What is the difference between a chelated calcium and complexed calcium?
A chelate and a complexing agent are somewhat similar in the fact they form a claw or ring formation around the metal ion, in this case a calcium ion. They actually sequester the metal, changing the charge and form a new molecule. A chelate attaches itself to two or more sites on the metal ion creating a very tight bond. A complexed ion is only attached at one site, allowing for quicker release of the calcium. A problem with a synthetic chelate, such as EDTA, is the molecule formed maybe larger than the leaf pores absorbing the calcium, making it difficult to enter. Secondly, the calcium ion is held so tightly that the rate of release of the calcium is very slow. Thirdly, once the calcium ion is released the plant has to use up considerable net energy to metabolize it or remove it from the plant. Chelates have shown to be very efficient in soil applications, but less so when applied directly to plant foliage. Nutri-Cal® is a natural organic complexed calcium source. T.O.G, the natural
