“…The experiments were carried out at the moderately cattle-impacted locality in a cattle overwintering area at the Borová Farm, Southern Bohemia (Šimek et al 2006(Šimek et al , Hynšt et al 2007a. The soil on the site is a sandy loam haplic phaeozem (arenic; WRB system) containing 60-80% sand, 14-32% silt, and 6-14% clay (USDA classification system).…”

“…Field measurements were conducted in three seasons: in early May (when high N 2 O emissions were expected; Hynšt et al 2007a), in mid-July, and in early November. The flux measurements always started at 9 a.m. For each measurement, the chambers were closed and gas samples were taken at time 0 and 60 min.…”

“…Gas fluxes were determined using non-vented manually closed chambers (Hynšt et al 2007a), buried 5 cm in soil and spatially distributed. The amounts of N 2 O and CO 2 were quantified using an HP 5890 gas chromatograph and an HP P200H Portable Gas Microchromatograph (both Hewlett Packard, USA).…”

“…On the other hand, emissions of CO 2 , which is also produced during decomposition of excrements, are normally less heterogeneous. In our previous investigations, a cattle overwintering area in South Bohemia was identified as an important source of N 2 O because of substantial excrement deposition, impacts on soil physical properties, and limited N use by plants in winter (Šimek et al 2006(Šimek et al , Hynšt et al 2007a). …”

Short-term diurnal changes in emissions of CO 2 and N 2 O were determined in a cattle overwintering area during three specific periods of the year. Production of both N 2 O and CO 2 , as determined with gas chambers buried in soil and spatially distributed changed rapidly, and the general course of fluxes of the two gases was different. CO 2 emissions were basically controlled by temperature, and most gas chambers showed the same trends in CO 2 flux, indicating low spatial heterogeneity. In contrast, N 2 O emissions were much more spatially heterogeneous and each chamber had its own time course of emission; therefore, the relationship between flux and temperature was more complicated for N 2 O than CO 2 . For estimating gas emissions over long periods, we strongly recommend the use of frequent emission measurements during periods of high gas fluxes.

“…Both denitrification potentials and nitrous oxide (N 2 O) emissions increased in response to grazing. This occurred because major factors controlling denitrification, such as nitrate (NO 3 − -N), C, soil moisture, and soil compaction, increased, which led to increased nutrient input and oxygen-limiting conditions favoring denitrification (Chroňáková et al 2009;Hynšt et al 2007). …”

Evaluating the lingering effect of livestock grazing on functional potentials of microbial communities in Tibetan grassland soils

Background and aims Livestock grazing is a widely practiced land-use regime that can impose lingering effects on global biogeochemical cycles. However, elucidating the mechanisms of related eco-processes, which are largely mediated by the microbial community, remains challenging. Methods Here, we collected soil samples from two Tibetan grassland sites subjected to grazing in winter followed by a 3-month recovery. We then evaluated Plant Soil
