Out here in the southwest, calcium deficiency in
native soils in suburban areas is rarely a problem. However I do have agricultural customers in other regions that need supplemental Ca for a variety of reasons. One approach is to purchase soluble gypsum from an agricultural supplier. In ag dosages it will be completely soluble in non-alkaline water. I supply two other supplements to address the problem:
Maxi-Cal 10-0-0 which is popular in hydroponics, and
Phos Pro Calcium which is a mainstay of commercial fruit & nut orchards in California's central valley.
