| FUNCTION IN PLANTS |
OCCURRENCE UNDER DIFFERENT SOIL CONDITIONS |
- Major function is in energy transport system.
- An essential constituent of chlorophyll.
- Activates an enzyme which catalyses incorporation of CO2 in photosynthesis.
|
- Deficiency occurs in leached humus soils and sandy soils given lime, especially if soil is rich in K.
- Plant uptake is most favored in neutral soils.
|
| DEFICIENCY SYMPTOMS AND CONSEQUENCES |
PLANTS PRONE TO DEFICIENCY |
- Old leaves become yellow between the veins. In extreme cases leaves become necrotic and die off.
- In cereals leaves show chlorotic spots along the leaves.
|
- Sugar beet, potato, hops, vine, nut and glasshouse crops.
