Elevated CO2 may alter microbial activities that regulate soil N availability by changing the amount or composition of organic substrates produced by roots. Our objective was to determine the potential for elevated CO2 to change N availability in an experimental plant-soil system by affecting the acquisition of root-derived C by soil microbes. We grew Populus tremuloides (trembling aspen) cuttings for 2 years under two levels of atmospheric CO2 (36.7 and 71.5 Pa) and at two levels of soil N (210 and 970 \u00b5g N g-1). Ambient and twice-ambient CO2 concentrations were applied using open-top chambers, and soil N availability was manipulated by mixing soils differing in organic N content. From June to October of the second growing season, we measured midday rates of soil respiration. In August, we pulse-labeled plants with 14CO2 and measured soil 14CO2 respiration and the 14C contents of plants, soils, and microorganisms after a 6-day chase period. In conjunction with the August radio-labeling and again in October, we used 15N pool dilution techniques to measure in situ rates of gross N mineralization, N immobilization by microbes, and plant N uptake. At both levels of soil N availability, elevated CO2 significantly increased whole-plant and root biomass, and marginally increased whole-plant N capital. Significant increases in soil respiration were closely linked to increases in root biomass under elevated CO2. CO2 enrichment had no significant effect on the allometric distribution of biomass or 14C among plant components, total 14C allocation belowground, or cumulative (6-day) 14CO2 soil respiration. Elevated CO2 significantly increased microbial 14C contents, indicating greater availability of microbial substrates derived from roots. The near doubling of microbial 14C contents at elevated CO2 was a relatively small quantitative change in the belowground C cycle of our experimental system, but represents an ecologically significant effect on the dynamics of microbial growth. Rates of plant N uptake during both 6-day periods in August and October were significantly greater at elevated CO2, and were closely related to fine-root biomass. Gross N mineralization was not affected by elevated CO2. Despite significantly greater rates of N immobilization under elevated CO2, standing pools of microbial N were not affected by elevated CO2, suggesting that N was cycling through microbes more rapidly. Our results contained elements of both positive and negative feedback hypotheses, and may be most relevant to young, aggrading ecosystems, where soil resources are not yet fully exploited by plant roots. If the turnover of microbial N increases, higher rates of N immobilization may not decrease N availability to plants under elevated CO2.", "keywords": ["0106 biological sciences", "root-: biomass-", "Ecology and Evolutionary Biology", "nitrogen-fixation", "Environmental-Sciences)", "01 natural sciences", "nitrogen", "biomass-", "nitrogen-cycle", "nitrogen-", "Microorganisms-", "carbon-14", "124-38-9: CARBON DIOXIDE", "C Cycle", "Spermatophytes-", "Spermatophyta-", "Key Words Atmospheric CO2", "Cellular and Developmental Biology", "Populus Tremuloides Michx", "2.

Muller and F.H. Bormann posited their 'vernal dam' hypothesis, stating that spring-ephemeral herbs in deciduous forests serve as a temporary sink for N when overstory trees are dormant, and then release this N later, in the summer, when the trees are active. This hypothesis has gained wide acceptance, yet two of its critical assumptions have never been experimentally tested: (1) that N taken up by spring ephemerals would otherwise be lost from the ecosystem, and (2) that N from senesced ephemeral tissues contributes to increased rates of summertime N mineralization. To test these assumptions, I quantified patterns of N cycling and loss from a set of paired plots, half of which served as controls and from half of which all spring-ephemeral plants were removed. There were no significant differences in NO3- leaching between plots with and without spring ephemeral vegetation. These results are consistent with the relatively low rates of N uptake by the dominant spring ephemeral, Allium tricoccum, and its apparent preference for NH4+, which is far less mobile in soil than NO3-. In addition, based on sequential sampling, I found that soil microorganisms took up 8 times as much N during the spring than did spring-ephemeral herbs (microbial uptake=3.19 vs. plant uptake=0.41 g N m-2), suggesting that microbial immobilization of N is the dominant sink for N during this season. Removal of spring ephemeral vegetation also had no effect on summertime rates of net N mineralization. Furthermore, the addition of spring ephemeral litter to soil+forest floor microcosms did not significantly increase rates of N mineralization in a laboratory incubation. Instead, this experiment demonstrated the overwhelming influence of forest floor litter in controlling the release of mineral N from these soils. Overall, neither assumption of the vernal dam hypothesis holds true in this ecosystem, where patterns of N cycling and loss appear to be dominated by microbial decomposition of forest floor material and soil organic matter.", "keywords": ["0106 biological sciences", "NO3\u2013 Leaching", "N Immobilization", "Science", "Ecology and Evolutionary Biology", "Key Words Vernal Dam", "Natural Resources and Environment", "Molecular", "04 agricultural and veterinary sciences", "15.

The experimental design was a randomized-block design with factorial combinations of high or low soil N and ambient (34 Pa) or elevated (69 Pa) CO2 in five blocks.

Because of the importance of fine roots to the belowground C cycle, we monitored fine-root biomass and associated C fluxes in regenerating stands of trembling aspen, and mixed stands of trembling aspen and paper birch at FACTS-II, the Aspen FACE project in Rhinelander, Wisconsin. Free-air CO2 enrichment (FACE) was used to elevate concentrations of CO2 (average enrichment concentration 535\u00a0\u00b5l l-1) and O3 (53\u00a0nl l-1) in developing forest stands in 1998 and 1999. Soil respiration, soil pCO2, and dissolved organic carbon in soil solution (DOC) were monitored biweekly. Soil respiration was measured with a portable infrared gas analyzer. Soil pCO2 and DOC samples were collected from soil gas wells and tension lysimeters, respectively, at depths of 15, 30, and 125\u00a0cm. Fine-root biomass averaged 263\u00a0g m-2 in control plots and increased 96% under elevated CO2. The increased root biomass was accompanied by a 39% increase in soil respiration and a 27% increase in soil pCO2. Both soil respiration and pCO2 exhibited a strong seasonal signal, which was positively correlated with soil temperature. DOC concentrations in soil solution averaged ~12\u00a0mg l-1 in surface horizons, declined with depth, and were little affected by the treatments. A simplified belowground C budget for the site indicated that native soil organic matter still dominated the system, and that soil respiration was by far the largest flux. Ozone decreased the above responses to elevated CO2, but effects were rarely statistically significant. We conclude that regenerating stands of northern hardwoods have the potential for substantially greater C input to soil due to greater fine-root production under elevated CO2. Greater fine-root biomass will be accompanied by greater soil C efflux as soil respiration, but leaching losses of C will probably be unaffected.", "keywords": ["0106 biological sciences", "Ecology and Evolutionary Biology", "Aspen-FACE-project", "root-", "USA-", "pollutants-", "Environmental-Sciences)", "tropospheric-ozone", "forest-productivity", "01 natural sciences", "biomass-", "northern-forests", "124-38-9: CARBON DIOXIDE", "soil-carbon-flux", "terrestrial-ecosystems", "populus-tremuloides", "Cellular and Developmental Biology", "soil-carbon", "7440-44-0: CARBON", "carbon-", "fine-root", "Bioenergetics- (Biochemistry-and-Molecular-Biophysics)", "Natural Resources and Environment", "04 agricultural and veterinary sciences", "GLOBAL-ECOLOGY", "North-America", "Nearctic-region)", "Rhinelander- (Wisconsin-", "carbon-sequestration", "atmosphere-", "biomass-production", "dissolved-organic-carbon [DOC-]", "Science", "respiration-", "carbon-dioxide-enrichment", "forest-plantations", "carbon-dioxide", "carbon-storage", "fine-root-biomass", "belowground-biomass", "United-States-Wisconsin-Rhinelander", "carbon-cycle", "Health Sciences", "ozone-", "soil-respiration", "air-pollution", "global-change", "atmospheric-carbon-dioxide", "biomass", "Molecular", "15.

There is increasing concern over the potential for increasing nitrogen (N) inputs to affect biocrusts. This is of special concern in Mediterranean Basin drylands that face the threat of increased N inputs however, the effect on biocrusts remains poorly studied. We evaluated the potential effects of increased N inputs on biocrust structure and functioning in surrounding Mediterranean shrublands in the seventh year of a N-manipulation field experiment. We tracked the N-driven changes in biotope (changes in bare soil and in the non-legume and the legume occupation areas, and the percentage of radiation intercepted by plant canopies), evaluated biocrust functional traits (based on pigments) and measured biocrust functioning in terms of C and N cycling, soil fertility (macro and micronutrients) and biodiversity, and integrated these multiple soil functions simultaneously (i.e. soil multifunctionality) Biocrust pigment concentration was significantly influenced by both plant legacy and N input. Biocrust pigments revealed a clear functional shift from: i) biocrusts dominated by photosynthetically inactive cyanobacteria that fix N and are mostly committed to photoprotection at the expense of N-containing pigments under low N inputs; into ii) biocrusts more evenly composed of prokaryotes and eukaryotes, which are more photosynthetically active, but less committed to photoprotection and N fixation under exposure to increased N inputs. The N-driven functional and structural changes in biocrusts resulted in trade-offs in biocrust functioning and processes (only N fixation was affected) and an overall improvement in biocrust multifunctionality. By itself, biocrust pigment evenness accounted for ~50% of the observed variation in biocrust multifunctionality. The biocrust pigment functional approach we adopted to study the effects of increased N inputs from patchy developed anthropogenic landscapes provides novel and critical knowledge of biocrusts community and functioning, which may be used as a tool in biodiversity conservation strategies, ecosystem functions and ecological modelling.", "keywords": ["0301 basic medicine", "2.

We examined how long this legacy of disturbance constrains forest carbon (C) storage rates by quantifying C pools and fluxes after harvest and fire in a mixed deciduous forest chronosequence in northern lower Michigan, USA. Study plots ranged in age from 6 to 68 years and were created following experimental clear\uffe2\uff80\uff90cut harvesting and fire disturbance. Annual C storage was estimated biometrically from measurements of wood, leaf, fine root, and woody debris mass, mass losses to herbivory, soil C content, and soil respiration. Maximum annual C storage in stands that were disturbed by harvest and fire twice was 26% less than a reference stand receiving the same disturbance only once. The mechanism for this reduction in annual C storage was a long\uffe2\uff80\uff90lasting decrease in site quality that endured over the 62\uffe2\uff80\uff90year timeframe examined.

There is increasing concern over the potential for increasing nitrogen (N) inputs to affect biocrusts. This is of special concern in Mediterranean Basin drylands that face the threat of increased N inputs however, the effect on biocrusts remains poorly studied. We evaluated the potential effects of increased N inputs on biocrust structure and functioning in surrounding Mediterranean shrublands in the seventh year of a N-manipulation field experiment. We tracked the N-driven changes in biotope (changes in bare soil and in the non-legume and the legume occupation areas, and the percentage of radiation intercepted by plant canopies), evaluated biocrust functional traits (based on pigments) and measured biocrust functioning in terms of C and N cycling, soil fertility (macro and micronutrients) and biodiversity, and integrated these multiple soil functions simultaneously (i.e. soil multifunctionality) Biocrust pigment concentration was significantly influenced by both plant legacy and N input. Biocrust pigments revealed a clear functional shift from: i) biocrusts dominated by photosynthetically inactive cyanobacteria that fix N and are mostly committed to photoprotection at the expense of N-containing pigments under low N inputs; into ii) biocrusts more evenly composed of prokaryotes and eukaryotes, which are more photosynthetically active, but less committed to photoprotection and N fixation under exposure to increased N inputs. The N-driven functional and structural changes in biocrusts resulted in trade-offs in biocrust functioning and processes (only N fixation was affected) and an overall improvement in biocrust multifunctionality. By itself, biocrust pigment evenness accounted for ~50% of the observed variation in biocrust multifunctionality. The biocrust pigment functional approach we adopted to study the effects of increased N inputs from patchy developed anthropogenic landscapes provides novel and critical knowledge of biocrusts community and functioning, which may be used as a tool in biodiversity conservation strategies, ecosystem functions and ecological modelling.", "keywords": ["0301 basic medicine", "2.

(In Press). Northern temperate pastures  exhibit divergent plant community responses to management and disturbance  legacies identified through a producer survey. <em>Applied  Vegetation Science</em>. <b>1.\u00a0 Study  location</b> We surveyed 102 pastures during 2012 (n=44) and 2013 (n=58)  between May 24 and July 6, distributed across agricultural lands within 80  km of Edmonton, Alberta, Canada.\u00a0 About half the pastures were in the  Central Parkland (n=50), with the remainder in the Dry Mixedwood (n=50)  and Central Mixedwood (n=2) subregions.\u00a0A large and well-distributed  sample size ensured wide variation in soil textures, seeded and non-seeded  vegetation, and management actions. Pastures were selected using a  stratified random approach, separated by at least 800 m. Pastures were  identified through consultation with municipal county staff, then driving  roadsides to confirm suitable fields visually. Pastures had to accommodate  a 260 m long transect (minimum of 4 ha) with buffer zones from wetlands  (30 m), forests and fence lines (10 m), with larger pastures given  preference.\u00a0Acquisition of sites was constrained by landowners\u2019  willingness to grant permission to their land, although refusals were  uncommon (n &lt; 10). A privacy agreement with landowners prohibits us  from releasing the locations of pastures.  <strong>2. Producer management and disturbance  history</strong> \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 Pasture management  and disturbance history were acquired for all 102 pastures through a  retrospective, in-person interview.\u00a0Interviews were approved by the  University of Alberta\u2019s Research Ethics Board (ID: Pro0030842). Interviews  identified historical and current land-use practices and natural  disturbances potentially influencing soil and vegetation. Managers were  initially asked about ownership and whether the pasture had been  previously cultivated. If cultivated, managers estimated when it was  planted (grassland age) and how (seeding history was described in Pyle,  Hall, &amp; Bork, 2018); cultivation status could also be classified  as unknown (attributed to land-turnover or rented pasture). Recent  management actions were summarized, including grazing history (grazing  system, timing of grazing, number of animals, type of livestock,  supplemental feeding with hay), mechanical treatments (aerated, harrowed,  or swathed/mowed), nutrient addition (fertilizer or manure), or herbicide  application. Livestock stocking rates [in animal-unit-months per ha (AUM  ha<sup>-1</sup>)] were calculated for pastures (n=80) where  adequate information on grazing activities was obtained (see Pyle, Hall,  &amp; Bork, 2018), where one AUM is the forage required to support a  mature cow (with or without a calf) for one month. Other natural  disturbances capable of influencing vegetation, such as a known history of  recent fire, were recorded. All management actions and disturbance factors  are described in Appendix S1 (<em>Applied Vegetation  Science</em> manuscript). <strong>3.  Plant cover, ground cover, and soil properties</strong>  \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0Following the interview, a grassland assessment was  conducted. To begin sampling, a random point was located from which a 260  m long \u2018W-transect\u2019 was laid out (Thomas, 1985). Plant composition and  ground cover were assessed at nine equidistant locations using a 0.25  m<sup>2</sup> quadrat. Foliar cover was estimated for each  plant species, with trace species recorded as 0.1%. Plants were identified  (Moss &amp; Packer, 1983) and nomenclature updated using VASCAN  (Brouillet et al., 2018). Plant species were later grouped into major  cover components by origin (total native, total introduced) and growth  form [forbs, graminoids (grasses, sedges, rushes)], as well as functional  groups such as introduced grasses (seeded or widely naturalized),  introduced legumes (seeded or widely naturalized), introduced ruderal  forbs (agronomic weeds), noxious weeds [defined by the <i>Weed  Control Act </i>(Province of Alberta, 2010)], native perennial  graminoids, native perennial forbs, native ruderal forbs, and native woody  plants. These functional groups are related to rangeland health, which  evaluates key forages, along with unpalatable and disturbance-induced  plants. For each pasture, plant community richness, diversity (effective  number of species), and Pielou\u2019s evenness were summarized for inclusion in  multivariate analyses. At all locations where cover was observed, the area of  litter and exposed mineral soil on the ground surface were estimated, and  litter depth was measured at five random locations within the 0.25  m<sup>2 </sup>frame. Mineral soil was sampled to a depth of 15  cm at ten random locations. During preparation of soil cores (Pyle, Hall,  &amp; Bork, 2019), charcoal layers in the top 15 cm of mineral soil  were often found, indicating fire occurrence in the pasture\u2019s history and  not reported by managers. For each grassland, soil properties including %  total carbon (C), % total nitrogen (N), carbon to nitrogen ratio (C:N),  organic matter (OM), pH, electrical conductivity (EC), and texture (%  clay, % sand, % silt) were measured. Procedures and specific responses are  summarized elsewhere (Pyle, Hall, &amp; Bork, 2019).  <strong>4. Rangeland health</strong>  \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0Rangeland health was assessed using the <i>Tame  Pasture Assessment Form </i>developed by Alberta Environment and  Parks (Adams et al., 2010; resources available at https://www.alberta.ca/range-health.aspx). In brief, this process evaluated grasslands based on six criteria, including: (1) vegetation composition and forage cover (tame or modified-tame), (2) the status of vegetation as either desirable (i.e., tall, productive forages) or non-desirable (non-palatable) species in tame pasture, (3) hydrologic function and nutrient cycling (abundance of litter), (4) site stability (exposed mineral soil and evidence of erosion), (5) noxious weeds, and (6) encroachment by woody plants (scoring is summarized in Pyle, Hall, &amp; Bork, 2018). In total, 60% of the health score arises from vegetation attributes, 25% from hydrologic function, and 15% from site stability (Adams et al., 2010). <strong>5. Literature Cited</strong> Adams, B.

Introduced, invasive plants can alter local soil chemistry and  microbial communities, but the underlying mechanisms and extent of these  changes are largely unknown. Based on characteristics associated with  invasiveness in plants, it was hypothesized that introduced species that  produce large amounts of litter with distinctive secondary compounds can  a) alter the chemistry of both extractable and bulk carbon in the soil, b)  shift microbial communities towards microbes better able to metabolize the  compounds in the litter, and c) cause soil carbon chemistry and microbial  communities to shift to relatively uniform, novel states at multiple  sites. 2. Composition of phenolics in senescent tissues (leaves and roots)  of Polygonum cuspidatum was compared to the composition of extractable  phenolics and non-extractable bulk organic carbon in soils under and  adjacent to large, long-established stands of P. cuspidatum at four sites  in the eastern U.S. Rates of degradation of phenolics, activities of  enzymes associated with the breakdown of phenolics, and shifts in  microbial community composition were also measured at the sites. 3. Soils  under P. cuspidatum stands contained twice as much phenolics as adjacent  soils, but the composition of phenolics differed greatly between soils  under stands and senescent tissues of P. cuspidatum. Flavonoids and  proanthocyanidins constituted &gt;90% of the identified phenolics in  P. cuspidatum tissues, whereas monophenolic compounds accounted for  &gt; 90% of the phenolics in soils under stands. Soils under and  adjacent to stands also exhibited distinctive compositions of relatively  persistent bulk organic carbon; composition differed less between soils  under stands at different sites than between soils under and adjacent to  stands at the same site. 4. Soils under P. cuspidatum had 2.8 times  greater abundance of fungi than soils adjacent to stands, and fungal  markers showed clear separation of soils under and adjacent to P.  cuspidatum. However, the potential activity of enzymes that degrade  polyphenols was lower in soils under stands. Exogenously applied  chemically complex polyphenols persisted in both P. cuspidatum invaded and  adjacent non-invaded soils, whereas less complex compounds rapidly  disappeared from both soils. 5. Synthesis. Results suggest that  interactions between plant inputs, abiotic reactions, and biotic  transformations may create and maintain new states in invaded soils that  are chemically and biologically less diverse. In the case of polyphenol  rich, fast growing invasive species, these interactions may alter the  composition of bulk soil organic matter that has slower turnover rates,  resulting in legacy effects. Restoration could thus require, not just  removal of the species, but also post-removal interventions such as soil  amendments.", "keywords": ["Flavonoids", "Peroxidases", "Mass spectrometry", "tannins", "Fallopia japonica", "Japanese knotweed", "Reynoutria japonica", "Polyphenols", "home-field advantage", "Legacy effect", "15.

Invasive plant species are key drivers of global environmental changes  leading to the disruption of ecosystems they invade. Many invasive species  engage in novel niche construction through plant-soil feedbacks  facilitated by the input of secondary compounds, which help their further  spread and survival. These compounds can persist in soil even after the  removal of the invader thus creating a legacy effect that inhibits the  return of native flora and fauna. Thus, formulating active intervention  strategies that can reverse niche construction is critical for the  restoration of these invaded ecosystems. 2. We hypothesized that the  management practices that can reverse the soil carbon and nutrient cycling  in invaded ecosystems can facilitate the rapid restoration of the invaded  sites. We predicted that adding soil C amendments such as activated carbon  and biochar can alter the microbial functional activity and nutrient  cycling leading to the restoration of invaded habitats. We tested this  hypothesis in an old-field in Massachusetts that has been invaded by  Japanese knotweed (Polygonum cuspidatum) for &gt;20 years. 3. After  two years of treatment application, the activated carbon and biochar  amended plots had 80% more biomass of the prairie species than the control  plots. The C amendments also altered soil nutrient cycling and fungal  biomass and enzyme activity compared to the control plots. The nitrate  content of C amended plots was 5 times higher than the non-amended control  plots indicating an increased nitrogen mineralization in C amended plots  potentially due to the sorption of phenolic compounds by activated carbon  and biochar that makes them unavailable. This was further supported by the  increased phenol oxidase activity which might have been less inhibited by  tannins and led to increased organic matter decomposition. 4. Synthesis  and conclusions: Our results thus reveal the potential of soil C  amendments in reversing niche construction and legacy effects of  polyphenol-rich invasive species and indicate that biochar could be a more  economically feasible alternative to activated carbon in restoring invaded  ecosystems. Our results also emphasize that understanding the mechanism  through which invasive species engage in niche construction is vital in  formulating suitable knowledge-based restoration practices for invaded  ecosystems.", "keywords": ["2.

The climate consists of warm,  wet summers and dry, cold winters. Mean annual precipitation is ~835 mm  with ~75% of rainfall occurring during the growing season (April \u2013  September). Annual precipitation for the two years of the study was 811 mm  in 2018 and 971 mm in 2019, with ~64% and 75% of the precipitation  occurring during the growing season in each year, respectively (Figure  S1). For this study, we utilized a large-scale, well-replicated drought  experiment (the Extreme Drought in Grasslands Experiment, EDGE) that was  established in 2013 in an annually burned and ungrazed native tallgrass  prairie site. The site was located on a flat, level upland with relatively  deep (~1 m or more), well-drained clay loam soils characterized as silty  clay Mollisols. <em>Experimental  Design</em> The EDGE experiment imposed drought  in two ways from 2014-2017 using large rainfall exclusion shelters (n = 20  total), each 6 x 6 m in size and hydrologically isolated to a depth of ~1  m (see Griffin-Nolan et al. 2019 for more details). For the chronic  drought treatment, 10 shelters were covered with strips of clear  corrugated polycarbonate spaced so as to reduce each growing season  rainfall event by 66% (April \u2013 September). For the intense drought  treatment, the remaining 10 shelters were completely covered with panels  of clear corrugated polycarbonate to exclude all rainfall events with no  precipitation entering the intense treatment plots until a similar amount  of total growing season rainfall was excluded as the chronic treatment  (May \u2013 July), resulting in a shorter, but more intense reduction in  rainfall. \u00a0Both drought treatments resulted in a ~45% reduction in annual  rainfall. Shelter roofs were put in place in May each year for both  drought treatments. Roofs were removed each year in early Sept for the  chronic treatment, while they were removed after a similar amount of  rainfall was reduced in the intense treatment; this was typically reached  after ~ 2 months of the panels being installed (typically May \u2013 July). The  control treatment plots were unsheltered (n = 10), but still  hydrologically isolated and received ambient rainfall throughout the  growing season. The three treatments were arranged in blocks, each  containing a replicate of each treatment, for a total of 10 blocks (n = 30  plots). To assess post-drought legacy effects on C and  N cycling, we removed the shelters after the four years of drought  treatments and allowed ambient rainfall to fall onto all of the treatments  in 2018 and 2019 (the first two years following drought). This allowed us  to measure whether legacy effects were present and whether recovery  occurred. <em>Soil Sampling\u00a0  </em> In 2018 and 2019, we collected soils  monthly throughout the growing season (late May, early July, and  mid-August) to measure soil C and N cycling. We homogenized four random  soil core samples (15 cm depth x 5.7 cm diameter) collected from each  \u201cdestructive plot\u201d as detailed in Griffin-Nolan et al. (2019). The samples  were immediately placed on ice and sieved to 2 mm within 24 hours. A  subsample of these soils was kept fresh and unfrozen for laboratory-based  microbial respiration measurements. The rest of the soil was transferred  to a -20\u00b0C freezer until further analysis for all other non-in situ  measurements. All analyses on frozen soils were performed within a year  after collection. <em>Soil  Moisture</em> We measured soil moisture in both  the field and the lab to assess if soil moisture exhibited any legacies as  a mechanism for the reponses we measured. We used a hand-held TDR to  measure in-situ soil moisture to a depth of 15 cm at each time of soil  sampling. We additionally dried field-collected soil (the same soil used  to measure nutrients) for 48 hours at 60\u00b0C to calculate moisture and soil  wet soil/dry conversion factors for subsequent nutrient and enzyme  analyses. <em>Soil Nutrient Fluxes and Pools  </em> To characterize legacy effects of drought  on C and N cycling, we measured in situ belowground respiration, lab-based  soil microbial respiration, extractable inorganic N (ammonium and  nitrate), extractable total dissolved organic C and N, in situ net N  mineralization, and total soil organic C and N concentrations to measure  main components of C and N cycling. Belowground  respiration was measured in situ using a Li-Cor 8100 infrared gas sampler  (Lincoln, Nebraska). Two PVC collars were installed in each plot to a 6 cm  depth and left in the field for the duration of the growing season. All  biomass and living plants were removed from the collars at the beginning  of the season and prior to every measurement. We then used a Li-Cor 8100  infrared gas sampler to measure CO<sub>2</sub> flux from the  soil over a 60 second interval. Measurements were taken midday and during  sunny and non-windy conditions to ensure uniform conditions for each  measurement. Measurements were taken monthly in 2018 and weekly in 2019.  More detailed methods can be found in Slette et al. (2021).  To measure soil microbial respiration in the lab, we placed 30  grams of sieved, fresh soil (the fresh unfrozen subsample; extracted from  the field &lt; 24 hours prior) from each plot in a sealable mason-jar  (8 cm wide x 15 cm deep). We kept the soils at the same moisture from the  field by sealing the soils in plastic bags and sealing the jars  immediately after adding the soil. We measured microbial respiration once  within 24 hours of extracting soil by opening the jars to allow  re-equilibration with ambient CO<sub>2</sub> and then  re-sealing the jars for 1-2 hours to measure accumulated headspace  CO<sub>2</sub>. Respiration was then quantified as detailed in  Zeglin and Myrold (2013). To measure extractable  inorganic N, we extracted ammonium and nitrate from the previously frozen  soil subset collected monthly. We shook 11 g of thawed field-moist soil  with 1M KCl for 1 hour and then filtered the samples using Whatman filters  (grade 42 \u2013 2.5 mm filter). We then froze the extracts in a -20\u00b0C freezer  until analysis. Extractable N was expressed on a per gram soil dry weight  basis. To measure net N mineralization, a twelve-centimeter deep PVC tube  (3.81 cm diameter) with the top two centimeters above ground was pounded  into the ground next to the initial soil cores taken on the same date. The  PVC tubes were capped, with holes in the aboveground portion of the tubes  for gas exchange, and left in place for ~30 days. Cores were retrieved at  the end of the incubation interval, then sieved within 24 hours, frozen in  a -20\u00b0C freezer, and later extracted with 1 M KCl using the methods above.  We used an Alpkem analyzer to measure extractable ammonium and nitrate on  all KCl extracts (Saskatoon, SK). Net N mineralization was measured as the  difference between extractable inorganic N in the initial and final cores.  This was then divided by the days the cores were left in the field to  calculate a daily rate. To measure total dissolved  organic C (DOC) and N (DON), we extracted 20 g field-moist subsamples of  the previously frozen soil with 100 mL of 0.5M  K<sub>2</sub>SO<sub>4</sub>. We shook the soils  for four hours and filtered the samples using Whatman 42 filters, \u00a0then  froze the extracts in a -20\u00b0C freezer. We used a Schimadzu TOC-L analyzer  (Kyoto, Japan) to measure DOC and DON. To measure total  C and N, we oven dried the soils at 60\u00b0C for several days until the soil  was deplete of any moisture. The soils were then ground and analyzed for  total C and N in a LECO TruSpec CN combustion analyzer (St. Joseph, MI) at  the KSU Soil Testing Lab. <em>Extracellular  Enzyme Activity</em> We measured the potential  extracellular enzyme activities of several microbially-produced enzymes as  an index of nutrient limitation. We measured C-cleaving enzymes:  a-Glucosidase (AG), b-Glucosidase (BG), b-D-cellulosidase (CB), and  b-Xylosidase (XYL); N-cleaving enzymes: N-acetyl glucosaminidase (NAG) and  leucyl aminopeptidase (LAP); and phosphorus-cleaving enzymes: phosphatase  (PHOS). Substrates for each enzyme were attached to a highly fluorescent  cleavage product. The substrates for AG, BG, CB, XYL, NAG, and PHOS were  attached to 4-methylumbelliferyl (MUB), and the substrate for LAP was  attached to 7-amino-4-methylcoumarin (MUC). We added a Tris buffer  adjusted to a pH of 8 to our soils to create a soil slurry and shook our  samples for 40 minutes. We then added our samples to a 96 well-plate and  added substrates to our soil slurries with two replicates per sample.  Additionally, we created MUB and MUC standard curves for each individual  soil. To simulate standard soil conditions, the plates were incubated for  3 hours in the dark at 25\u00b0C. Fluorescence was measured using a multiplate  reader (Tecan Infinite M200 plate reader, Switzerland) with a 365-nm  excitation and 460-nm emission filters. A quench control was used. More  detailed methods can be found in Bell et al. (2013) and Trivedi et al.  (2016). We summed the C enzymes for total C enzyme activity and the N  enzymes for total N enzyme activity (Bell et al., 2013; Dove et al.,  2020). <em>Statistical  Analyses</em> To compare treatments across each  year\u2019s growing season, we calculated confidence intervals and standard  error using mixed models that accounted for repeated measures over the  growing season (monthly sampling). We conducted separate statistical  analyses for 2018 and 2019 due to the different climatic conditions of the  two years. Further discussion of why the two years were split can be found  in results 3.1. Our mixed model contained both fixed and random effects.  Time and treatment were both fixed variables with an interaction term to  account for the repeated measures aspect of this experiment (lme4  package). As mentioned previously, our experiment had a blocked design.  Blocks were treated as a random variable except for some models where we  had to treat block as a fixed variable. In our 2018 enzyme analysis, we  ran into a problem of overfitting due to block variance being estimated as  zero in the model. To correct this overfitting, we treated block as a  fixed effect and used this model to draw conclusions. Additionally, we  applied a natural log conversion to all enzyme activity data due to  unequal variances detected from the residual vs. fitted plot of the  original non-transformed models. For the belowground respiration models,  we included soil moisture as a covariate, since soil moisture has strong  effects on belowground respiration. Further, we calculated correlation  coefficients for soil moisture and belowground respiration in both years.  For all statistical analyses, we utilized R statistical software (R Core  Team, 2013) and used several packages including lme4, lmerTest, pbkrtest,  emmeans, and GGally. We also used R to create the graphics for this paper  using ggplot2 and Hmisc to create 95% confidence intervals for each  graphic.", "keywords": ["2. Zero hunger", "13.
