Understanding How thCa™ Works

Solutions that touch every part of your agronomic program!
Calcitic limestone combined with thCa™, an organic complexing agent, converts insoluble calcium compounds to soluble and available calcium. This allows for greater delivery of calcium to the exchange sites on the soil colloid. VERDE-CAL contains Aqua-Aid penetrant which synergizes with thCa, providing uniform nutrient movement into the entire soil profile.
• 500 pounds will yield results equivalent to 1 ton of typical lime
• Reduces hydrogen, sodium, and chlorine in the plant and soil
• Improves germination, stimulates root growth, and enhances microbial activity
• Increases essential nutrient absorption and translocation
• Improves soil structure (flocculation, water infiltration)
• Supplies optimum calcium levels to plant cells to strengthen the plant’s resistance to disease
• Balances the Ca/N ratio in the plant
• Quicker response at lower rates
• Requires 1/4 the rate of standard lime per application
