Soybean - Chlorosis
Symptoms
Mo deficiency symptoms are similar to N deficiency: Leaves are pale green to yellow and twisted. At progressing deficiency, the leaf margins, midribs and interveinal areas become necrotic.
Reasons
Molybdenum deficiency
Molybdenum deficiency occurs in highly acidic soils that are strongly weathered and leached and in soils where the element is in an unusable form.
Mo deficiency causes considerable yield losses.
Soybean - Chlorosis
Symptoms
Several leaves, different in age, show a light green to yellow chlorosis, spreading irregularly over the leaf blade.
Reasons
Molybdenum deficiency
Molybdenum deficiency occurs in highly acidic soils that are strongly weathered and leached and in soils where the element is in an unusable form.
Mo deficiency causes considerable yield losses.
Soybean - Chlorosis
Symptoms
Several leaves of different age show a light green to yellow chlorosis, spreading irregularly over the leaf blade.
Reasons
Molybdenum deficiency
Molybdenum deficiency occurs in highly acidic soils that are strongly weathered and leached and in soils where the element is in an unusable form.
Mo deficiency causes considerable yield losses.
Soybean - Chlorosis
Symptoms
Several leaves, different in age, show a light green to yellow chlorosis, spreading irregularly over the leaf blade. The bottom leaves additionally develop marginal necrosis. Small brown spots appear within the chlorotic zones. Some of them enlarge and become whitish, scorched, seamed by a fine dark line.

Soybean - Chlorosis
Symptoms
Younger leaves show a slight, rather even chlorosis.
Reasons
Molybdenum deficiency
Molybdenum deficiency occurs in highly acidic soils that are strongly weathered and leached and in soils where the element is in an unusable form.
Mo deficiency causes considerable yield losses.
Molybdenum deficiency made worse by
- Acid soils
- Low pH
- Low levels of soil organic matter
Molybdenum is important for
- Increased metabolism of phosphorus and iron
- Increased nitrogen metabolism
- Improved chlorophyll formulation
