Water soluble polymeric compositions are provided including at least one polyanionic polymer component (e.g., a copolymer containing maleic and itaconic repeat units), and at least one high molecular weight component selected from copolymers different than the polyanionic polymer and preferably having dicarboxylic repeat units, and a cellulose or cellulose derivative. The compositions are preferably substantially free of hydrocarbons and can be used to coat solid fertilizers in order to reduce fines.
