Composition

Why Plants Need Calcium

Calcium is one of the most important nutrients required for healthy plant growth. It strengthens plant cell walls, improves nutrient movement, supports root development, and enhances the structural integrity of fruits and vegetables.

A deficiency of calcium can result in:

• Poor root growth
• Weak stems
• Flower drop
• Poor fruit setting
• Cracked fruits
• Reduced shelf life
• Soft fruits
• Low market quality

Cal-Xtra 40 supplies readily available calcium to overcome these problems.
