Magnesium deficiency results in yellowing between the leaf veins, sometimes with reddish brown tints and early leaf fall. Not so stunted as major nutrient deficiencies. Older leaves turn yellow at edge, interveinal chlorosis causes green arrowhead shapes or marbling in the centre of the leaf (speckling in cereals). Necrotic tissue develops across the leaves and at the margins. The plant moves its magnesium to growing tissues, so deficiency always appears first in older leaves. This eventually leads to a shedding of leaves, but the plant is able to flower. Magnesium deficiency is common in tomato, apple, grape, raspberry and rose plants.
Plantations: 150 - 200 g per tree per annum.
Magnesium deficiency occurs in areas with high rainfall or wet regions, especially in light and acidic soils.
Benefits: Magnesium is the central atom of chlorophyll. Magnesium is necessary to achieve high concentrations of starch in potatoes, sugar beet and fats in oil seeds.
