Uppdatering av kvävegödslingsrekommendationer för vall
Frankow-Lindberg, BodilAbstract
This report contains a meta-analysis of results from field trials with nitrogen application to leys which
were carried out during 1997-2015. The analysis deals with the response to nitrogen fertilisation with
respect to dry matter and crude protein content in the harvested biomass. The analysis shows that the
yield level without any nitrogen application, and the response to nitrogen (kg dry matter/kg N applied),
is greater in these trials compared to data from older trials. This applies to both pure grass leys and
mixed grass/clover leys. The crude protein content is positively correlated with nitrogen application in
pure grass leys. In mixed grass/clover leys this response depends on clover content, but is generally
negative in the last cut.
