1. A METHOD OF SUPPLYING METALLIC MICRONUTRIENTS TO PLANTS AT A CONTROLLED RATE WHICH COMPRISES THE STEPS OF: A. PREPARING A NATURAL CATION CLAY BY CONTACTING A HYDROGEN CLAY IN AN AQUEOUS SLURRY WITH AN EQUIVALENT AMOUNT OF A SALT CONTAINING A CATION TO BE EXCHANGED IN THE PRESENCE OF AN ANION-EXCHANGE RESIN IN THE HYDROXIDE STATE, THEREBY EXCHANGING QUANTITATIVVELY THE CATIONS OF THE SALT FOR THE ADSORBED HYDROGEN OF THE CLAY, AND THEREAFTER RECOVERING AN ACID-FREE SALT-FREE CATION CLAY, AND B. TREATING PLANTS SUFFERING A MICRONUTRIENT DEFICIENCY WITH SAID CATION CLAY IN AN AMOUNT SUFFICIENT TO CORRECT, AT LEAST IN PART, SAID DEFICIENCY BY THE CONTROLLED TRANSFER OF SAID METALLIC MICRONUTRIENT FROM THE CLAY TO THE PLANTS.
2. The method of claim 1 wherein the clay-attached micronutrient comprises iron clay, zinc clay, manganese clay, copper clay and combinations aNd mixtures thereof.
3. The method of claim 1 which includes treating the plants by applying the clay-attached micronutrient to the foliage of the plants.
4. The method of claim 1 wherein treating the plants includes injecting into the plants the clay-attached micronutrient.
5. The method of claim 1 wherein treating the plants includes adding to the soil in proximity to the root structure of the plants the clay-attached micronutrient.
6. The method of claim 1 wherein the clay is a hydrogen-free montmorillonite clay.
7. The method of claim 1 which includes treating the plants by placing the clay-attached micronutrient in an aqueous suspension in an amount ranging from about 0.1 to 6.0% by weight of the micronutrient.
8. The method of claim 1 which includes treating the plants with a clay-attached micronutrient having a particle size of from about 0.1 to 5 microns by 0.01 to 0.02 microns.
