These high-quality raspberries were grown in Mexico, where applications of OMEX CalMax helped maintain fruit size and firmness throughout development.
CalMax supplies calcium, an essential nutrient for strong cell walls and healthy fruit growth. In raspberry production, maintaining adequate calcium levels is important for achieving firm fruit with good shelf life, particularly for crops destined for export markets.
Benefits of CalMax include:
- Correcting and preventing calcium-related disorders.
- Improving fruit firmness and storage life.
- Supporting fruit quality and marketable yield.
Why Calcium Matters in Raspberry Production
Calcium plays an important role in the structure of plant cell walls, helping fruit maintain firmness as it develops and ripens. However, as raspberries approach maturity, calcium levels within the fruit can decline, increasing the risk of softer fruit and reduced post-harvest quality.
Applying CalMax during key stages of crop development helps maintain calcium availability when demand is high, supporting fruit firmness, quality and overall marketability.
