Deficiencia de Magnesio
WHO CAUSES IT?
Magnesium is an essential secondary macronutrient and the central nucleus of chlorophyll, so its deficiency directly affects photosynthesis and growth. It is also involved in the activation of numerous enzymes and in the synthesis of carbohydrates and proteins. Deficiency usually occurs in acidic, sandy soils, or soils with excess calcium, potassium, or aluminum, which hinder its absorption. Since magnesium is mobile in the plant, symptoms first appear on older leaves.

SYMPTOMS
Magnesium deficiency causes interveinal chlorosis, beginning in older leaves and progressing to newer leaves if not corrected.
Typical symptoms:
• Yellowing between the veins of older leaves (interveinal chlorosis).
• Leaf margins remain green while the center turns yellow.
• Small or wilted leaves.
• Loss of vigor and slow plant growth.
• In severe cases, leaves show necrotic spots and premature leaf drop.
• Decreased fruit and seed production.
Magnesium deficiency progresses gradually and affects the plant's photosynthetic capacity and overall metabolism, compromising yield and harvest quality.
Developmental stages:
• Initial: interveinal chlorosis in older leaves, while the veins remain green.
• Intermediate stage: more intense chlorosis and the appearance of necrotic spots.
• Advanced: leaves with dead tissue and premature leaf drop.
• Final: growth stopped, small or deformed fruits and loss of yield.
