Such a common problem as magnesium deficiency in plants usually results in the deterioration of growth and production processes and slows down the synthesis of nitrogen-containing compounds. As a result, the production of quality chlorophyll content and disease resistance decrease. Magnesium is absorbed only in the form of Mg2+ ions. It mainly accumulates in the organs and seeds of young plants. It is more mobile and can be reused by the plant. From the old leaves, it enters the young ones, and after flowering, flows from the leaves to the seeds, concentrating there. The lack of magnesium affects the yield of seeds, roots, and tubers more sharply than straw or chaff.
Magnesium Deficiency in Plants
Signs of damage
- manifests itself in the form of a kind of interveinal chlorosis;
- the leaves become spotted (marbling), pale, and yellowish.
- begins with the edges of the lower leaves;
- later, brown spots appear between the veins on the leaf, while the veins remain green;
- with a strong deficiency of magnesium, the leaves die and fall, and the plant may not bear fruit;
- most often appear in the second half of the vegetation period.
How to prevent
To prevent magnesium deficiency, use a liquid fertilizer containing a high magnesium concentration for foliar-feeding crops. Magnesium lime is also a very effective source of magnesium in the soil. The magnesium content, in this case, depends on the manufacturer and the origin of the particular fertilizer. For optimal soil fertility, systematically add small maintenance doses of fertilizer. In addition to magnesium lime, there is another magnesium-rich fertilizer, kieserite.
Heal
When clear signs of magnesium deficiency are clearly visible, you can try to save your plants by feeding the leaves. However, in the future, it is necessary to bring the content of the substance in the soil to the optimum level. In addition, using an aqueous solution of magnesium sulfate increases the amount of this element in plants without affecting the amount of magnesium in the soil.
