More Info

KeyPlex Calcium Plus is a formulation of chelated calcium. It contains alpha-keto acids, which may facilitate utilization of micronutrients, and increase resistance to environmental stress. It also contains humic acid, which may enhance soil micronutrient availability. KeyPlex Calcium Plus is formulated for foliar or drench application to prevent and correct calcium deficiency in plants when used as directed.


KeyPlex Calcium Plus may be used in combination with pesticides. However, in unfamiliar mixtures use a “jar compatibility” test.
