How to read the number
Mn yellows new leaves between veins, often with brown or grey specks. Wheat shows it clearly. Too acid or too alkaline both scramble it. High-organic calcareous soils can lock it too Easy to mix up: Iron rarely speckles; manganese often does. Read pH; don’t tank-mix a micronutrient blast Available Mn is manganese on new leaves.
