Fast-Acting Liquid Calcium
Chelated Liquid Calcium Technology
AgriCal® is a highly soluble liquid calcium supplement designed to deliver immediately available calcium to crops and soil, correcting deficiencies more efficiently than traditional lime. While calcium is one of the most essential nutrients for plant structure, root health, and nutrient transport, it's often overlooked or misunderstood due to an over-reliance on pH as the sole indicator of soil health. Unlike agricultural lime, which is slow to dissolve and may take years to become plant-available, AgriCal® provides a rapid-release form of calcium that's ready for immediate uptake. This allows growers to respond quickly to calcium deficiencies, even in soils that already contain undissolved limestone or show a neutral pH. AgriCal® supports improved cell wall strength, root development, nutrient uptake, and stress resistance. It can be applied directly to soil, through fertigation systems, or as a foliar spray to ensure crops receive the calcium they need at critical stages of growth.
Immediate Availability
Highly soluble liquid calcium provides immediately available nutrients, correcting deficiencies faster than traditional lime.
Improved Nutrient Uptake
Enhances uptake of ammonium, potassium, and phosphorus while making nitrogen use more efficient.
Rapid Response
Works immediately without waiting years for lime to break down, perfect for addressing urgent calcium deficiencies.
Enhanced Cell Structure
Strengthens cell walls, improves root development, and supports overall plant structure and health.
Stress Resistance
Increases plant tolerance to environmental stress and helps offset toxic effects of aluminum in acidic soils.
Versatile Application
Apply directly to soil, through fertigation systems, or as a foliar spray for maximum flexibility.
How AgriCal® Works: Unlocks Tied-Up Calcium
AgriCal® helps activate and break down previously applied calcium sources in the soil, converting them into plant-available forms. This allows crops to access existing calcium more efficiently, improving uptake without relying solely on new calcium applications.

Calcium Recommendations Based on Soil Test
Calcium Recommendations Based on Soil Testing
AgriCal® application rates are determined using soil test data, just like any other essential nutrient. Rather than applying a fixed rate across all fields and crops, we base calcium recommendations on current soil conditions to ensure accuracy and efficiency. We use base saturation as the most reliable way to evaluate calcium levels and balance in the soil.
We strongly recommend using up-to-date soil tests and speaking to a consultant before making any calcium applications. When soil test data is not available, a general application rate of 2.5–3.0 gallons per acre may be used as a practical guideline.

Mixing Warning: Do NOT mix with 2,4-D amine. Always jar test compatibility and follow the product label before tank mixing.
Application Guidelines & Best Practices
Application Methods
- Soil: 2-10 gallons per acre
- Foliar: 1-3 gallons per acre
- Liquid Nitrogen Solutions: AgriCal® should be used
- at 2-5 gallons per acre with all Liquid N applications.
Important
- To avoid the formation of insoluble precipitates, do NOT mix with materials containing Phosphates or Sulfates. Do NOT mix with any Round-Up® type herbicides (Glyphosate based).
Research-Backed Calcium Performance
AgriCal® delivers proven results backed by university research and real-world grower experience. Studies conducted by Texas A&M University show that applying soluble calcium with urea can increase yields by 14–50%. Unlike traditional lime that takes years to dissolve, AgriCal's chelated calcium provides immediate nutrient availability, addressing true calcium deficiency regardless of soil pH. Real science, immediate results, maximum efficiency.
Research-proven yield increases when calcium is applied with nitrogen
Apply 1/2 to 1 pound of liquid calcium per pound of urea for best results
Improves uptake of ammonium, potassium, and phosphorus
Soil, foliar, or fertigation application for maximum convenience
