Molybdenum deficiency made worse by
- Acid soils
- Low pH
- Low levels of soil organic matter
Molybdenum is important for
- Efficient use of nitrate and P metabolism
Symptoms
Bright yellow spots develop near leaf margins and between leaf veins. These areas can turn necrotic.
Leaves become distorted and narrow, rolling downwards such that margins meet underneath the main vein.
Older leaves are affected first.
Reasons
Molybdenum deficiency
Sorry there is no picture available at the moment.
Mo requirements are very low and most soils have sufficient reserves to meet crop demands.
As Mo availibility increases with the soil pH, deficiencies may be seen on strongly acidic soils.
