The soil amendment your garden's been missing.
Unlike conventional fertilizers that deliver a quick nutrient boost and then fizzle out, Spanish River Carbonatite (SRC) works with your soil — re-populating it with naturally occurring beneficial microbes and nutrients to support long-term soil health.
Supports every part of a healthy garden
Healthy plants are built from the soil up. SRC supports multiple aspects of soil and plant health through its naturally balanced mineral composition and beneficial microbial activity.
Perfect for what you want to grow
Whether you're planting a single houseplant or transforming your entire backyard, SRC integrates easily into almost any gardening routine.
Simple to use, anywhere you grow
Because SRC functions as a soil amendment rather than a conventional fertilizer, it's designed to become part of your soil — not dissolve away after watering.
Amounts shown are general guidelines — always refer to the product packaging for exact application rates.
Why SRC is unique
Garden centres are full of fertilizers and soil products that promise fast results. SRC takes a different approach.
Proven in research. Visible in your garden.
SRC has been studied through independent research and field trials for nearly 30 years, across multiple countries and growing environments.
Give your soil the strength it needs
to support your garden.
Healthy gardens begin long before the first flower blooms or the first tomato ripens — they begin with living soil.
Build stronger roots. Support healthier plants. Grow with confidence.
