We’re super excited about this connection! Calcean is changing the way we look at natural resources and their incorporation into familiar products and industries. Their focus is on utilizing renewable, biogenic calcium carbonate derived from oolitic aragonite sand originating in The Bahamas.

​

What is ‘Ooltic Aragonite?

Oolitic aragonite is a renewable and sustainably sourced resource. It naturally forms on the banks of The Bahamas during natural precipitation events called ‘whitings.’ During these events, blooms of cyanobacteria sequester carbon from the atmosphere and a mineralization process occurs, forming oolitic aragonite [learn more about this process here.]

​

Oolitic aragonite is a versatile renewable resource that provides a number of benefits overs standard mined ground calcium carbonate (GCC). GCC is not a renewable resource and has a different morphological structure than oolitic aragonite. Oolitic aragonite’s unique structure affords it many benefits such as higher surface area, high negative zeta potential, and high calcium bioavailability.

Benefits

​

There are big benefits in the ease of spreading, in the fact that no dust is created due to the low minus 200 mesh material. The application of Aragonite is with large lime spreaders, truck casters or fertilizer buggies. To encourage the continual reproduction of the Aerobic bacteria, it is delivered with an approximate 5% moisture content. Distributes extremely well both dry and wet. Initial first application may be at higher rates to raise pH and to create a stronger buffer. 

Application rates vary. Recommended for maintenance at:

• 400 pounds per acre for grasses and small grain

• 450 pounds per acre for soybeans

• 750 pounds per acre for corn

• 500 pounds per acre for cotton
• 400 pounds per acre for peanuts

Fertilizer Enhancer

Oolitic aragonite is a highly pure, renewable and biogenic mineral, which is ideally suited to enhance fertilizer performance. Containing approximately 40% calcium and able to dissolve quickly, aragonite is a practical and efficient pH buffer. Further, aragonite has an innate ability to absorb nutrients deliverable into fertilizers, efficiently increasing their availability. This delivery mechanism is made possible because of a negative zeta potential in combination with a large surface area of the aragonite crystal. Aragonite also acts to neutralize volatilization of ammonia by reducing the hydrolysis of urea by delivering free calcium ions within fertilizers, thereby stabilizing the ammonia.

Turf Grass Amendments & Potting Soil

Oolitic aragonite is a highly pure source of calcium that acts as a pH control for turf grass amendments and potting soil and is an essential part of a healthy micro-nutrient formulation. Plentiful calcium increases tolerance to stressful conditions such as drought and close mowing. Oolitic aragonite is an exceptionally pure mineral, which is typically over 40% calcium and contains few impurities compared to conventional limestone sources. Aragonite has a unique morphology, which efficiently dissolves and delivers calcium to the soil. In a common soil where pH is 6, 65% of aragonite will be in the dissolved form. That far outperforms calcite at 10%, anhydrous gypsum at 28% and hydrated gypsum at 5%. In conjunction with its excellent delivery capabilities, aragonite acts a buffering agent with a pH above 8.2, an ideal combination for the cultivation of turf grass and potting soil.

OceanCal® powder is very pure, ground, Oolitic aragonite sand (calcuim carbonate) it’s unique crystalline structure, high purity and consistency offer economic and performance benefits.

SandyCal® sand is raw, naturally renewable oolitic aragonite sand that is 94-98% pure calcium carbonate.for the aragonite user, making it a superior source of calcium carbonate. SandyCal has been identified as a valuable component to beach restoration, phosphate mitigation, NOx removal, aquarium substrates and many agricultural uses. The grains are OOLITIC (egg-shaped) and smooth. It is tasteless, odorless, dustless and non-polluting. Combined with its near chemical purity, size consistency, and small grain structure, SandyCal possesses numerous advantages for the aragonite user, making it a superior source of calcium carbonate.
