Summary This paper reports the range and statistical distribution of oxidation rates atmospheric CH 4 in soils found Northern Europe an international study, compares them with published data for various other ecosystems. It reassesses size, uncertainty in, global terrestrial sink, examines effect land‐use change factors on rate. Only a very high water table were sources ; all others sinks. Oxidation varied from 1 to nearly 200 μg m −2 h −1 annual sites measured ≥1 y 0.1–9.1 kg ha ,...
Organic reduced tillage aims to combine the environmental benefits of organic farming and conservation increase sustainability soil quality. In temperate climates, there is currently no knowledge about its impact on greenhouse gas emissions only little information carbon (SOC) stocks in these management systems. We therefore monitored nitrous oxide (N2O) methane (CH4) fluxes besides SOC for two years a grass-clover ley – winter wheat cover crop sequence. The monitoring was undertaken an...
Crop residue incorporation is a common practice to increase or restore organic matter stocks in agricultural soils. However, this often increases emissions of the powerful greenhouse gas nitrous oxide (N2O). Previous meta-analyses have linked various biochemical properties crop residues N2O emissions, but relationships between these been overlooked, hampering our ability predict from specific residues. Here we combine comprehensive databases for and characteristics with random-meta-forest...
Crop residues are important inputs of carbon (C) and nitrogen (N) to soils thus directly indirectly affect nitrous oxide (N2 O) emissions. As the current inventory methodology considers N by crop as sole determining factor for N2 O emissions, it fails consider other underlying factors processes. There is compelling evidence that emissions vary greatly between with different biochemical physical characteristics, concentrations mineralizable decomposable C in residue biomass both enhancing...
Abstract. The emissions of nitrous oxide (N2O) and leaching nitrate (NO3) from agricultural cropping systems have considerable negative impacts on climate the environment. Although these environmental burdens are less per unit area in organic than non-organic production average, they roughly similar product. If farming is to maintain its goal being environmentally friendly, loadings must be addressed. We discuss impact possible drivers N2O NO3 within arable practice under European climatic...
The oxidation of atmospheric methane in soils was measured situ at a selection sites northern Europe, mainly under forest but also moorland and agricultural arable land grassland. Our objective to examine how use, soil type, location affected through their impact on gas diffusivity air permeability. Gas the surface and, some cases, after removal any organic layer using Freon‐22 tracer portable probe. For about half sites, intact topsoil core samples laboratory krypton 85. Air permeability...
Background: During the initial steps of green biorefining aimed at protein recovery, endogenous proteins and enzymes, along with, e.g., phytochemical constituents, are decompartmentalized into a juice. This creates highly dynamic environment prone to plethora reactions including oxidative modification deterioration. Obtaining fundamental understanding enzymes capable exerting antioxidant activity ex vivo could help mitigate these for improved product quality. Methods: In this study, we...
Abstract. Legumes are an important source of nitrogen in stockless organic cereal production. However, substantial amounts N can be lost from legume-grass leys prior to or after incorporation as green manure (GM). Here we report N2O emissions a field experiment SE Norway exploring different management strategies: mulching versus removal grass-clover herbage during whole growing season and return biogas residue subsequent barley crop. Grass-clover ley had small but significantly higher...
Understanding soil sulfur pools and associated aggregates S fractions can provide a platform for monitoring dynamics in soils. A long‐term experiment established 1922 on an Aquic Eutrocryepts South‐eastern Norway was chosen to investigate the effects of fertilization bulk those with aggregates. Chloroform fumigation‐extraction used determine Microbial biomass (MBS) wet chemical analysis method fractionate into ester (hydriodic acid reducible S), carbon‐bonded (Raney nickel S) residual...
In this study, 200 Norwegian dairy farms were analyzed over three years to compare greenhouse gas emissions, nitrogen (N) intensity, gross margin, and land use occupation between organically conventionally managed farms. Conventionally farm groups constructed based on propensity matching, selecting the closest counterparts (n=15). These groups, each containing 15 farms, differentiated by an increasing number of matching variables. The first group was matched geographical location, milk...
