Dissolved organic matter (DOM) plays a central role in driving soil biogeochemistry, but little information is available on the effects of plastic residues, especially microplastic, on soil DOM. We conducted a soil-incubation experiment in a climate-controlled chamber with three levels of microplastic added to loess soil collected from the Loess Plateau in China: 0% (control, CK), 7% (M1) and 28% (M2) (w/w). We analysed the soil contents of dissolved organic carbon (DOC), dissolved organic nitrogen (DON), NH4+, NO3-, dissolved organic phosphorus (DOP), and PO43- and the activities of fluorescein diacetate hydrolase (FDAse) and phenol oxidase. The higher level of microplastic addition significantly increased the nutrient contents of the DOM solution. The lower level of addition had no significant effect on the DOM solution during the first seven days, but the rate of DOM decomposition decreased in M1 between days 7 and 30, which increased the nutrient contents. The microplastic facilitated the accumulation of high-molecular-weight humic-like material between days 7 and 30. The DOM solutions were mainly comprised of high-molecular-weight humic-like material in CK and M1 and of high-molecular-weight humic-like material and tyrosine-like material in M2. The Microplastic stimulated the activities of both enzymes. Microplastic addition thus stimulated enzymatic activity, activated pools of organic C, N, and P, and was beneficial for the accumulation of dissolved organic C, N and P.", "keywords": ["2.

A series of field experiments were carried out during October 2004 and September 2007 in a lysimeter field to reveal the temporal changes of N leaching losses below 2-m depth from this land system as well as the effects of N fertilizer application rates on N leaching. Four N rates (0, 180, 260, and 360 kg N ha(-1) as urea) were applied in the study area.

The average seasonal flow-weighted NO(3)-N concentrations in leachate for the four N fertilizer application rates ranged from 8.1 to 103.7 mg N l(-1), and seasonal flow-weighted dissolved organic nitrogen (DON) concentrations in leachate varied from 0.8 to 6.0 mg N l(-1). Total amounts of NO(3)-N leaching lost throughout the 3 years were in the range of 14.6 to 177.8 kg ha(-1) for the four N application rates, corresponding to N leaching losses in the range of 4.0-7.6% of the fertilizers applied.

Thinning of native forests helps to preserve native tree species and is more sustainable than replacing native forest stands with mono-species plantations to produce timber. This study aimed to explore the effects of native forest thinning on soil-plant carbon (C) and nitrogen (N) dynamics in two experimental sites, Esk (5\u00a0years post-thinning) and Herberton (7\u00a0years post-thinning), situated in Queensland, Australia. The two sites had different thinning regimes. The final stocking rates varied between 75 and 200 stems ha\u22121 at Esk and between 250 and 400 stems ha\u22121 at Herberton. The thinned plots were compared to un-thinned plots. Soil samples were collected to measure labile C and N. Leaf samples were collected from C. variegata and C. citriodora in Esk and Herberton respectively. Thinning did not change soil total C, total N, \u03b415N and inorganic N at either Esk or Herberton. However, at Esk, intensive thinning resulted in decreases in water soluble total N (WSTN). Foliar \u03b413C did not vary with respect to thinning whereas foliar \u03b415N values were more enriched in thinned areas than those of un-thinned plots. The stepwise linear regression indicated that both foliar total N and \u03b415N were explained mainly by soil TN and WSTN. Thinning did not change soil C and N most likely due to the retention of thinned materials on site and their incorporation into soil. Foliar \u03b413C was not thinning-dependent due to homeostatic maintenance of the ratio of intercellular to ambient CO2 concentrations during photosynthesis. In our study, soil N was not a limiting factor for foliar N, however, foliar N was mainly driven by WSTN which may foreshadow a possible N limitation in severely thinned plots in the long term. We conclude that forest thinning does not decrease soil C and N availability in native Corymbia forests for several years post-thinning if the thinned materials are retained on site.", "keywords": ["570", "Corymbia spp", "Inorganic nitrogen", "stable isotopes", "veterinary and food sciences", "eucalyptus spp", "Other environmental sciences not elsewhere classified", "FoR 06 (Biological Sciences)", "Stable isotopes", "Farm forestry", "580", "Agricultural", "farm forestry", "FoR 07 (Agricultural and Veterinary Sciences)", "inorganic nitrogen", "04 agricultural and veterinary sciences", "15.

Evidence From An Ecotonal Climosequence", "description": "Abstract   As the largest actively cycling pool of terrestrial C, the response of soil organic matter (SOM) to climate change may greatly affect global C cycling and climate change feedbacks. Despite the influence of SOM chemistry\u2014here defined as soil organic C (SOC) and soil organic N (SON) functional groups and compounds\u2014on decomposition, uncertainty exists regarding the response of SOM chemistry to climate change and associated land use shifts. Here, we adopt a climosequence approach, using latitude along a uniform glacial till deposit at the grassland\u2013forest ecotone in central Canada as a surrogate for the effects of climate change on SOM chemistry. Additionally, we evaluate differences in SOM chemistry from paired native grassland, native trembling aspen ( Populus tremuloides ) forest, and arable soil profiles to investigate the effects of likely climate-induced land use alterations.  The combination of C and N  K -edge X-ray absorption near edge structure (XANES) with pyrolysis-field ionization mass spectrometry (Py-FIMS) techniques was used to examine SOM chemistry at atomic and molecular scales, respectively. These techniques revealed only modest differences in surface SOM chemistry related to land use and latitude. Greater variation was apparent in the vertical stratification of SOM constituents from soil depth profiles. These findings indicate that pedon-scale processes have greater control over SOM chemistry than do processes operating on landscape (e.g. land use) and regional (e.g. climate) scales. Additionally they imply that SOM chemistry is largely unresponsive to climatic change on the magnitude of the mean annual temperature (MAT) gradient under study (~\u00a00.7\u00a0\u00b0C), despite its location at the grassland\u2013forest boundary highlighting its sensitivity, and is similarly unresponsive to associated land use shifts.", "keywords": ["Vegetation", "Ecology and Evolutionary Biology", "Plant Sciences", "Agriculture", "Genetics and Genomics", "04 agricultural and veterinary sciences", "15.

However, although the impact of the use of legumes as cover crops has been broadly studied, very little is known about the effects of grain legume-based rotations on soil organic carbon (SOC) and nitrogen (SON). A cropping system experiment with three 3-year rotations with different levels of inclusion of grain legumes: GL0, GL1 and GL2 (none, one, and two grain legumes, respectively), with (CC) or without (BF, bare fallow) cover crops was established in SW France (Auzeville) under temperate climate. Durum wheat was present in all the rotations to act as an indicator of their performance. Soil organic C and SON were quantified before the beginning of the experiment and after 3 and 6 years (i.e. after one and two complete 3-yr rotations). Aboveground C and N inputs to the soil, and C and N harvest indexes and grain yield of the cash crops were also measured. Inserting grain legumes in the rotations significantly affected the amount of C and N inputs and consequently SOC and SON. After two cycles of the 3-yr rotation, the GL1 and GL2 treatments showed a greater decrease in SOC and SON when compared to GL0. However, the inclusion of cover crops in the rotations led to mitigate this loss. Durum wheat produced significantly greater grain yields in GL1 when compared to GL0, while GL2 presented intermediate values. In turn, the incorporation of cover crops did not reduce C and N harvest indexes or the grain yield of the different cash crops. We concluded that, in such conventionally-tilled grain legume-based rotations, the use of cover crops was efficient to mitigate SOC and SON losses and then increase N use efficiency at the cropping system level without reducing productivity.

In previous research, we showed that net primary production (NPP) increased by 23 \uffc2\uffb1 2% when four experimental forests were grown under atmospheric concentrations of CO             2             predicted for the latter half of this century. Because nitrogen (N) availability commonly limits forest productivity, some combination of increased N uptake from the soil and more efficient use of the N already assimilated by trees is necessary to sustain the high rates of forest NPP under free-air CO             2             enrichment (FACE). In this study, experimental evidence demonstrates that the uptake of N increased under elevated CO             2             at the Rhinelander, Duke, and Oak Ridge National Laboratory FACE sites, yet fertilization studies at the Duke and Oak Ridge National Laboratory FACE sites showed that tree growth and forest NPP were strongly limited by N availability. By contrast, nitrogen-use efficiency increased under elevated CO             2             at the POP-EUROFACE site, where fertilization studies showed that N was not limiting to tree growth. Some combination of increasing fine root production, increased rates of soil organic matter decomposition, and increased allocation of carbon (C) to mycorrhizal fungi is likely to account for greater N uptake under elevated CO             2             . Regardless of the specific mechanism, this analysis shows that the larger quantities of C entering the below-ground system under elevated CO             2             result in greater N uptake, even in N-limited ecosystems. Biogeochemical models must be reformulated to allow C transfers below ground that result in additional N uptake under elevated CO             2             .           </p>", "keywords": ["rotation poplar plantation", "0106 biological sciences", "Nitrogen", "Climate", "atmospheric carbon-dioxide", "enrichment face", "organic nitrogen", "Biological Transport", "deciduous forest", "04 agricultural and veterinary sciences", "Carbon Dioxide", "15.

Understanding the effects of grazing on nitrogen cycling in grassland ecosystems is critical for better management and for improving knowledge of the mechanisms underlying grassland degradation and can provide basic information for sustainable development in grassland ecosystems. In this study, in situ incubation in intact soil cores was used to measure seasonal changes in soil nitrogen mineralization and nitrification in the meadow steppe of the Hulunber grasslands of northeastern China. Soil plots were subjected to varying intensities of cattle grazing, and soil characteristics including several aspects of the nitrogen cycle were analysed. The findings demonstrate that soil inorganic N pools and nitrogen mineralization peaked in August and that moderate grazing intensity produced higher seasonal mean net N mineralization (Amin); net nitrogen mineralization rate (Rmin); net ammonification rate (Ramm) and net nitrification rate (Rnit). Seasonal mean net mineralization rate was increased by 6-15% in the lightly and moderately grazed plots (0.34-0.46 AU cow/ha) and by 4-5% in the heavily grazed plots (0.69-0.92 AU cow/ha). Also it was found that soil moisture was significantly positively correlated with inorganic N, Amin, Ramm and Rmin and significantly negatively correlated with Rnit, while soil temperature exhibited the opposite effect.

This study evaluated the effect of acidified biochars from pine chips (PC) and peanut hulls (PH) on NH3 losses and inorganic N and P released from surface-applied or incorporated PL. Poultry litter with or without acidified biochars was surface-applied or incorporated into the soil and incubated for 21 d. Volatilized NH3 was determined by trapping it in acid.

Acidified biochars reduced NH3 losses by 58 to 63% with surface-applied PL, and by 56 to 60% with incorporated PL. Except for PH biochar, which caused a small increase in leached NH4+-N with incorporated PL, acidified biochars had no effect on leached or KCl-extractable inorganic N and P from surface-applied or incorporated PL.

We compiled the data of  DOC fluxes in throughfall and soil profiles from 91 sites, of which the  DOC flux data at 18 sites have been published by our group. The climate  was classified into four groups [polar climate (MAT &lt; 0 \u00baC), boreal  climate (0 \u00baC &lt; MAT &lt; 6 \u00baC), temperate climate (6 \u00baC  &lt; MAT &lt; 20 \u00baC), tropical climate (20 \u00baC &lt; MAT)],  based on mean annual air temperature. The other  parameters include climatic properties [mean annual precipitation and mean  annual air temperature], plant litter properties [litterfall C input, C/N  ratio, Klason-lignin (residue after digestion with sulfuric acid; Allen et  al., 1974), lignin/N ratio, root litter production] and soil properties  [soil C stocks (O horizon and mineral soil (0-30 cm depth)), pH (water  extraction), clay content, short-range-order (amorphous) aluminum (Al),  iron (Fe) (acid ammonium oxalate extractable Al and Fe; McKeague and Day,  1966)]. The sampling and analytical methods are  concisely summarized as follows: Throughfall (canopy leaching) samples  were collected by precipitation collector, while soil solution samples  were collected using tension-free lysimeters for downward flux of water  percolating in the soil profiles. Sample solutions were filtered through a  0.45 \u00b5m filter (e.g., PTFE syringe filter) and stored at 1\u00b0C in the dark  prior to analyses. The concentrations of DOC were determined using a total  organic carbon and nitrogen analyzer (TOC-V<sub>CSH</sub>,  Shimadzu, Japan). The dissolved organic nitrogen (DON) concentrations were  calculated by subtracting dissolved inorganic nitrogen (sum of  NH<sub>4</sub><sup>+</sup> and  NO<sub>3</sub><sup>-</sup>) from TDN  concentrations (DON = TDN -  NH<sub>4</sub><sup>+</sup> -  NO<sub>3</sub><sup>-</sup>) to obtain DOC/DON  ratios in soil solution. The DOC flux at the depth of 0 cm (the bottom of  organic layers) and the bottom of B horizon (the bottom of rooting zone)  was estimated by multiplying DOC concentrations in soil solution and water  fluxes at each depth. Soil water fluxes were estimated by hydrological  models or precipitation-evapotranspiration water budgets. Annual root  production was measured by ingrowth core method, net sheet method, or  sequential sampling method and estimated to be equal to annual root litter  inputs. Proportion of DOC flux from the O horizon  relative to C input via both throughfall and litterfall was calculated by  dividing DOC flux from the O horizon by C input via both throughfall and  litterfall. DOC retention in the mineral soil was calculated as the  percentage of net decrease in DOC flux between O and B horizons relative  to DOC flux from the O horizon. The apparent turnover time (yr) of soil C  was estimated by dividing soil C stocks (Mg C ha<sup>\u20131</sup>)  by C inputs (net DOC inputs and root litter inputs into the mineral soil)  (Mg C ha<sup>\u20131</sup> yr<sup>\u20131</sup>).", "keywords": ["tropical forest", "FOS: Earth and related environmental sciences", "Soil pH", "dissolved organic carbon", "dissolved organic nitrogen"], "contacts": [{"organization": "Fujii, Kazumichi", "roles": ["creator"]}]}, "links": [{"href": "https://doi.org/10.5061/dryad.k6djh9wdx"}, {"rel": "self", "type": "application/geo+json", "title": "10.5061/dryad.k6djh9wdx", "name": "item", "description": "10.5061/dryad.k6djh9wdx", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items/10.5061/dryad.k6djh9wdx"}, {"rel": "collection", "type": "application/json", "title": "Collection", "name": "collection", "description": "Collection", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main"}], "time": {"date": "2024-02-19T00:00:00Z"}}, {"id": "10261/211171", "type": "Feature", "geometry": null, "properties": {"updated": "2026-06-24T16:25:29Z", "type": "Dataset", "title": "Basic data underlying research in manuscrip \"Variation of soil organic carbon, stable isotopes, and soil quality indicators across an erosion\u2013deposition catena in a historical Spanish olive orchard\"", "description": "Open AccessSpanish Ministry of Economy and Competitiveness (grant no.

Here, we assessed N<sub>2</sub> fixation in two dominant mosses in boreal forests (<italic>Pleurozium schreberi</italic> and <italic>Sphagnum capillifolium</italic>) in response to different levels of N, simulating realistic (up to 4 kg N ha<sup>\u22121</sup> yr<sup>\u22121</sup>) and extreme N deposition rates in pristine ecosystems (up to 20 kg N ha<sup>\u22121</sup> yr<sup>\u22121</sup>) of IN (NH<sub>4</sub>NO<sub>3</sub>) and ON (alanine and urea). We also assessed if N<sub>2</sub> fixation can recover from the N additions. In the realistic scenario, N<sub>2</sub> fixation was inhibited by increasing NH<sub>4</sub>NO<sub>3</sub> additions in <italic>P. schreberi</italic> but not in <italic>S. capillifolium</italic>, and alanine and urea stimulated N<sub>2</sub> fixation in both moss species. In contrast, in the extreme N additions, increasing N inputs inhibited N<sub>2</sub> fixation in both moss species and all N forms. Nitrogen fixation was more sensitive to N inputs in <italic>P. schreberi</italic> than in <italic>S. capillifolium</italic> and was higher in the recovery phase after the realistic compared to the extreme N additions. These results demonstrate that N<sub>2</sub> fixation in mosses is less sensitive to organic than inorganic N inputs and highlight the importance of considering different N forms and species-specific responses when estimating the impact of N inputs on ecosystem functions such as moss-associated N<sub>2</sub> fixation.</p>", "keywords": ["0301 basic medicine", "0303 health sciences", "03 medical and health sciences", "Sphagnum", "Nitrogen fixation", "Nitrogen pollution", "Organic nitrogen", "15.
