Rocky Mountain BioAg® Premium Montmorillonite Calcium Bentonite: Essential Support for Optimal Soil Health

Achieving successful plant growth starts with healthy, balanced soil, and Rocky Mountain BioAg® Premium Montmorillonite Calcium Bentonite is the tool you need to enhance soil quality. Known for improving soil wettability, this premium, all-natural calcium bentonite blend delivers essential nutrients and supports the soil’s ability to retain water and nutrients effectively, creating an ideal environment for plant vitality.

Why Choose Premium Montmorillonite Calcium Bentonite?

Sourced from the finest deposits, our montmorillonite provides a potent blend of calcium, magnesium, and potassium, improving both soil structure and nutrient availability. By increasing the soil’s cation exchange capacity (CEC), it prevents nutrient leaching and ensures that plants can access the minerals they need to thrive.

Key Benefits:

  • Enhances Soil Wettability: Improves soil’s water-holding ability, ensuring plants receive consistent moisture.
  • Boosts CEC: Increases nutrient retention, so plants absorb more nutrients over time.
  • Prevents Nutrient Leaching: Protects valuable nutrients, reducing the need for frequent amendments.
  • All-Natural Nutrient Source: Supplies calcium, magnesium, and potassium to enrich soil structure.
  • Flexible Applications: Available in sizes from 3.75 lbs. to 2000 lbs., suitable for all scales of use.

Application Instructions and Rates:

  • Bulk Applications: Use 500–1000 lbs. per acre every other year, incorporating 2”–4” deep for optimal results.
  • Fertilizer/Compost Additive: Mix 2%–5% by weight into compost or fertilizer to boost efficiency.
  • Established Turf Grass: Apply 25 lbs. per 1,000 sq. ft. in spring as a top dressing.
  • Ornamentals & Raised Beds: Apply 1 lb. per 40 sq. ft. and work into soil 2”–4” before planting.
  • Transplants & Potting Soil: Use specified amounts per root ball size or potting soil volume for precise nutrient support.

Improve your soil’s structure, nutrient retention, and water capacity with Rocky Mountain BioAg® Premium Montmorillonite Calcium Bentonite—essential for sustainable, resilient plant growth.

I have a greenhouse that unfortunately does not get the ideal sunlight due to its location on the north side of my home. I have been using Rocky Mountain BioAg’s Quantum Growth Organic Total for over a year and have seen a dramatic increase in plant growth and vegetable yield compared to past years. Highly recommend the product.
