potato.
