Antagonism Between Molybdenum and Certain Heavy Metals in Plant Nutrition

Abstract

IT has been recognized in the literature that an excess of either manganese, zinc, copper, cobalt or nickel will induce iron-deficiency chlorosis in plants. Other toxic effects such as stunting and lower leaf necrosis may also occur. These effects have been confirmed in water-culture experiments with flax, conducted at the Plant Research Laboratory, Department of Agriculture, Burnley, Victoria.
