Micronized Soft Rock Phosphate 0-9-0 (Cal-Phos)

High Phosphorus • Strong Roots • Enhanced Bloom Support

Our Micronized Soft Rock Phosphate, also known as Cal-Phos or Colloidal Phosphate, is derived from the fossilized remains of ancient organic life. Mined and processed in Canada, this natural, non-metallic mineral is rich in phosphorus, calcium, and trace minerals essential for strong root systems, vibrant blooms, and long-term soil fertility.

Key Benefits

🌱 Boosts Germination & Root Growth
Provides essential phosphorus and calcium to support early plant development and stronger root systems.

💧 Improves Nutrient Movement
Helps translocate vital minerals into plant tissues, promoting healthier, more resilient growth.

⚡ Highly Refined & Water-Soluble
Processed to a fine particle size under 10 microns for faster availability to plants.

💦 Ideal for Foliar & Soil Applications
Can be suspended in water for foliar sprays or applied directly to soil for quicker nutrient uptake.

🌸 Supports Bloom & Fruit Development
Acts as a natural bloom booster, increasing flower and fruit production without harsh chemical inputs.
