The costs associated with biosolids products will vary based on the specific biosolids product – biosolids come in a variety of forms including lime-stabilized cake and digested cake (similar to pen-pack manure), compost, and thermally dried granules (similar to granular fertilizers). Most biosolids products are compatible with most manure spreaders. The specific cost arrangement between the utility and the farmer varies on a case-by-case basis and will be discussed at the initial phase of program entry.
