Alternative method for the manufacture of granulated nutrients

摘要

Method of making a soil dispersible and water dispersible granular nutrient for use in fertilizers or animal feeds. A sulfuric acid solution is sprayed onto a mixture of reducible nutrient compounds and dry carbohydrates. The sulfuric acid converts the carbohydrates to their reducing forms. The reducing saccharides then react with the reducible nutrient compounds to form a carboxylated nutrient. The carboxylated nutrient is bound by polysaccharides and rolled up on itself to form a granule. The sulfuric acid also acts on the nutrient compounds directly to create sulfated nutrients. The process results in a product containing both carboxylated and sulfated metal nutrients.

1. A method for producing granulated nutrients for plants, the method comprising:
a. blending powdered oxide nutrients; b. mixing the powdered oxide nutrients with a dry carbohydrate source; and c. adding a sulfuric acid solution to the powdered oxide nutrients and the dry carbohydrate source to form carboxylate and sulfate nutrients.
