    摘要: A dry, flowable fertilizer is provided that includes multiple dry, flowable biosolids pellets. Each of the pellets has a pellet surface. Potassium salt grains are adhered to the pellet surfaces and a dust control agent coating is applied to retain the grains on the pellet surfaces. The resultant dry, flowable fertilizer has higher potassium loadings to the potassium salt grains than previous biosolids based fertilizers. A process of forming a fertilizer is also provided that includes tumbling dry, flowable biosolids pellets with powdered potassium salt grains to form a mixture. An aqueous spray is added to adhere the salt grains to the pellet surfaces. With the application of a dust control agent, the salt grains are retained. Potassium levels in NPK units of from 1 to 15 are routinely achieved with greater than 90 elemental % of the potassium is from the surface decorating potassium salt grains.
