Organic Calcium and Sea Minerals

Why Coral Powder?

Calcium from coral is the most bioavailable (absorbable) source of calcium. At 37% concentration, coral powder provides the best value for this important nutrient. 1-4 applications of 2-4 pounds per acre may be used in a program to maintain sufficient levels of calcium in most crops. These are significantly lower application rates and quantities than traditionally applied products. Coral powder is extremely soluble, mixes well and poses no threat to users. 

Calcium is widely known as one of the most essential agricultural nutrients. Many types of calcium products are used to improve plant health, crop quality and storability.
Minerals From Fossil Coral

Because coral is formed biologically–not geologically–its organic composition becomes ionic calcium (CA++) in the presence of water. This composition is due to the digestion process of the animals that ingested calcium minerals from sea water millions of years ago.


Coral provides a highly-soluble mineral complex that is immediately available to plants. Plants can only utilize calcium ions in their growth processes. Any other soil applied salt must decompose into calcium ions before it can be used by plants.


Lime (calcium carbonate) and gypsum (calcium sulfate) are salts of low solubility and mostly unavailable to plants in soils. Their application rates are usually in tons per acre and can cause growers to experience soil disorders from high calcium levels.


The solubility and availability of coral provides sufficient calcium to crops when other inputs do not.

Nature's Multivitamin

Though coral may share some characteristics with calcium carbonate, research shows that it is quite different. 


This is due to its organic formation. In addition, coral contains 72 elements not contained in lime--25 of these are essential micronutrients. 60 are found in human milk and blood.

These micronutrients help facilitate plant uptake of calcium by balancing the plant and soil electrochemically. Coral is truly nature's complete multivitamin and one of the most available and natural forms of plant nutrients.


Plants and animals share in the benefits of coral whose effects were recognized by the ancient Egyptians.

Above Sea Coral

Because the origin of many islands in the oceans is coral, it is widely available. Much of the coral being mined today was deposited millions of years ago when the oceans were 200-300 feet higher and there was no ocean pollution. 


All of these factors contribute to a pure and very available source of calcium for agriculture as well as human medicine.


Fossil coral that has been pushed up onto land by natural processes is harvested and ground into 44 microns (325 mesh) for use as a foliar or ground applied input.


No living reefs are disturbed by the mining of fossil coral.
