Effects of traffic and fertilization levels on grass yields in northern Norway
Experiments with various traffic regimes in grassland (no traffic, light and medium tractor with two mechanisation lines; forage harvester and two-step harvesting) and three fertilization levels (N 120, 180, 240 kg ha-1) were carried out in five fields on sandy soils and peat soils in Bodø, northern...
