Manganese deficiency made worse by
- Organic soils
- Sandy soils
- High pH
- Cold wet periods
- Fluffy soils
Manganese is important for
- Boosts growth
- Ensures good crop quality with high sugar and vitamin C contents
Symptoms
Young leaves show yellogreen mottling, caused by interveinal chlorosis. Leaf blades are enlarged, but not cupped inwards as usual.
Reasons
Manganese deficiency
Over-liming, the occurrence of very loose, highly aerated soils and also drought render Mn less available.
Crops grown in high organic matter, in peat soils or substrates also suffer from poor Mn availibility.
Symptoms
Young leaves show yellogreen mottling, caused by interveinal chlorosis.
Leaf blades are enlarged, but not cupped inwards, headforming is inhibited. Petioles are longer than usual, giving the plant a loose appearance.
