Somers and Shive (37) suggested that the physiological availability of iron in plants is determined by the relative manganese supply and that the optimum growth and yield of plants depend on a certain definite proportion rather than the absolute level of iron and manganese supply. These workers also held that iron deficiency is identical with manganese… (More)
