Abstract [en]

This study evaluated losses of N2O, CH4 and NH3 from a rotational grazing system for overwintering beef cattle which spend 1 month on pasture. The cattle density was 71 heifers/ha and they were moved weekly to a new feeding area within the main pasture. The N2O, CH4 and NH3 losses were determined in two feeding areas that were severely trampled (ST) or less trampled (LT) and in a control area from which cattle were excluded. The N input to the pasture was measured. The NH3 losses were measured by micrometeorological mass balance in two periods with heifers present. The N2O and CH4 were measured using a closed chamber method with 9 chambers within each area on 10 occasions after heifers were removed from the pasture. The N input was 510kgN/ha. The NH4-N contents in the clay loam topsoil were 45, 28 and 11kg/ha in the ST, LT and control areas, respectively. Losses of NH3 were low due to rainy and cold conditions, corresponding to maximum 0.3kgN/ha/d. The soil was water logged and this, with the cold conditions, may have lowered N2O emissions. Maximum N2O losses were 7, 30 and 18gN2O-N/ha/d from ST, LT and control areas, respectively.
