Synthetic metal chelates have been used effectively to make iron available to plants in soils. Agricultural use of chelates has been influenced by cost of the materials, their stability, pH of the soil, and the kind of crop. There is competition between chelating agents and between roots and chelating agents, for nutrient elements. Differential uptake of the metal and ligand by the plant has been demonstrated. The use of synthetic metal chelates in agriculture appears as a stop‐gap measure until a more permanent solution is obtained for some of our micronutrient problems. Genetic variants as factors affecting plant nutrition may provide the permanence sought by providing a plant adapted to a particular soil.
