Lime-induced chlorosis is an important–and widespread–nutritional disorder of plants in California and other western states. Trees and shrubs are especially susceptible on soils containing calcium carbonate–lime. Although the chlorosis responds variously to iron compounds, it appears to be more complicated than a simple iron deficiency because yellow, chlorotic leaves sometimes contain more iron than healthy green leaves.
