KiS Mineral Mix Soil Amendment Blend: Rock Dust, Phosphate and Calcium

• Gaia Green Glacial Rock Dust: A mineral product shaped by thousands of years of glacial action. It supplies calcium, iron, magnesium, potassium, trace elements and micronutrients, and helps improve soil structure, moisture holding and drainage.
• Calphos Soft Rock Phosphate: A slow-releasing phosphate containing 20% total phosphoric acid and 20% calcium. It helps feed soil microbes and balance soil pH.
• Pacific Pearl Oyster Shell Flour: 36% calcium and 92% calcium carbonate equivalent, from finely ground oyster shell. Faster acting than ag lime.
• Basalt Rock Dust: Supports soil microbial activity and humus formation, helps neutralize pH and adds phosphorus.
• K-Mag 0-0-22: A naturally occurring 3-in-1 source of potassium, magnesium and sulfur in the water-soluble sulfate form.

• 21-22% Potash (K₂O) (18.2% potassium): supports fruit quality, root health and sugar and starch formation.
• 10.5-10.8% Magnesium (Mg) (18% MgO): the central component of chlorophyll.
• 21-22% Sulfur (S) (67% sulfate, SO₄): helps build proteins and supports early root growth and seed production.

Mix 2 cups of KiS Mineral Mix into each cubic foot of soil mix.
