Abstract
The phosphonitrilic hexamides (PNH) [N-15(6)] hexamino-phosphatriazine and hexaminophospha[N-15(3)] triazine were synthesized. Vegetation ex periments showed that PNH has a favourable effect on the maize growth. Also the results demonstrated that the major part of PNH is mineraliz ed during the following days. This process diminishes after 60 days. T he total N-fertilizer uptake is about 46%, 29% of which came from amin o-N and 17% from cyclic N, respectively. PNH behaved as a slow releasi ng N-fertilizer.
