Abstract

Described is a process for the manufacture of membrane-covered fertilizer granules by coating the granules with films of a mixture of a polyisocyanate and a polyol, the coating compound being applied in proportions such that each film has a thickness of 10 to 30 $g(m)m, preferably 15 to 20 $g(m)m. The granular fertilizer manufactured in this way has the advantage that it initially emphasizes nitrogen release and subsequently potassium release.
