What is Bio-Cal®?
Bio-Cal is a highly reactive calcium-based soil amendment engineered to rapidly correct soil structure and unlock nutrients for increased forage and crop performance.
Bio-Cal is the go-to product for growers looking to increase their nutrient availability, offering unique sources of calcium that improves plant availability and uptake, reduces compaction, and boosts crop profitability.
Bio-Cal Decreased Spring Soil Compaction in Multi-Year No-Till Corn/Soy Trials – South Eastern MN

- Spring soil compaction was reduced 19% (44 PSI) with the application of Bio-Cal.
- Data was collected on multi-year Bio-Cal trials with EarthOptics soil penetrometer readings.
Product Characteristics
- Unlocks soil nutrients
- Bio-Cal delivers reactive calcium, which increases nutrient availabilty and balance throughout the soil profile.
- Each ton provides roughly 100-120lbs. of usable calcium, helping unlock tied-up potassium and other nutrients so crops can use them in year one.
- Breaks up compactions
- By loosening tight soil and improving structure, Bio-Cal reduces compaction in the critical seed and root zone, improving water infiltration, rooting depth, and stand consistency.
- Mitigates salt stress
- Bio-Cal helps push excess salts away from the root zone, reducing salt stress that can harm roots and limit growth, especially where manures or high fertilizer rates are used.
- Improves nutrient efficiency
- By helping correct imbalanced Ca:Mg rations and supporting better soil structure, Bio-Cal improves the movement and uptake of macro- and macronutrients, so more of what you apply ends up in the plant.
Loyal to your Soil Benefits
- Acting as a catalyst in soil fertility programs, Bio-Cal helps to mobilize nutrients, unlock soil potential, and promote healthier, stronger plants all season long.
