$ 7.00 $ 8.00

  • Product Description

      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.
