Abstract
Compositions for the treatment of granular fertilizers containing secondary C.sub.14 -C.sub.20 dialkyl monoamines or their mixture with primary monoamines which are also C.sub.14 -C.sub.20 have the advantage of limiting both the solidification and the secondary production of dust on storage. The process is particularly advantageous in the treatment of NPK-type fertilizers.
