We constructed a roof below the canopy of a 65-year-old Norway spruce forest (Picea abies (L.) Karst.) and simulated two climate change scenarios: (1) an extensively prolonged summer drought of 172 days followed by a rewetting period of 19 days in 1993 and (2) a less intensive summer drought of 108 days followed by a rewetting period of 33 days in 1994. CH4 oxidation, soil matric potential, and soil temperature were measured hourly to daily over a a-year period. The results showed that annual CH4 oxidation in the drought experiment increased by 102% for the climate change scenario 1 and by 41% for the climate change scenario 2, compared to those of the ambient plot (1.33 kg CH4 ha(-1) in 1993 and 1.65 kg CH4 ha(-1) in 1994). We tested the relationships between CH4 oxidation rates, water-filled pore space (WFPS), soil matric potential, gas diffusivity, and soil temperature. Temporal variability in the CH4 oxidation Fates corresponded most closely to soil matric potential. Employing soil matric potential and soil temperature, we developed a nonlinear model for estimating CH4 oxidation rates. Modeled results were in strong agreement with the measured CH4 oxidation for the ambient (r(2) = 0.80) and drought plots (r(2) = 0.89) over two experimental years, suggesting that soil matric potential is a highly reliable parameter for modeling CH4 oxidation rate."],["dc.identifier.doi","10.1029/1999JD901170"],["dc.identifier.isi","000086095000002"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/18591"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Amer Geophysical Union"],["dc.relation.issn","2169-897X"],["dc.title","Effects of prolonged soil drought on CH4 oxidation in a temperate spruce forest"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]

A beta function is used to characterize the effect of soil water on the physical limitation of gas diffusivity when water is high and biological limitation when water is low. Optimum soil volumetric water content (W-opt) increases with FC. The site specific maximum CH4 oxidation rate (CH4max) varies directly with soil gas diffusivity (D) as a function of soil bulk density and FC. Although soil water content and physical pro are the primary controls on CH4 uptake, the potential for soil temperature to affect CH4 uptake rates increases as soils become less limited by gas diffusivity. Daily CH4 oxidation rate is calculated as the product of CH4max, the normalized (0-100%) beta function to account for water effects, a temperature multiplier, and an adjustment factor to account for the effects of agriculture on methane flux. The model developed with grassland soils also worked well in coniferous and tropical forest soils. However, soil gas diffusivity as a function of field capacity, and bulk density did not reliably predict maximum CH4 oxidation rates in deciduous forest soils, so a submodel for these systems was developed assuming that CH4max is a function of mineral soil bulk density.

Soil compaction in the middle of the wheel track caused a considerable increase of N2O emissions with values elevated by up to 40 times the uncompacted ones. Compaction reduced the CH4 consumption at all sites by up to 90%, and at the silty clay loam site its effect was such that CH4 was even released. These changes in N2O and CH4 fluxes were caused by a reduction in macropore volume and an increase of the water-filled pore space (WFPS). Additionally, the slipping of the forwarder's wheels led to a mixing of the humus layer with the mineral soil, which resulted in a new layer. This layer reduced gas exchange between the soil and the atmosphere. Trace gas fluxes were altered in the trafficked soil and in the adjacent areas. Despite the significant changes in the trace gas fluxes on the skid trails, the cumulative effect of the two gases on the atmosphere was small with respect to total emissions.

This land-use conversion caused a reduction of soil organic carbon (SOC) stocks by on average 19% down to 1.2 m over 46 years. Due to the mountainous topography of the region, most rubber plantations include narrow terraces parallel to contours. Manual terrace construction involves cutting of the soil from the upper slope and piling up the removed soil on the soil surface downslope. Soil redistribution by terrace construction may affect SOC dynamics through exposure of the subsurface soil at the terrace inner sides (cut section) and soil burial at the terrace outer edges (fill section).Our study, conducted in southern Yunnan province of China, aimed to quantify SOC stock changes induced by terrace construction. In three rubber plantations aged 5, 29 and 44 years, we systematically sampled the terraces according to soil redistribution zones, and the original sloping areas in between the terraces were used as reference.At the cut section of the terrace, topsoil removal caused a depletion of SOC stocks in the youngest plantation followed by SOC stock recovery in the two oldest plantations. The recovery of SOC stocks at the cut section in the two oldest plantations was attributed to the capacity of the exposed subsurface soil to store new organic carbon inputs from roots and litter, and to sedimentation of eroded topsoil materials from the upper slope. At the fill section of the terrace, soil deposition resulted in higher total SOC stocks compared to the reference position in all plantations. This was due to the deposition of redistributed soil material on top of the original soil surface combined with the partial preservation of carbon in the buried soil. Overall, the increase of SOC in the exposed subsurface soil at the cut sections, and the partial preservation of SOC in the buried soil at the fill sections resulted in higher SOC stocks down to 1.2 m at the terraces compared to the reference positions in the two oldest plantations.

Using chamber techniques, we measured monthly flux rates and controlling factors on three elevations, each with three replicate plots for 1 year. Annual N2O fluxes ranged from 0.29 kg N ha−1 yr−1 at 1800 m to 1.01 kg N ha−1 yr−1 at 2470 m and 1.11 kg N ha−1 yr−1 at 1190 m, while annual NO fluxes ranged from 0.17 kg N ha−1 yr−1 at 1800 m, to 0.18 kg N ha−1 yr−1 at 2470 m and 0.48 kg N ha−1 yr−1 at 1190 m.

Early ideas that we should be able to use the large body of existing research on terrestrial N cycling to predict patterns of N(2)O flux at the ecosystem scale have been hard to prove due to extreme temporal and spatial variability in flux. The vast majority of the N(2)O flux measurement and modeling activity that has taken place has been process lever and field scale, i.e., measurement, analysis and modeling of hourly and daily fluxes with chambers deployed in field plots. It has been very difficult to establish strong predictive relationships between these hourly and daily fluxes and field-scale parameters such as temperature, soil moisture, and soil inorganic N concentrations. In this study, we addressed the question of whether we can increase our predictive understanding of N(2)O fluxes by examining relationships between flux and environmental parameters at larger spatial and temporal scales, i.e., to explore relationships between annual rather than hourly or daily fluxes and ecosystem-scale variables such as plant community and soil type and annual climate rather than field-scale variables such as soil moisture and temperature. We addressed this question by examining existing data on annual fluxes from temperate forest, cropland, and rangeland ecosystems, analyzing both multiyear data sets from individual sites as well as cross-site comparison of single annual flux values from multiple sites. Results suggest that there are indeed coherent patterns in annual N(2)O flux at the ecosystem scale in forest, cropland, and rangeland ecosystems but that these patterns vary by region and only emerge with continuous (at least daily) flux measurements over multiple years. An ecosystem approach to evaluating N(2)O fluxes will be useful for regional and global modeling and for computation of national N(2)O flux inventories for regulatory purposes but only if measurement programs are comprehensive and continuous."],["dc.identifier.doi","10.1029/1999GB001227"],["dc.identifier.isi","000166341000006"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/45785"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Amer Geophysical Union"],["dc.relation.issn","0886-6236"],["dc.title","Evaluating annual nitrous oxide fluxes at the ecosystem scale"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]
