Calcium (symbol Ca) is found mainly in the leaves and roots of plants, and primarily in the points of growth of the leaves and the tips of the roots. The correct ratio between calcium, magnesium and potassium is important because all plant functions depend on this ratio. Calcium is added to the nutrient solution in the form of superphosphate, monocalcium phosphate, gypsum, calcium sulfate or nitrate.
