At TradeMark Nitrogen, we’re proud to offer CAL-12^®, a premium liquid calcium fertilizer designed to meet the nutrient demands of modern agriculture. With 12% calcium in a fully soluble, plant-available form, CAL-12^® provides superior performance for crops across the Southeastern United States.

Why Calcium Matters

Calcium is essential for plant structure, root development, and nutrient uptake. It plays a critical role in cell wall formation, helping plants stand up to environmental stress and disease pressure. Deficiencies in calcium can lead to weak cell walls, blossom end rot, poor root systems, and lower yields—especially in high-value fruits, vegetables, peanuts, and field crops common in the Southeast.

What Makes CAL-12^® Different

CAL-12^® delivers calcium in a clear, low-salt liquid that’s ideal for fertigation, side-dress, and foliar applications. Its clean formulation ensures compatibility with most other fertilizers, making it easy to incorporate into existing nutrient programs. Unlike dry calcium sources, CAL-12^® provides rapid uptake and uniform application without clogging or settling.

Tailored for the Southeast

Sandy soils, acidic pH, and high rainfall in the Southeast often lead to calcium leaching and limited nutrient availability. CAL-12^® is formulated specifically to address these regional challenges, helping growers maintain calcium levels throughout the season—from planting to harvest.

Benefits at a Glance:

• 12% highly soluble calcium
• Low salt index for safe application
• Compatible with liquid N, P, and micronutrients
• Excellent tank-mix partner

Whether you're managing row crops, specialty produce, or turf, CAL-12^® delivers the calcium your crops need—when and where they need it.
