Organic Mandarin (Citrus Reticulata) Cultivation Program with Ecoganic Products

Introduction: Organic Mandarin Production in Ecological Systems

The mandarin (Citrus reticulata) is a citrus fruit of high commercial value widely cultivated in regions such as Spain, Peru, Argentina, Mexico, and Morocco. Its organic production presents competitive advantages in demanding international markets, where residue-free products with ecological certification and superior post-harvest quality are valued.

However, growing mandarins under ecological management involves facing specific agronomic challenges:

• High and well-balanced nutritional demands.
• Susceptibility to soil and aerial diseases (Phytophthora, Alternaria, etc.).
• Sensitivity to calcium and microelement deficiency.
• Need for an active root system and well-structured soils.
• Typical pests such as mites, thrips, aphids, and leaf miners.

This technical program is based on the cross-validation of the Ecoganic catalog, the technical data sheets, the documents “CULTIVATION PROGRAMS”, “Ecoganic Trials (1).docx”, and updated references from the ecoganic.eu portal, guaranteeing an efficient, sustainable strategy compatible with the EU 848/2018 and USDA NOP certification standards.
