Effects of Soil Warming on Bacterial Degradation of Carbohydrates at Harvard Forest 2011

As Earth’s climate warms, soil carbon pools and the microbes that process them may change, altering the way in which carbon is recycled in soil. We used bacterial cultivation to evaluate the hypothesis that experimentally raising soil temperatures by 5°C for 20 years increased the potential for temperate forest soil microbial communities to degrade carbohydrates. A greater proportion of the 295 bacteria from 6 phyla (10 classes, 14 orders, and 34 families) isolated from heated plots in the 20-year experiment were able to depolymerize cellulose and xylan than bacterial isolates from control soils. These findings indicate that the enrichment of bacteria capable of degrading carbohydrates could be important for accelerated carbon cycling in a warmer world. Data for the isolates from the Harvard Forest culturing project is archived at https://osf.io/ahb2v/.

Microbial and soil moisture impacts of compost amendments and rainfall pulses in a degraded dryland soil, Arizona, 2021-2023

Compost, an organic soil amendment, has been proposed to increase soil carbon storage and water-holding capacity in drylands, and this management strategy may be particularly impactful in degraded drylands with low soil organic content. Compost additions and rainfall variability may interact to affect soil moisture, which is an important catalyst for soil microbial activity. This dataset is from a study that investigated how variable compost application amounts and simulated rainfall pulses affect soil moisture, microbial activity, and carbon content in a laboratory incubation study. Soils were amended with different amounts of compost (0, 0.35, and 0.70 g cm -2) and water pulses (5, 10, and 15 mm) in a full-factorial design. Each treatment received the same cumulative amount of water throughout the incubation, but pulses occurred at different frequencies (every 5, 10, and 15 days). Soil moisture content and microbial respiration were measured daily. Soil carbon content was measured at the end of the experiment.

Vis-NIR Soil Spectral Library of the Hungarian Soil Degradation Observation System

Since soil spectroscopy is considered to be a fast, simple, accurate and non-destructive analytical method, its application can be integrated with wet analysis as an alternative. Therefore, development of national-level soil spectral libraries containing information about all soil types represented in a country is continuously increasing to serve as a basis for calibrated predictive models capable of assessing physical and chemical parameters of soils at multiple spatial scales. In this article, we present a database containing laboratory and visible-near infrared spectral data of legacy soil samples from the Hungarian Soil Degradation Observation System (HSDOS). The published data set includes the following parameters measured in 5,490 soil samples: pHKCl, soil organic matter (SOM), calcium carbonate (CaCO3), total salt content (TSC), total nitrogen (Ntotal), soluble phosphorus (P2O5-AL), soluble potassium (K2O-AL), plasticity index according to Hungarian standard (PLI), soil profile depth and reflectance data between 350 and 2,500 nm wavelength. The presented database can be a complement for further soil related research on continental, national or regional scales to support sustainable soil management. Uploaded CSV file contains variables for general information, soil parameters and reflectance data of spectral bands between 350-2,500 nm. Details about variables can be found in Table 1. <table> <tbody> <tr> <td> Column name </td> <td> Description </td> <td> Method </td> <td> Unit </td> </tr> <tr> <td> SAMPLE_TDR_ID </td> <td> Original TDR IDs </td> <td> - </td> <td> - </td> </tr> <tr> <td> SAMPLING_DATE </td> <td> Date of sampling </td> <td> - </td> <td> YYYY-MM-DD </td> </tr> <tr> <td> NORTHING_EOV </td> <td> Northing coordinate of sampling area centroids </td> <td> - </td> <td> m </td> </tr> <tr> <td> EASTING_EOV </td> <td> Easting coordinate of sampling area centroids </td> <td> - </td> <td> m </td> </tr> <tr> <td> LON_WGS84 </td> <td> Longitude of sampling area centroids </td> <td> - </td> <td> ° </td> </tr> <tr> <td> LAT_WGS84 </td> <td> Latitude of sampling area centroids </td> <td> - </td> <td> ° </td> </tr> <tr> <td> pH_KCl </td> <td> pH </td> <td> Potentiometer (MSZ–08 0206-2: 1978)40 </td> <td> - </td> </tr> <tr> <td> SOM </td> <td> Soil organic matter </td> <td> E4/E6 ratio41,42 (MSZ–08-0452:1980)43 </td> <td> % </td> </tr> <tr> <td> CaCO3 </td> <td> Calcium carbonate </td> <td> Scheibler type calcimeter (MSZ–08 0206-2:1978)40 </td> <td> % </td> </tr> <tr> <td> TSC </td> <td> Total salt content </td> <td> EC-TDS electrode (MSZ–08-0206-2:1978)40 </td> <td> w/w % </td> </tr> <tr> <td> TN </td> <td> Total nitrogen </td> <td> Kjeldahl method44 (ISO 11261:1995)45 </td> <td> mg kg-1 </td> </tr> <tr> <td> P2O5_AL </td> <td> Soluble phosphorus </td> <td> AL extract atomic adsorption spectrophotometry (MSZ 20135:1999)46 </td> <td> mg kg-1 </td> </tr> <tr> <td> K2O_AL </td> <td> Soluble potassium </td> <td> AL extract, flame photometer (MSZ 20135:1999)46 </td> <td> mg kg-1 </td> </tr> <tr> <td> PLI </td> <td> Plasticity index according to Hungarian standard </td> <td> Yarn test of Arany (MSZ–08 0205-2:1978)47 </td> <td> - </td> </tr> <tr> <td> PROFILE_LEVEL </td> <td> Soil profile depth level </td> <td> - </td> <td> - </td> </tr> <tr> <td> SPC350:2500 </td> <td> spectral reflectance in the range of 350 and 2500 nm </td> <td> ASD FieldSpec 4 spectroradiometer </td> <td> - </td> </tr> </tbody> </table> Table 1.

Size-dependent effects of oxo-degradable plastic contamination on soil quality and Zea mays L. performance

Agricultural plastic mulch films represent a significant source of microplastic contamination in soils, raising concerns about soil health and food security. Oxo-degradable plastics (ODPs) have emerged as a potentially more eco-friendly alternative to conventional plastic mulch films, however, uncertainty remains around the degradation rate of ODPs in soil and their impacts on soil quality and crop health. Using a controlled mesocosm experiment, we evaluated the behaviour and impact of different concentrations of oxo-biodegradable macro- (>10 mm) or micro-plastic (<5 mm) (0.01, 0.1, 1, and 10% w/w) on the performance of Zea mays L. grown in an agricultural soil over a 6-week period. Contrary to expectation, no major fragmentation or degradation of ODP was observed during the experimental period, however, FTIR revealed the formation of carbonyl groups indicative of oxidation. Overall, our results showed that typical levels of plastic contamination (0.01% w/w) had very little effect on soil physicochemical properties, microbial activity or plant performance. However, higher levels of plastic contamination resulted in significant changes in soil pH, EC, NO3-, bulk density, and soil moisture. At extreme plastic loading rates (10% Can you write w/w), both micro- and macro-sized ODPs caused significant reductions in plant height and foliar chlorophyll content, with microplastic treatments showing consistently greater effects than macroplastics. None of the plastic loading rates had an effect on shoot and root biomass or soil NH4+ and P concentrations or microbial community structure in comparison to the unamended controls. Our findings indicate that at realistic field concentrations, ODPs are likely to have little effect on agroecosystem functioning but that they may persist in soil for long periods of time leading to their progressive accumulation in agricultural soils if used over repeated cropping cycles. Further research is needed to evaluate the longer-term impacts of ODPs on soil quality and crop health under field conditions.

Comparison of polyphenol degrading enzyme activities between forest types and soil horizons from 2003 to 2004

In the southern Appalachians Rhododendron maximum thickets suppress conifer and hardwood regeneration. While there has been research on the effects of R. maximum on physical and chemical environment, the functioning of R. maximum ericoid mycorrhizas has been unexplored. The litter of ericaceous plants tends to be rich in phenolic compounds. These compounds can form recalcitrant complexes with various forms of organic N, and may be responsible for lowering decomposition and N mineralization rates. While polyphenol-organic N complexes are highly recalcitrant, some fungi, particularly ericoid mycorrhizal fungi, have the ability to access this sequestered N. Since the litter of ericaceous plants is rich in phenolic compounds and ericoid mycorrhizal fungi are equipped to degrade phenolic compounds, polyphenol-organic N complexing may represent an N cycling strategy that prevents non-ericaceous plants from accessing sources of organic N. We propose to examine the activities of polyphenol degrading enzymes in the soil of R. maximum thickets and neighboring hardwood forests.

Rare soil microbial taxa regulate the negative effects of land degradation drivers on soil organic matter decomposition

1. Land degradation drivers, including loss in vegetation and eutrophication, are expected to impact soil biodiversity and functions in drylands world-wide. Soils contain both common and rare microbial taxa that drive multiple soil functions. Yet, little is known about how these microbial taxa influence the impacts of land degradation drivers on ecosystem functions. Obtaining this information is essential to determine whether rare taxa need to be protected, or if protecting only common taxa would be enough to sustain and protect ecosystem functions and services. 2. Here, we conducted an experiment to investigate the effects of N-enrichment and vegetation loss (plant removal), which are two major land degradation drivers in semi-arid grasslands, on the diversities of common and rare soil bacterial and fungal taxa and soil function [soil organic matter (SOM) decomposition] in a long-term experiment. 3. Six years after N-enrichment and vegetation loss, we found that N-enrichment decreased the alpha diversities of common and rare soil bacteria and rare soil fungi, while vegetation loss only decreased the alpha diversity of rare soil fungi. Both N-enrichment and vegetation loss altered the community composition of common and rare bacteria and fungi, except for the lack of response of common soil fungi to the vegetation loss. Moreover, both structural equation modelling and variation partitioning analyses show that land degradation drivers reduce SOM decomposition, and these were also indirectly associated with changes in the diversity of rare microbial taxa, especially that of bacteria. 4. Synthesis and applications. Collectively, this work shows that land degradation can have negative impacts on soil biodiversity and functions, and the rare microbial taxa indirectly regulate the impacts of land degradation on ecosystem functioning. These results indicate that the rare microbial taxa can be used as one of the ecological indicators for identifying land degradation in the semi-arid grasslands. These findings are essential to understand the future impacts of desertification and land degradation on rare microbial taxa–function relationships in global drylands.

Data for: How do harvesting methods applied in continuous-cover forestry and rotation forest management impact soil carbon storage and degradability in boreal Scots pine forests?

Forest management affects soil carbon (C) storage through forest composition, microclimate and litter inputs. How two major forest management systems, continuous-cover forestry (CCF) and clear-cut-based rotation forest management (RFM), differ in their impact on soil C in boreal forests is still poorly understood, however. We compared their effects on soil organic carbon (SOC) storage and quality in boreal Scots pine (Pinus sylvestris L.) dominated forests in eastern Finland. We tested the hypotheses that (1) colder microclimates and continuous litter inputs will lead to higher SOC stocks in CCF plots than in clear-cuts and (2) the more labile litter in clear-cuts with varying ground vegetation will enhance SOC decomposition rates. We sampled uncut mature forests, clear-cuts, retention-cuts and gap-cuts, in which we analysed SOC concentrations and calculated the stocks. We measured stand characteristics such as diameter-at-breast height, basal area, dominant tree height, and understorey species coverage of the various treatments and modelled the above- and belowground litter inputs based on these parameters. We used laboratory incubation and sequential fractionation of SOC to assess its degradability under standardized conditions. To estimate the decomposition rate in the various environments we incubated cellulose bags in situ. We assessed the impact of microclimate on SOC decomposition, using data from soil-temperature and soil-moisture field measurements. We quantified the microbial biomass C pool, using chloroform fumigation extraction to gain insight on the impact of forest management practice on soil microbes. The SOC concentrations and SOC stocks did not differ significantly between the treatments, despite the presence of a warmer microclimate and lower litter inputs in the clear-cut plots. However, we found differences in the quality of the SOC. Soils in clear-cut sites showed lower proportions of labile SOC compounds than did the other treatments. As hypothesized, the decomposition rates were elevated in clear-cuts, but were equally as high within the canopy gaps on gap-cut stands. Our work highlights that forest management affects the quality, degradability, long-term accumulation and storage of SOC. We conclude that the accumulation of labile compounds in uncut forests and retention-cuts, combined with the decreased decomposition rates, indicate a higher potential for future C accumulation in the soil than in clear-cuts.
