DESCRIPTION
WHO CAUSES IT?
Boron is an essential micronutrient for cell formation and elongation, fertilization, flower and fruit development, and sugar transport within the plant. Its deficiency is common in sandy, acidic, or low-organic-matter soils, and under drought conditions, as its mobility depends on water. Boron deficiency primarily affects actively growing tissues, causing deformities, flower abortion, and premature fruit drop.
SYMPTOMS
Boron deficiency first manifests in young shoots, flowers, and developing fruits due to their limited mobility within the plant.
Typical symptoms:
• Flower abortion and flower drop.
• Deformed, dry, or necrotic fruit.
• Dead or deformed terminal shoots.
• Small, curled, or chlorotic young leaves.
• Weak, brittle stems.
• Reduced root growth in young plants.
Boron deficiency develops rapidly in young tissues and reproductive organs. If left uncorrected, it compromises fruit and seed production, seriously affecting crop yield and quality.
Developmental stages:
• Early: Small, curled young leaves, shoots with limited growth.
• Intermediate stage: Flower and young fruit abortion, organ deformation.
• Advanced: Necrosis in fruits, death of terminal shoots.
• End: massive drop of flowers and fruits, significant reduction in the harvest.

Chemical treatments
• SOLUBLE BORON FERTILIZERS: Sodium borates or boric acid; rapid correction of deficiencies.
• ENCAPSULATED / CONTROLLED-RELEASE FERTILIZERS: Avoid toxicity and provide B gradually.
• ORGANIC FERTILIZERS + BORON: Compost enriched with microelements; gentle and sustained contributions.
• FERTILIZERS WITH AMINO ACIDS + BORON: Rapid foliar applications during flowering and fruit set.

To maintain adequate boron levels and ensure proper flower and fruit development, it is important to optimize its availability and absorption through fertilization and soil management.
• Apply boron fertilizers (borates) according to the crop type.
• Apply foliar boron applications during critical flowering and fruit set periods.
• Incorporate compost or organic matter containing boron.
• Maintain adequate irrigation to promote absorption.
• Avoid extremely acidic or sandy soils without amendments.
• Control weeds that compete for nutrients.
