​​​Our Partnership with Calcean
We’re excited to partner with Calcean, a company rethinking how natural resources can be responsibly sourced and integrated into modern industries. Calcean’s work centers on renewable, biogenic calcium carbonate derived from oolitic aragonite sand formed naturally in The Bahamas, offering a more sustainable alternative to conventionally mined materials.
What Is Oolitic Aragonite?
Oolitic aragonite is a renewable, sustainably sourced calcium carbonate that forms naturally on the shallow banks of The Bahamas during precipitation events known as whitings. During these events, blooms of cyanobacteria capture atmospheric carbon, triggering a natural mineralization process that produces oolitic aragonite.
​
Unlike traditional ground calcium carbonate (GCC), which is mined and non-renewable, oolitic aragonite forms continuously through natural biological and geochemical processes.
Why Oolitic Aragonite?
Oolitic aragonite offers several advantages over standard mined GCC due to its unique morphology and surface characteristics, including:
-
Higher surface area
-
Strong negative zeta potential
-
High calcium bioavailability
These properties make it a highly effective and versatile input across agricultural and industrial applications.
Benefits
Oolitic aragonite is easy to handle and apply. Its low minus-200-mesh content minimizes dust, improving safety and spread consistency. It can be applied using standard lime spreaders, truck casters, or fertilizer buggies.
To support ongoing aerobic biological activity, the material is delivered at approximately 5% moisture content. It distributes evenly in both dry and wet conditions. Initial applications may be applied at higher rates to raise soil pH and establish a stronger buffering capacity.
