Beschreibung
Zusammenfassung:	In the production of a solid composition (A) containing plant treatment active agents, coated with at least one biodegradable polymer layer, the polymer layer is prepared by treating the solid composition with a dispersion containing a polymer (I) having urethane and urea groups. An Independent claim is included for (I) obtained by the above process. Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung von festen, Nährstoffe für Pflanzen enthaltenden Mitteln mit wenigstens einer biologisch abbaubaren Polymerschicht, die hergestellt wird, indem man Dispersionen, enthaltend Polymere, die Urethan- und Harnstoffgruppen aufweisen, zur oberflächigen Behandlung von festen, Nährstoffe für Pflanzen enthaltenden Mitteln einsetzt.
