Most useful on row crops being grown on calcareous soils where calcium and magnesium supplements are often required.
KeyPlex Calcium-Magnesium-Boron Plus is a formulation of chelated calcium, chelated magnesium and boron. 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-Boron Plus is formulated for foliar or drench application to prevent and correct calcium, magnesium and boron deficiencies in plants when used as directed.
KeyPlex Calcium-Magnesium-Boron Plus can be used in combination with pesticides. However, in unfamiliar mixtures use a “jar compatibility” test.
