- with a strong deficiency of magnesium, the leaves die and fall, and the plant may not bear fruit;

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.
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.
