EFFECTIVENESS OF PERMANENT MEADOW FOLIAR FERTILISATION WITH NITROGEN
Kazimierz Jankowski, Joanna Jodelka, Roman Kolczarek
In the present research an effectiveness of soil fertilisation with lower dosages of nitrogen combined with top supplying with a 10% water solution of carbamide was compared with that of the standard test soil fertilisation (PK + 220kg N/ha). A similar reaction of meadow sward in both cases of nitrogen feeding was observed. Fertilising the soil only with 55 kg of N/ha along with foliar fertilisation caused neither a decrease in the yield nor its quality. The application of the second spray for the second cut did not cause any decrease in yield, however it had positive effect on the content of total protein and crude fibre in the feed. A significant impact of the subsequent years of fertilisation on the combined effect of soil and foliar nitrogen fertilisation with carbamide solution was noted.
Key words: grassland, yielding, total protein, crude fibre, soil nitrogen fertilisation, foliar fertilisation with carbamide..
