摘要：
The subject matter comprises shaped mixtures of valuable materials for the stimulation and cultivation of plant growth, said materials containing plant nutrients and/or plant-protective agents in admixture with a thermoplastic binder. According to the invention the mixtures of valuable materials, which mixtures have in particular been shaped as fertilizer rods, are characterized in that they contain, as the binder, a starch that has been thermomechanically digested at elevated pressures and temperatures.The invention further relates to the process for producing these multi-component mixtures and to the use of thermomechanically digested starch, optionally in admixture with inferior amounts of further biologically compatible binder components, as a biologically degradable binder for mixtures of valuable materials of the type described.
