More Info

KeyPlex Calcium-Magnesium Plus is a formulation of chelated calcium and magnesium. 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-Magnesium Plus is formulated for foliar or drench application to prevent and correct calcium and magnesium deficiency in plants when used as directed.


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