Soil respiration is the second largest flux of carbon (C) in these ecosystems, and the objective of this study was to understand how soil respiration responded to the experimental treatments as these fast-growing stands of pure aspen and birch + aspen approached maximum leaf area. Rates of soil respiration were typically lowest in the elevated O3 treatment. Elevated CO2 significantly stimulated soil respiration (8-26%) compared to the control treatment in both community types over all three growing seasons. In years 6-7 of the experiment, the greatest rates of soil respiration occurred in the interaction treatment (CO2 + O3), and rates of soil respiration were 15-25% greater in this treatment than in the elevated CO2 treatment, depending on year and community type. Two of the treatments, elevated CO2 and elevated CO2 + O3, were fumigated with 13C-depleted CO2, and in these two treatments we used standard isotope mixing models to understand the proportions of new and old C in soil respiration. During the peak of the growing season, C fixed since the initiation of the experiment in 1998 (new C) accounted for 60-80% of total soil respiration. The isotope measurements independently confirmed that more new C was respired from the interaction treatment compared to the elevated CO2 treatment. A period of low soil moisture late in the 2003 growing season resulted in soil respiration with an isotopic signature 4-6 per thousand enriched in 13C compared to sample dates when the percentage soil moisture was higher. In 2004, an extended period of low soil moisture during August and early September, punctuated by a significant rainfall event, resulted in soil respiration that was temporarily 4-6 per thousand more depleted in 13C. Up to 50% of the Earth's forests will see elevated concentrations of both CO2 and O3 in the coming decades and these interacting atmospheric trace gases stimulated soil respiration in this study.", "keywords": ["0106 biological sciences", "Science", "Ecology and Evolutionary Biology", "Cell Respiration", "Acer", "Carbon Cycling", "Plant Roots", "01 natural sciences", "Trees", "Soil", "Ozone", "Stable Isotope", "Air Pollution", "Health Sciences", "\u03b4 13 C", "Global Change", "Cellular and Developmental Biology", "Betula", "Ecosystem", "Soil Microbiology", "Carbon Isotopes", "Atmosphere", "Natural Resources and Environment", "Molecular", "Carbon Dioxide", "15.

All the three earthworm species combined caused larger impacts on most variables measured than any single earthworm species. These included loss of O horizon mass, decreased thickness of the O horizon and increased thickness of the A horizon, and higher availability of N and P. The latter finding differs from field reports where nutrients were less available after invasion, and probably represents an initial transient increase in nutrient supply as earthworms consume and incorporate the O horizon into the A horizon. Earthworms also increased mortality of plants and decreased total mesocosm plant biomass, but here the impact of all the three earthworm species was no greater than that of L. terrestris and/or L. rubellus alone.

Some of the more well-studied effects include the biogeochemical feedbacks to the climate system that can either increase or decrease the atmospheric load of greenhouse gases such as carbon dioxide and nitrous oxide. Less well-studied are the effects of climate change on the linkages between soil and plant processes. Here, we report the effects of soil warming on these linkages observed in a large field manipulation of a deciduous forest in southern New England, USA, where soil was continuously warmed 5\u00b0C above ambient for 7 years. Over this period, we have observed significant changes to the nitrogen cycle that have the potential to affect tree species composition in the long term. Since the start of the experiment, we have documented a 45% average annual increase in net nitrogen mineralization and a three-fold increase in nitrification such that in years 5 through 7, 25% of the nitrogen mineralized is then nitrified. The warming-induced increase of available nitrogen resulted in increases in the foliar nitrogen content and the relative growth rate of trees in the warmed area. Acer rubrum (red maple) trees have responded the most after 7 years of warming, with the greatest increases in both foliar nitrogen content and relative growth rates. Our study suggests that considering species-specific responses to increases in nitrogen availability and changes in nitrogen form is important in predicting future forest composition and feedbacks to the climate system.", "keywords": ["Ecosystem ecology - Original Paper", "0106 biological sciences", "550", "Nitrogen", "Climate Change", "Population Dynamics", "Acer", "04 agricultural and veterinary sciences", "Nitrogen Cycle", "15.

It has been hypothesized that declines of inorganic nitrogen (N) and increases of organic N influence changes in EMF taxa over forest development. In a post-wildfire chronosequence of six jack pine (Pinus banksiana) stands ranging in age from 5 to 56 years, we investigated EMF community composition and compared shifts in taxa with detailed soluble inorganic and organic N data. Taxa were identified by internal transcribed spacer rDNA sequencing, and changes in community composition evaluated with non-metric multi-dimensional scaling (NMDS). Dissimilarities in the community data were tested for correlations with N variables. We observed a successional shift along NMDS axis 1 from such taxa as Suillus brevipes and Thelephora terrestris in sites age 5 and 11 to species of Cortinarius and Russula, among others, in the four older sites. This change was positively correlated with soluble organic N (SON) (r(2) = 0.902, P = 0.033) and free amino-acid N (r(2) = 0.945, P = 0.021), but not inorganic N. Overall, our results show a successional shift of EMF communities occurring between stand initiation and canopy closure without a change in species of the dominant plant-host, and associated with SON and free amino-acid N in soil. It is uncertain whether EMF taxa are responding to these organic N forms directly, affecting their availability, or are ultimately responding to changes in other site variables, such as belowground productivity.", "keywords": ["0106 biological sciences", "Mycorrhizae", "DNA", " Ribosomal Spacer", "Population Dynamics", "0401 agriculture", " forestry", " and fisheries", "Biodiversity", "04 agricultural and veterinary sciences", "Nitrogen Cycle", "15.

A small amount of 15N tracer was applied at the start of the second growing season, and its distribution among Sphagnum, vascular plant species, and peat was determined at the end of the third growing season. The 15N tracer was also applied to additional plots at the untreated field site to check for initial distribution. One week after addition, 79% of the total amount of 15N retrieved was found in the living Sphagnum layer and less than 10% had been captured by vascular plants. Fifteen months later, 63% of the total amount of 15N retrieved was still present in the living Sphagnum layer at ambient N deposition. Increased N deposition significantly reduced the proportion of 15N in Sphagnum and increased the amount of 15N in vascular plants. Deep-rooting vascular plant species were significantly more 15N enriched, suggesting that at higher atmospheric inputs N penetrates deeper into the peat.

By utilizing these techniques, a field study was carried out to analyze the effect of tillage implement and plastic sizes on plastic displacement, to understand the fate of macroplastics in arable land. Results indicated that the displacement of macroplastics did not depend upon plastic sizes but did depend upon the tillage implement used.

We examined the combined effects of elevated CO2 concentration ([CO2]) and defoliation on growth and physiology of sugar maple (Acer saccharum Marsh.) and trembling aspen (Populus tremuloides Michx.). Seedlings were planted in the ground in eight open-top chambers. Four chambers were ventilated with CO2-enriched air (ambient + 283 micromol mol-1) and four chambers were supplied with ambient air. After 6 weeks of growth, half of the leaf area was removed on a subset of seedlings of each species in each CO2 treatment. We monitored subsequent biomass gain and allocation, along with leaf gas exchange and chemistry. Defoliation did not significantly affect final seedling biomass in either species or CO2 treatment. Growth recovery following defoliation was associated with increased allocation to leaf mass in maple and a slight enhancement of mean photosynthesis in aspen. Elevated [CO2] did not significantly affect aspen growth, and the observed stimulation of maple growth was significant only in mid-season. Correspondingly, simulated responses of whole-tree photosynthesis to elevated [CO2] were constrained by a decrease in photosynthetic capacity in maple, and were partially offset by reductions in specific leaf area and biomass allocation to foliage in aspen. There was a significant interaction between [CO2] and defoliation on only a few of the measured traits. Thus, the data do not support the hypothesis that atmospheric CO2 enrichment will substantially alter tree responses to folivory. However, our findings do provide further indication that regeneration-stage growth rates of certain temperate tree species may respond only moderately to a near doubling of atmospheric [CO2].", "keywords": ["defoliation-", "0106 biological sciences", "Ecophysiology", "Quaking aspen", "biomass-allocation", "growth-response", "Growth", "Environmental-Sciences)", "01 natural sciences", "plant-composition", "Trees", "biomass-", "Spermatophyta-", "Biomass", "Photosynthesis", "plant-physiology", "defoliation", "Angiospermae-", "leaf-area", "GLOBAL-ECOLOGY", "seedling-growth", "source-sink-relations", "Populus-tremuloides", "gas-exchange", "Populus", "broadleaves-", "deciduous-tree", "forest-trees", "atmosphere-", "trees-", "biomass-production", "Acer saccharum", "Nitrogen", "Carbohydrates", "Acer", "carbon-dioxide-enrichment", "photosynthesis-", "growth-", "species-differences", "seedlings-", "wisconsin-", "Populus tremuloides", "photosynthesis", "Climatic changes", "Carbon Dioxide", "15.

Since snow insulates soil, a decreased snow pack can increase the frequency of soil freezing, which has been shown to have important biogeochemical implications. One of the most notable effects of soil freezing is increased inorganic nitrogen losses from soil during the following growing season. Decreased nitrogen retention is thought to be due to reduced root uptake, but has not yet been measured directly. We conducted a 2\uffe2\uff80\uff90year snow\uffe2\uff80\uff90removal experiment at Hubbard Brook Experimental Forest in New Hampshire, USA to determine the effects of soil freezing on root uptake and leaching of inorganic nitrogen simultaneously. Snow removal significantly increased the depth of maximal soil frost by 37.2 and 39.5\uffc2\uffa0cm in the first and second winters, respectively (P\uffc2\uffa0&lt;\uffc2\uffa00.001 in 2008/2009 and 2009/2010).

These observed reductions in root nitrogen uptake coincided with significant increases in soil solution concentrations of ammonium in the Oa horizon (P\uffc2\uffa0=\uffc2\uffa00.001 for 2009 and 2010) and nitrate in the B horizon (P\uffc2\uffa0&lt;\uffc2\uffa00.001 and P\uffc2\uffa0=\uffc2\uffa00.003 for 2009 and 2010, respectively).

Meanwhile, the internal transcribed spacer (ITS) sequencing by Illumina Miseq platform at each taxonomic level demonstrated that the toxicological effect of oil pollutants obviously influenced the fungal diversity and community structure in soil. Moreover, it was found that the presence of three genera (Cephalotheca, Lecanicillium, and Septoriella) appeared in aged oil sludge-contaminated soil. And oil pollutants promoted the growth of certain genera in Ascomycota (70.83%) and Basidiomycota (10.78%), such as Venturia, Alternaria, and Piloderma. Nevertheless, the growth of Mortierella (9.16%), Emericella (6.02%), and Bjerkandera (0.00%) was intensively limited.

Because N deposition commonly increases foliar N concentrations, it is thought that this increase in forest growth is a consequence of enhanced leaf-level photosynthesis. However, tests of this mechanism have been infrequent, and increases in photosynthesis have not been consistently observed in mature forests subject to chronic N deposition. In four mature northern hardwood forests in the north-central United States, chronic N additions (30 kg N ha(-1) yr(-1) as NaNO3 for 14 years) have increased aboveground growth but have not affected canopy leaf biomass or leaf area index. In order to understand the mechanism behind the increases in growth, we hypothesized that the NO3(-) additions increased foliar N concentrations and leaf-level photosynthesis in the dominant species in these forests (sugar maple, Acer saccharum). The NO3(-) additions significantly increased foliar N. However, there was no significant difference between the ambient and +NO3(-) treatments in two seasons (2006-2007) of instantaneous measurements of photosynthesis from either canopy towers or excised branches. In measurements on excised branches, photosynthetic nitrogen use efficiency (micromol CO2 s(-1) g(-1) N) was significantly decreased (-13%) by NO3(-) additions. Furthermore, we found no consistent NO3(-) effect across all sites in either current foliage or leaf litter collected annually throughout the study (1993-2007) and analyzed for delta 13C and delta 18O, isotopes that can be used together to integrate changes in photosynthesis over time. We observed a small but significant NO3(-) effect on the average area and mass of individual leaves from the excised branches, but these differences varied by site and were countered by changes in leaf number. These photosynthesis and leaf area data together suggest that NO3(-) additions have not stimulated photosynthesis. There is no evidence that nutrient deficiencies have developed at these sites, so unlike other studies of photosynthesis in N-saturated forests, we cannot attribute the lack of a stimulation of photosynthesis to nutrient limitations. Rather than increases in C assimilation, the observed increases in aboveground growth at our study sites are more likely due to shifts in C allocation.", "keywords": ["0106 biological sciences", "Carbon Isotopes", "Michigan", "Nitrates", "Time Factors", "Nitrogen", "Acer", "04 agricultural and veterinary sciences", "Oxygen Isotopes", "15.

However,  how differences in litter quality affect SOC decomposition and formation  remains unclear over the full litter decomposition trajectory.\u00a0  We followed the in-situ complete decomposition of added 13C-labelled high-  (low C:N) and low-quality (high C:N) leaf-litter and its effect on  particulate (POM) and mineral-associated (MAOM) organic matter fractions  over two years in a natural subtropical forest. We found that during early  stages of decomposition, low-quality litter inputs decreased SOC via a  positive priming effect (i.e., new C inputs favored decomposition of  native SOC), but these SOC losses were offset by SOC gains observed via a  negative priming effect during decomposition of high-quality litter. In  contrast, this pattern reversed during late stages of decomposition\u2014SOC  losses via a positive priming effect induced by high-quality litter were  offset by SOC gains via a negative priming effect induced by low-quality  litter. Over the full decomposition of litter, both high- and low-quality  litter stimulated microbial breakdown of SOC tied to POM, but also  replenished more persistent SOC that associated with soil minerals (MAOM).  Altogether, we observed that low-quality litter formed twice as much new  SOC as high-quality litter (24% vs. 12% of added litter-C). We extend the  notion of the priming effect\u00a0from primarily a negative role  promoting losses of native SOC, to a functional role that can replenish  persistent SOC. Synthesis. Our measurements raise the possibility that, in  species-rich forests, high- and low-quality litter decomposition play  opposite but dynamically complementary roles in renewing POM\u2014both by  inducing its decomposition and formation\u2014while exclusively favoring MAOM  formation, which can help explain how differences in litter quality favor  SOC accumulation and persistence.

In this study, we used the  15N-tracer method to investigate both the short-term (1 week to 3 months)  and long-term (1 to 3 years) fates of deposited NH4+ or NO3- by following  the recovery of the 15N in different ecosystem compartments in a larch  plantation forest and a mixed forest located in northeastern China. The  results showed similar total ecosystem retention for deposited NH4+ and  NO3-, but their distribution within the ecosystems (plants vs soil)  differed distinctly particularly in the short-term, with higher 5NO3-  recoveries in plants (while lower recoveries in organic layer) than found  for 15NH4+. The different short-term fate was likely related to the higher  mobility of 15NO3- than 15NH4+ in soils instead of plant uptake  preferences for NO3- over NH4+. In the long-term, differences between N  forms became less prevalent but higher recoveries in trees (particularly  in the larch forest) of\u00a015NO3- than 15NH4+ tracer persisted,  suggesting that incoming NO3- may contribute more to plant biomass  increment and forest carbon sequestration than incoming NH4+. Differences  between the two forests in recoveries were largely driven by a higher 15N  recovery in the organic layer (both N forms) and in trees (for 5NO3-) in  the larch forest compared to the mixed forest. This was due to a more  abundant organic layer and possibly higher tree N demand in the larch  forest than in the mixed forest. Leachate 15N loss was minor (&lt;1%  of the added 15N) for both N forms and in both forests. Total 15N recovery  averaged 78% in the short-term and decreased to 55% in the long-term but  with increasing amount of 15N label (re)-redistributed into slow turn-over  pools (e.g., trees and mineral soil). The different retention dynamics of  deposited NH4+ and NO3- may have implications in environmental policy  related to the anthropogenic emissions of the two N forms.", "keywords": ["15N tracer", "N retention and redistribution", "FOS: Earth and related environmental sciences", "15.

Within PROMISCES technologies to remediate PFAS and iPMT(s) in several environmental media have been developed. This deliverable D2.4 'Planning & design tool for drinking water treatment for PFAS & industrial chemicals' reports on a tool developed to improve planning and design of drinking water treatment trains for PFAS and iPMT, especially focussing on the adsorption onto granular activated carbon (GAC), alternative adsorbents and removal using ion exchange (IX) resins. Despite several previous studies on PFAS and iPMT removal during drinking water treatment, there are still information gaps on how to best implement suitable treatment trains in practice. The design of a suitable treatment train will depend on the effectiveness of the adsorbent for the removal of various mixtures of chemicals, different background water qualities as well as treatment goals. Modelling tools can be used to predict treatment performance under varying conditions and are especially helpful to improve the informative value of pilot tests. For example, potential changes in influent concentration, background water quality, flow rate, adsorbent bed height not covered in pilot tests can be simulated using models. Whereas GAC adsorption is already well studied, competitive adsorption of dissolved organic matter (DOM) and PFAS and iPMT is less understood and design tools are lacking. The developed drinking water treatment and design tool (DWTDT) is applicable for fixed-bed adsorber design in water treatment trains. It allows to predict operation times until exhaustion of fixed-bed adsorbers using GAC or ion exchange resins. This includes a rough estimation of ideal breakthrough using equilibrium isotherm data as main input data as well as prediction of the dynamic breakthrough using additional input parameters describing internal and external mass transfer.  Dynamic breakthrough prediction is based on the pore surface diffusion model (PSDM) developed by the United States Environmental Protection Agency (EPA) and extended with the so-called tracer model (TRM), allowing to map the breakthrough of DOM and its competing effects on PFAS and iPMT removal. Both, the original model by the EPA as well as the DWTDT were developed using the programming language python. A user interface was built for the DWTDT to make it more user-friendly. The model was tested with experimental input data from the laboratory tests and validated with pilot plant data gained in the PROMISCES project. The DWTDT is publicly available on GitHub. This will allow users to simulate simultaneous DOM, PFAS and iPMT breakthrough in drinking water treatment trains using adsorbents or ion exchange resins provided the necessary input data including single solute isotherm data, external mass transfer coefficients, internal diffusion coefficients, adsorption parameters for DOM background are known or can be estimated.", "keywords": ["Deliverable", "Adsorption Analysis", "iPMT", "PFAS", "Tracer Model", "Pore Surface Diffusion Model", "H2020 PROMISCES", "Adsorption", "Drinking water treatment processes", "Ideal Adsorbed Solution Theory"]}, "links": [{"href": "https://doi.org/10.5281/zenodo.13982527"}, {"rel": "self", "type": "application/geo+json", "title": "10.5281/zenodo.13982527", "name": "item", "description": "10.5281/zenodo.13982527", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items/10.5281/zenodo.13982527"}, {"rel": "collection", "type": "application/json", "title": "Collection", "name": "collection", "description": "Collection", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main"}], "time": {"date": "2024-10-23T00:00:00Z"}}, {"id": "10.5424/sjar/2006044-212", "type": "Feature", "geometry": null, "properties": {"updated": "2026-09-22T16:21:22Z", "type": "Journal Article", "created": "2013-11-21", "description": "<p>Soil degradation is the result of interactions involving the soil itself, human activity, climate, relief, and vegetation.

The aim of this study was to determine the behaviour of a number of soil physical variables and total organic carbon content, as well as the root activity and yield of crops grown in rotation (soybean in 1998/1999 and maize in 1999/2000) under direct sowing (DS) and conventional tillage (CT) conditions. Root activity was assessed using an isotopic methodology involving the uptake of 32P. The root activity of the soybean crop, which grew under normal rainfall conditions, was greater under CT conditions. That of the maize crop, which grew when rainfall was well below normal, was greater under DS conditions. Bulk density was higher and total porosity lower in the upper 0.10 m of the soil in the DS plots. Conventional tillage led to lower penetration resistance values in the upper layers of the soil profile. No differences in soil total organic carbon were found between the two tillage systems. The soil water content of the upper soil layers was higher under DS. The yield of the soybean crop under CT was 57% higher than under DS. The yield of maize was affected by water deficiency; higher yields were obtained with DS than with CT.</p>", "keywords": ["Glycine max", "Argentina", "Rendimiento de cultivos", "Soil fertility", "Zea mays", "Tracer techniques", "Glycine max; Zea mays; Crop rotation; Conventional tillage; Zero tillage; Soil chemicophysical properties; Soil fertility; Tracer techniques; Crop yield; Argentina", "Glycine max; Zea mays; Rotaci\u00f3n de cultivos; Labranza convencional; Cero-labranza; Propiedades f\u00edsico - qu\u00edmicas suelo; Fertilidad del suelo; T\u00e9cnicas de trazadores; Rendimiento de cultivos; Argentina", "Crop rotation", "Labranza convencional", "Crop yield", "Fertilidad del suelo", "2.

Our understanding of macroplastics (> 5\u00a0mm) occurrence and behavior has remained comparatively elusive, mainly due to a lack of a tracing mechanism. This study set up a methodology to trace macroplastic displacement, which combined magnetic iron oxide-tagged soil and macroplastic pieces tagged by an adhesive passive radiofrequency identification transponder. By utilizing these techniques, a field study was carried out to analyze the effect of tillage implement and plastic sizes on plastic displacement, to understand the fate of macroplastics in arable land. Results indicated that the displacement of macroplastics did not depend upon plastic sizes but did depend upon the tillage implement used. The mean macroplastics displacement per tillage pass was 0.36\u00a0\u00b1\u00a00.25\u00a0m with non-inversion chisel tillage and 0.15\u00a0\u00b1\u00a00.13\u00a0m with inversion disk tillage, which was similar to bulk soil displacement. However, only inversion disk tillage caused fragmentation (41\u00a0%) of macroplastics and generated microplastics (< 5\u00a0mm). In contrast, both tillage implements drove to similar burial of surface macroplastics into the tilled layer (74\u00a0% on average). These results highlight that tillage is a major process for macroplastics fate in arable soils, being one of the first studies to investigate it.", "keywords": ["2. Zero hunger", "13.
