Manganese Deficiency

Nutritional disorder - Manganese (Mn) deficiency

A nutritional deficiency affecting chlorophyll production, nitrogen assimilation, and carbohydrate metabolism in trees. Manganese works with iron in chlorophyll manufacture and is essential for normal growth and development.

Peak Season: Symptom appearance: During active growing seasonMost visible: On new growth and young leavesPeak expression: Mid-growing season when demand is highestRecovery potential: With proper treatment and favorable conditions

Manganese deficiency symptoms in leaves

Identification & Symptoms

What to Look For

Chlorosis with wide green bands along leaf veins (broadleaf trees)
Necrotic interveinal spots on leaves
Leaves becoming limp and wilted
Stunted shoot growth throughout the tree
Smaller than normal fruits and seeds
New growth being stunted and chlorotic (conifers)
Older needles and lower crown remaining green (conifers)

Potential Damage

Reduced photosynthetic capacity from chlorosis
Stunted growth and poor vigor
Disrupted carbohydrate metabolism
Impaired nitrogen assimilation and protein synthesis
Reduced fruit and seed production
Increased susceptibility to other stress factors

Lifecycle

Nutritional deficiency disorder caused by insufficient manganese availability in soil or poor uptake by tree roots. Can be influenced by soil pH, drainage, and competing elements.

Professional Treatment Approach

1

Soil testing to confirm manganese deficiency

2

Mauget nutritional supplementation programs to correct deficiency

3

Improve soil drainage to enhance nutrient uptake

4

Adjust soil pH if necessary to improve manganese availability

5

Address competing nutrient imbalances
