Spanish River Organic Soil Amendment, 2 Pound Bag

Spanish River Carbonatite is a volcanic carbonatite rock found in the Sudbury region in Northern Ontario, Canada formed over 2.8 billion years ago. It is an entirely natural, organically-approved, mineral soil amendment and mineral fertilizer, Spanish River Carbonatite contains an extensive suite of trace minerals. Many of the minerals are critical catalysts in mineral/microbial/plant interactions and explain in part SRC’s excellent response over a vast and complex array of different soil types and growing conditions.

SRC’s mineral composition is among the reasons that it is an agricultural problem solver. SRC is a combination of minerals such as calcium (60%), phosphorous (5%), potassium (2%), iron (4%) in association with magnesium and most of the micronutrients, trace elements and rare earths that are essential for optimal soil balance and healthy plant growth.

• Superior for organic gardening
• most extensive suite of trace minerals of any organic or chemical fertilizer we have found
• Organic chemistry, mineral/nutrient content
• (highest brix), accelerated germination
• Improved and increased root mass and root depth/extension
• 1 lb covers a 4’ x 5’ garden

How To Apply 

• Lightly sprinkle on selected garden area at a rate of 1lb per 21-25 square feet (about a 5x5-foot square) of garden space. Gently rake or till into surface.
• Sprinkle lightly into seed furrows or seed drill holes after seeding and before covering with soil.
• Sprinkle into planting holes for transplants.
• Add a tablespoon or two per gallon of planting mix for planters and pots.

Caution: Avoid breathing rock dust.
