N2O emissions from low and moderately disturbed pasture soils - field tests of minimal and maximal N supply

Popis výsledku v původním jazyce

Rates and patterns of nitrogen transformation differ in divergently managed pasture soils. In pastures with low nutrient inputs, N is utilized efficiently and it is assimilated by plants and soil microorganisms for synthesis of biomass. In more intensivepastures, characterized with higher N inputs, significant amounts of N can be lost from the ecosystem in various forms. Two soils of a cattle overwintering area with different levels of cattle disturbance were supplied with a solution of KNO3 in variouslevels corresponding in range to 0-500 kg N ha-1 Emissions of N2O were measured during 24 h after a NO3--N application. We hypothesized that under a low disturbance small additions of up to 5 kg NO3--N are used by plants and soil microbes without an increase in N2O emissions, while a pasture adapted to a moderate disturbance will increase N2O emissions.
