Nutrition & Biology
A multi-mineral, microbe-rich soil amendment designed to support healthier soil biology, stronger roots, and resilient plant growth.
Solutions for every grower.
Soil doesn't need more chemicals. It needs life.
Healthy plants begin with healthy soil.
Decades of intensive farming, repeated synthetic fertilizer use, and natural mineral depletion gradually reduce the biological activity that keeps soil productive. As beneficial microorganisms decline and essential minerals become less available, soils lose their ability to efficiently cycle nutrients, support strong root systems, and retain long-term fertility.
Spanish River Carbonatite (SRC) works differently.
Rather than acting as a single-purpose input, SRC contributes a naturally occurring combination of calcium, phosphorus, potassium, magnesium, silica, and trace minerals while supporting the biological processes that drive healthier soils.
Six reasons growers keep coming back.
More than lime.
Traditional agricultural lime helps correct soil acidity. SRC helps build healthier soil.
- Raises soil pH
- Primarily calcium
- Single-purpose amendment
- Limited biological contribution
- No phosphorus or potassium contribution
- Primarily chemical correction
- Raises soil pH
- Calcium + Phosphorus, Potassium, Magnesium & more
- Multi-functional soil amendment
- Supports microbial activity through 12+ naturally occurring microbes
- Naturally contributes P, K, Mg and trace minerals
- Supports biological & mineral restoration

Science that starts underground.
Healthy soil is a living ecosystem — not simply a growing medium. SRC supports the natural relationships between minerals, microorganisms, roots, and plants.
Instead of forcing plant growth through repeated chemical inputs, SRC helps restore the biological processes that naturally improve soil function.
Research in action.
Scientific studies consistently demonstrate measurable improvements in soil quality, root development, microbial activity, and plant growth following SRC application.
