WCA (Water Soluble Calcium) is extracted from the eggshells of our chickens using Brown Rice Vinegar. Eggshells on their own need to be finely ground in order to be useful to the soil. Using this method makes the calcium immedietly available to the plants in either foliar or soil application. WCA is used during the Reproductive phase of a plant.
