Why Calcium Matters
Calcium plays a critical role in cell wall strength, root development, nutrient movement, and overall plant health. Maintaining adequate calcium availability helps support healthy growth while enhancing soil structure and rootzone conditions for improved water movement and nutrient uptake.
- Supplies a readily available source of calcium
- Flushes excess sodium from the root zone
- Improves soil structure and aggregation
- Enhances water infiltration and drainage
- Reduces soil compaction and surface crusting
- Improves fertilizer and nutrient efficiency
- Supports stronger root development
- Helps maintain a healthier, more productive rootzone
