Neue Anbietungsform eines organischen Düngemittels und Verfahren zu seiner Herstellung

摘要

Described is a method of manufacturing a granular plant growth promotion agent with properties which make it acceptable in use - in particular the fact that it is essentially odourless and does not form dust - and with a long-term fertilizer action, thus making it suitable for use, in particular, on a small scale in house and garden. The fertilizer is obtained in this novel form by drying, in a fluidized-bed drier using superheated steam as the drying gas, biomass residues from the production of recuperable materials using biotechnological techniques - if necessary utilizing, in addition, other recuperable materials and/or auxiliaries.
