15. A water-dispersible particle comprising:
a nitrogen containing ingredient bioavailable to a targeted desirable plant as a fertilizer and present in an amount ranging from 5% to 99.9% by weight of the total dry weight of the particle and selected from the group consisting of: ammonium nitrate, ammonium sulfate and urea; and
binder component composed of a protein mechanical aggregating fines of said nitrogen containing ingredient, said binder component present in an amount ranging from 1% to 95% by weight of the total dry weight of the particle, the particle having a mean particle domain size of from 0.1 to 30 millimeters;
the nitrogen containing ingredient and the binder component present in an intermixed form such that one of the particle having the mean particle domain size of 0.5 millimeters having contact with water causes particle dispersion into from 100 to 10,000 pieces in a time period of 30 seconds to 1 hour; and
wherein the particle further comprises an adhesive.
16. The particle of claim 15 further comprising an active ingredient.
17. The particle of claim 16 wherein the active ingredient is selected from the group consisting of: a soil nutrient, an amendment material, and a combination thereof.
18. The particle of claim 17 wherein the soil nutrient is selected from the group consisting of: calcium, magnesium, sulfur, iron, manganese, copper, zinc; oxides thereof; salts thereof, and a combination thereof.
19. The particle of claim 16 wherein the active ingredient is selected from the group consisting of: a biological factor and a biostimulant;
wherein the biological factor is selected from the group consisting of: an algicide, a bacteriocide, a defoliant, a desiccant, a fungicide, an herbicide, an insecticide, an insect growth regulator, a miticide, a nematicide, an ovicide, a pesticide, a pheromone, a repellent and a rodenticide, and a combination thereof; and
wherein the biostimulant is selected from the group consisting of: a plant growth hormone and a plant growth regulator, and a combination thereof.
