Abstract

Fertilizer granules and methods of producing fertilizer granules. The fertilizer granules are formed from a fertilizer composition, such as a phosphate fertilizer, includes a fibrous material for the purpose of increasing the granule strength preventing or reducing attrition or dusting formation during storage, transport, and/or handling of the fertilizer. Dust formation can be reduced fifty percent or more. The base fertilizer composition can include a phosphate fertilizer, such as monoammonium phosphate (MAP) or diammonium phosphate (DAP), and optionally one or more micronutrients or secondary nutrients, such as elemental sulfur. The fibrous material is pulp or paper sludge, for example.
