A value-added granulated organic fertilizer produced from poultry litter and biosolids using agglomeration techniques with a pin mixer. The granulated organic fertilizer includes granules biosolids, a nitrification inhibitor, such as dicyandiamide, and a binding agent, such as lignosulfonate, urea formaldehyde, or water. The nitrogen concentration of the granulated organic fertilizer is increased by being fortified with urea. The poultry litter and biosolids formulated into the granulated organic fertilizer aid in flowability, storage, and spreading, while value-added plant nutrient ingredients provide an environmentally safer fertilizer than fresh poultry litter, municipal biosolids and/or many commercially available products commonly used in urban and agricultural systems. The binding agents change the fertilizer granule water soluble phosphorus and nitrogen concentrations and reduce fines and dust. The nitrification inhibitor reduces nitrogen losses via leaching and denitrification, while biosolids decrease water soluble and total phosphorus concentrations in runoff water for environmental protection.
