Peat moss is prepared in the form of coherent cakes by drying granulated moss peat until the moisture content thereof is reduced to 10 to 30 percent by weight, and then compressing the thus-dried moss peat in a mold at a pressure between 1 and 4 British tons/in.2 until upon releasing the pressure the moss peat has the form of a cake having between one-sixth and one-twelfth its bulk size before compression. The coherent cake is easily reconstituted by wetting, and to this end may include a non-ionic wetting agent.
