Magnesium deficiency-Soybean

Symptoms
Mg deficiency symptoms are light green to yellow chloroses of interveinal tissues. Leaf margins are bent down. The older, lower leaves are affected first.

Reasons
Magnesium deficiency. Magnesium deficiency is most prevalent in deep, sandy, acidic soil.

Soybean - Chlorosis

Symptoms
Mg deficiency symptoms are in the beginning light green to yellow chlorosis of interveinal tissues. The leaf base is concerned at last. Whitish to light brown necrotic blotches occur on the interveinal, marginal areas. Leaf edges show a whitish, bleached tint.

Magnesium deficiency made worse by

Sandy soils
Acidic soils
Potassium rich soils
Soils receiving high potash applications
Cold wet periods

Magnesium is important for

Complete chlorophyll molecules
Increased phosphate and nitrogen metabolism
Improved protein synthesis
More efficiant water uptake by the plant
