Molybdenum deficiency-Soya bean

症状
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.

原因
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.

症状
Several leaves, different in age, show a light green to yellow chlorosis, spreading irregularly over the leaf blade.

症状
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.
