Fertilizers containing animal nutrient core packet

Abstract

A fertilizer supplying animal nutrients including a core particle having an outer surface and comprising compounds containing animal nutrients, and a coating of urea on the outer surface of the core particle, and further a process of making the fertilizer including the steps of: screening animal nutrient core particles comprising a powdered substance containing an animal nutrient, to a preselected particle size; spraying melted urea onto the surface of the nutrient core particles to produce a coating on the nutrient core particles; granulating the nutrient core particles with sprayed melted urea to produce nutrient core granules; and cooling the nutrient core granules.

         16 . A method of alleviating or eliminating nutrient deficiencies in animals by growing animal nutrient enriched food plants, comprising the following steps:
 a) determining a deficiency of an animal nutrient in an animal;   b) determining the amount of the animal nutrient in a food plant grown on a specific soil;   c) determining the amount of the animal nutrient in the soil;   d) determining the amount of animal nutrient required to be applied to the soil to increase the amount of the animal nutrient in the food plant;   e) selecting the animal nutrient in a fertilizer comprising a core particle comprising one or more compounds comprising animal nutrients, an outer surface, and a first coating of urea on the outer surface, to be the nutrient determined in step a) and adjusting the amount of the selected nutrient to provide the determined amount of nutrient in step d); and   f) applying the fertilizer resulting from step e) to said specific soil.   
     
     
         17 . The method of  claim 16 , wherein the animal is a human. 
     
     
         18 . The method of  claim 16 , wherein the urea in the first coating is from 84.4 to 98.7%. 
     
     
         19 . The method of  claim 16 , wherein the first coating further comprises a coating material selected from the group consisting of ureaform, water soluble urea formaldehyde polymer, water insoluble urea formaldehyde polymer, methylene urea, methylene diurea, dimethylenetriurea, urea formaldehyde, and combinations thereof. 
     
     
         20 . The method of  claim 16 , wherein the one or more compounds comprising animal nutrients are selected from the group consisting of vitamin A, vitamin C, vitamin D, vitamin E, vitamin K, thiamin, riboflavin, niacin, vitamin B6, folic acid, vitamin B12, biotin, pantothenic acid, iron, iodine, magnesium, zinc, selenium, copper, manganese, chromium, molybdenum, chloride, boron, nickel, silicon, tin, vanadium, lutein, lycopene, and combinations thereof. 
     
     
         21 . The method of  claim 16 , wherein the selected nutrient of step e) is selected from the group consisting of iodine, iron, zinc, vitamin A, and combinations thereof. 
     
     
         22 . The method of  claim 21 , wherein the selected nutrient of step e) is zinc. 
     
     
         23 . The method of  claim 16 , wherein the fertilizer further comprises a second coating of urea on the first coating of urea, the second coating containing plant nutrients selected from the group consisting of phosphorus compounds, potassium compounds, and a combination thereof.
