Superabsorbent polymer products for use in agricultural applications, and methods of making the same, are provided. The superabsorbent polymer is used in a seed coating along with an active ingredient, and optionally a singulating substance, to improve seed germination and/or blooming; improve germination under dry conditions; decrease irrigation requirements; increase propagation, crop growth, and crop production; and improve the efficacy of the active ingredient.

1. A method for coating a seed with a superabsorbent polymer seed coating to produce a coated seed product, consisting essentially of: providing a plurality of seeds;applying an active ingredient to the seeds, wherein the active ingredient is selected from at least one of the following: nutrients, plant growth regulators, insecticides, fungicides, herbicides, and biological materials;applying a superabsorbent polymer to the seeds; to form a mixture of seeds, active ingredient, and superabsorbent polymer; andapplying a singulating substance to the mixture, wherein the coated seed product is free of a binder or adhesive. 2. The method of claim 1, wherein the application of the singulating substance occurs after the addition of the superabsorbent polymer. 3. The method of claim 2, wherein the application of the singulating substance occurs within 5 seconds of the addition of the superabsorbent polymer. 4. The method of claim 2, wherein the application of the singulating substance occurs within 2 seconds of the addition of the superabsorbent polymer. 5. The method of claim 1, wherein the superabsorbent polymer is a starch-g-poly (2-propenamide-co-2-propenoic acid) potassium salt starch graft copolymer. 6. The method of claim 1, wherein the singulating substance is talc. 7. The method of claim 1, wherein the singulating substance is present at a rate of between about 0.05% and about 0.50% of the weight of the seed. 8. The method of claim 1, wherein the active ingredient is present at a rate of between about 0.01% and about 3.0% of the weight of the seed. 9. The method of claim 1, wherein the superabsorbent polymer is present at a rate of between about 0.10% and about 1.50% of the weight of the seed. 10. The method of claim 1, wherein the superabsorbent polymer is present at a rate of between about 0.2% and about 0.4% of the weight of the seed. 11. The method of claim 1, wherein the seed is selected from at least one of the following: corn, soybeans, wheat, cotton, sunflowers, sorghum, canola, vegetables, barley, oats and other small grains, dry beans, peas, lentils, and peanuts. 12. A method for coating a seed with a superabsorbent polymer seed coating to produce a coated seed product, comprising: providing a plurality of seeds;applying an active ingredient to the seeds, wherein the active ingredient is selected from at least one of the following: nutrients, plant growth regulators, insecticides, fungicides, herbicides, and biological materials;applying a superabsorbent polymer to the seeds; to form a mixture of seeds, active ingredient, and superabsorbent polymer; andapplying a singulating substance to the mixture, wherein the coated seed product is free of a binder or adhesive.
