1. The soil carbon saturation controls phosphate sorption and mobility in organically amended Ferralsols.
1. 土壤碳饱和度控制着有机改良铁铝土中磷酸盐的吸附和迁移性PMID:日期:2026-09Phosphorus (P) fertilizer efficiency in highly weathered soils is constrained by phosphate sorption on iron (Fe) and aluminum (Al) oxides. Integrated soil fertility management promotes the combined use of P fertilizers and organic amendments (OAs), but the mechanisms underlying OA-P interactions remain unclear. This study evaluated how OA dose, OA quality, and time affect P mobility, assessed through phosphate sorption and diffusion from a fertilizer granule. Three Ferralsols were incubated with compost, farmyard manure (FYM), or straw at four doses (0-4 % w/w) in a full factorial design. Phosphate sorption strength (K) was quantified after 1 and 49 days of incubation and related to the soil's degree of carbon saturation (DCS), an operational metric that is proportional to the molar ratio of organic C to the reactive Fe and Al oxides. Across all soils and treatments, K decreased with increasing DCS (R = 0.66) at 49 days after amendment, consistent with increasing competition of organic anions with phosphate for sorption sites. In contrast, the short-term (1-day) effects of amendments on K were primarily related to soil pH. A diffusion experiment using Ferralsol samples from a field trial with three years of FYM application showed wider diffusion zones around fertilizer granules in FYM-amended than in control soils. Together, these findings suggest that OA-induced improvements in P fertilizer use efficiency observed in field trials are related to competition effects and that the effects of OA dose and quality can be predicted with a mechanistic model.

2. Soil microbial diversity: A key factor in pathogen suppression and inoculant performance.
PMID:日期:2025-08Soil microbial diversity plays a crucial role in plant health, influencing pathogen suppression and biocontrol efficacy. This study investigated how soil microbial diversity modulates interactions between the pathogen and the biocontrol bacterium in the wheat rhizosphere. Using a dilution-to-extinction method, we established five soil microbial diversity levels: natural soil, dilutions at 10, 10, 10, and fully autoclaved soil. This gradient allowed us to evaluate disease severity, plant growth, and rhizosphere microbiome shifts. Inoculation with significantly reduced disease severity caused by , particularly in low-diversity soils, emphasizing the effectiveness of in these simplified environments where microbial competition is reduced. Despite higher pathogen abundance in low-diversity soils, effectively mitigated disease severity, likely through direct antagonistic activity. Alpha diversity indices confirmed a reduction in microbial diversity across the gradient, while beta diversity analyses revealed distinct shifts among treatments. Although , and were significantly enriched in natural soils with inoculation of the , statistically significant disease suppression was not observed under these higher-diversity conditions. On the other hand, in low-diverse soils (autoclaved soil), where disease is suppressed with inoculation, showed a significant enrichment when compared with the treatment inoculated only with the pathogen, suggesting that this bacterial taxon can play a role in disease suppression along with the inoculant. These findings underscore the critical role of the soil microbial diversity in shaping the success of biocontrol interventions.

3. Biocrusts alter the effects of long-term warming on soil respiration in a dryland ecosystem.
PMID:日期:2025-07Climate warming is expected to have contrasting impacts on soil respiration in dryland ecosystems, with responses ranging from positive to negative across short-, mid-, and long-term timescales. However, the long-term (>10 yr) effects of warming and their underlying mechanisms remain understudied in biocrust-dominated dryland ecosystems. In this study, we investigated the effects of 10-13 years of experimental warming on soil respiration and its underlying regulatory mechanisms at microsites with contrasting biocrust cover in a dryland ecosystem in southeastern Spain. We also examined how long-term warming and biocrust cover influenced the accumulation rate of soil organic carbon (SOC) in the surface layer (0-1 cm). Our results showed that initial and mid-term reductions in soil respiration induced by warming were transient at microsites with low biocrust cover, where respiration rates eventually returned to control levels. In contrast, the suppressive effect of warming on soil respiration persisted over the long term at microsites with high biocrust cover. At low biocrust cover microsites, soil respiration dynamics were primarily regulated by changes in SOC stocks and the activity of carbon-degrading enzymes such as β-glucosidase and β-D-cellobiosidase. Conversely, at high biocrust cover microsites, the long-term response of soil respiration appeared to be more closely associated with shifts in biocrust cover rather than enzymatic activity. Notably, SOC accumulation rates were not significantly affected by either long-term warming or biocrust cover. Overall, our findings underscore the value of long-term experimental studies for capturing delayed or persistent ecosystem responses and reducing uncertainties in projections of soil respiration and carbon-climate feedbacks under global warming.

4. The soil structural stability determined by the QuantiSlakeTest: Linkage with soil porosity, water-stable aggregate fractions and soil chemical properties.
4. 通过QuantiSlakeTest确定的土壤结构稳定性：与土壤孔隙度、水稳性团聚体分数和土壤化学性质的联系PMID:日期:2025-05Recently, the QuantiSlakeTest (QST) was developed which records mass loss or gain of intact soil samples during submergence, but it is yet unclear how slaking relates quantitatively to soil structure. This study was set up to determine if the QST can be a quick and cost-effective alternative to established structure tests and can be linked to soil porosity, determined by the soil water retention curve, or to the water-stable aggregate (WSA, >250 µm) fraction obtained by wet sieving. This was performed in a comparative study with 22 soils collected in arable and pasture land with contrasting properties. The mass loss due to aggregate breakdown in the QST was smaller as soil organic carbon (SOC) content increased (r = 0.59), while SOC correlated weaker with the WSA fraction (r = 0.45) or with relative meso + macroporosity (> 30 µm; r = 0.53). The WSA correlated strongly to oxalate extractable Fe (Fe) in the soil (r = 0.63), conforming to earlier studies, but no such trend was found for Quantislake parameters, indicating that the QST captures a different aspect of soil structure than the wet sieving. The mass loss in the Quantislake decreased with increasing relative meso + macroporosity (r = 0.68), suggesting that soil resistance to aggregate breakdown is higher in soils with a large fraction of large pores than in soils with smaller average pore sizes. In a subset of 10 soils, root mass within each Kopecky ring was recorded. It showed that the QST and relative microporosity strongly correlated with the root mass in the sample (r = 0.77 and 0.71, respectively), showing the importance of roots on soil structure. The Quantislake parameters have a much larger variability among sampling replicates (CV = 75---100 %) than the parameters of the two other methods. However, the Quantislake parameters differed much more among soils, leading to similar statistical power as wet sieving and the water retention curves. It is concluded that the QST is a useful additional index of soil structure in undisturbed soils. It even outperforms the wet sieving method to indicate mesoporosity and is thus better suited for studying, e.g., preferential flow.

5. Inorganic carbon is overlooked in global soil carbon research: A bibliometric analysis.
PMID:日期:2024-03Soils are a major player in the global carbon (C) cycle and climate change by functioning as a sink or a source of atmospheric carbon dioxide (CO). The largest terrestrial C reservoir in soils comprises two main pools: organic (SOC) and inorganic C (SIC), each having distinct fates and functions but with a large disparity in global research attention. This study quantified global soil C research trends and the proportional focus on SOC and SIC pools based on a bibliometric analysis and raise the importance of SIC pools fully underrepresented in research, applications, and modeling. Studies on soil C pools started in 1905 and has produced over 47,000 publications (>1.7 million citations). Although the global C stocks down to 2 m depth are nearly the same for SOC and SIC, the research has dominantly examined SOC (>96 % of publications and citations) with a minimal share on SIC (<4%). Approximately 40 % of the soil C research was related to climate change. Despite poor coverage and publications, the climate change-related research impact (citations per document) of SIC studies was higher than that of SOC. Mineral associated organic carbon, machine learning, soil health, and biochar were the recent top trend topics for SOC research (2020-2023), whereas digital soil mapping, soil properties, soil acidification, and calcite were recent top trend topics for SIC. SOC research was contributed by 151 countries compared to 88 for SIC. As assessed by publications, soil C research was mainly concentrated in a few countries, with only 9 countries accounting for 70 % of the research. China and the USA were the major producers (45 %), collaborators (37 %), and funders of soil C research. SIC is a long-lived soil C pool with a turnover rate (leaching and recrystallization) of more than 1000 years in natural ecosystems, but intensive agricultural practices have accelerated SIC losses, making SIC an important player in global C cycle and climate change. The lack of attention and investment towards SIC research could jeopardize the ongoing efforts to mitigate climate change impacts to meet the 1.5-2.0 °C targets under the Paris Climate Agreement of 2015. This bibliographic study calls to expand the research focus on SIC and including SIC fluxes in C budgets and models, without which the representation of the global C cycle is incomplete.

6. Understanding the influence of soil development on contaminant reactivity along a fluvial chronosequence in the Oregon Coast Range.
PMID:日期:2024-01-25Weathering processes are recognized as drivers of soil and water resource sustainability, but how pedogenesis stage impacts contaminant reactivity and mobility in soils has been minimally investigated. The primary goal of this study was to quantify how soil development influences contaminant reactivity. To achieve this goal, soils from two depths (30 and 100 cm) across a chronosequence (ages 3.5, 20, 69, 140, 200, and 908 ky) in the Oregon Coast Range were subjected to arsenic (As) adsorption isotherms, with As removal from solution serving as a proxy for soil-contaminant reactivity. Langmuir models were applied to isotherm data to quantify relationships between contaminant retention capacity, soil age and soil physicochemical properties, and data revealed that 20 ky soils from a 30-cm-depth had the greatest affinity for As sorption (8,474.5 mg kg). Chemical extractions revealed that amorphous (oxy)hydroxides were the dominant mineral phases governing As sorption, even in the presence of abundant crystalline oxides. Micro-X-ray fluorescence spectroscopy revealed a strong spatial correlation between As and Fe in reacted soils. The abundance of amorphous minerals within soils is controlled by the balance between their production from weathering of primary minerals and their loss from ripening to crystalline minerals, and because the mode, extent and minerals governing contaminant sorption determine solid-aqueous phase partitioning, this knowledge will assist in improving models for predicting Critical Zone processes that govern the sustainability of soil and water quality.

7. Estimating lime requirements for tropical soils: Model comparison and development.
PMID:日期:2023-04Acid tropical soils may become more productive when treated with agricultural lime, but optimal lime rates have yet to be determined in many tropical regions. In these regions, lime rates can be estimated with lime requirement models based on widely available soil data. We reviewed seven of these models and introduced a new model (LiTAS). We evaluated the models' ability to predict the amount of lime needed to reach a target change in soil chemical properties with data from four soil incubation studies covering 31 soil types. Two foundational models, one targeting acidity saturation and the other targeting base saturation, were more accurate than the five models that were derived from them, while the LiTAS model was the most accurate. The models were used to estimate lime requirements for 303 African soil samples. We found large differences in the estimated lime rates depending on the target soil chemical property of the model. Therefore, an important first step in formulating liming recommendations is to clearly identify the soil property of interest and the target value that needs to be reached. While the LiTAS model can be useful for strategic research, more information on acidity-related problems other than aluminum toxicity is needed to comprehensively assess the benefits of liming.

8. Modelling methane emissions and grain yields for a double-rice system in Southern China with DAYCENT and DNDC models.
PMID:日期:2023-03Methane (CH) is an important greenhouse gas that contributes to climate change and one of its major sources is rice cultivation. The main aim of this paper was to compare two well-established biogeochemical models, namely Daily Century (DAYCENT) and DeNitrification-DeComposition (DNDC) for estimating CH emissions and grain yields for a double-rice cropping system with tillage practice and/or stubble incorporation in the winter fallow season in Southern China. Both models were calibrated and validated using field measured data from November 2008 to November 2014. The calibrated models performed effectively in estimating the daily CH emission pattern (correlation coefficient, r = 0.58-0.63, p < 0.001), but model efficiency (EF) values were higher in stubble incorporation treatments, with and without winter tillage (treatments S and WS) (EF = 0.22-0.28) than that in winter tillage without stubble incorporation treatment (W) (EF = -0.06-0.08). We recommend that algorithms for the impacts of tillage practice on CH emission should be improved for both models. DAYCENT and DNDC also estimated rice yields for all treatments without a significant bias. Our results showed that tillage practice in the winter fallow season (treatments WS and W) significantly decreased annual CH emissions, by 13-37 % (p < 0.05) for measured values, 15-20 % (p < 0.05) for DAYCENT-simulated values, and 12-32 % (p < 0.05) for DNDC-simulated values, respectively, compared to no-till practice (treatments S), but had no significant impact on grain yields.

9. {"_":"Mechanisms and health implications of toxicity increment from arsenate-containing iron minerals through gastrointestinal digestion.","i":["in vitro"]}
PMID:日期:2023-02-17Inadvertent oral ingestion is an important exposure pathway of arsenic (As) containing soil and dust. Previous researches evidenced health risk of bioaccessible As from soil and dust, but it is unclear about As mobilization mechanisms in health implications from As exposure. In this study, we investigated As release behaviors and the solid-liquid interface reactions toward As(V)-containing iron minerals in simulated gastrointestinal bio-fluids. The maximum As release amount was 0.57 mg/L from As-containing goethite and 0.82 mg/L from As-containing hematite at 9 h, and the As bioaccessibility was 10.8% and 21.6%, respectively. The higher exposure risk from hematite-sorbed As in gastrointestinal fluid was found even though goethite initially contained more arsenate than hematite. Mechanism analysis revealed that As release was mainly coupled with acid dissolution and reductive dissolution of iron minerals. Proteases enhanced As mobilization and thus increased As bioaccessibility. The As(V) released and simultaneously transformed to high toxic As(III) by gastric pepsin, while As(V) reduction in intestine was triggered by pancreatin and freshly formed Fe(II) in gastric digests. CaCl reduced As bioaccessibility, indicating that calcium-rich food or drugs may be effective dietary strategies to reduce As toxicity. The results deepened our understanding of the As release mechanisms associated with iron minerals in the simulated gastrointestinal tract and supplied a dietary strategy to alleviate the health risk of incidental As intake.

10. {"_":" invasion of temperate deciduous forest stands alters the structure and functions of the soil microbiome.","i":["Quercus rubra"]}
10. {"_":"温带落叶林林分的入侵改变了土壤微生物组的结构与功能。","i":["红栎"]}PMID:日期:2023-01-11Invasive plants can modify the diversity and taxonomical structure of soil microbiomes. However, it is difficult to generalize the underlying factors as their influence often seems to depend on the complex plant-soil-microbial interactions. In this paper, we investigated how impacts on the soil microbiome across two soil horizons in relation to native woodland. Five paired adjacent invaded vs native vegetation plots in a managed forest in southern Poland were investigated. Soil microbial communities were assessed along with soil enzyme activities and soil physicochemical parameters, separately for both organic and mineral horizons, as well as forest stand characteristics to explore plant-soil-microbe interactions. Although did not significantly affect pH, organic C, total N, available nutrients nor enzymatic activity, differences in soil abiotic properties (except C to N ratio) were primarily driven by soil depth for both vegetation types. Further, we found significant differences in soil microbiome under invasion in relation to native vegetation. Microbial richness and diversity were lower in both horizons of vs control plots. Moreover, increased relative abundance of unique amplicon sequence variants in both horizons and thereby significantly changed the structure of the core soil microbial communities, in comparison to the control plots. In addition, predicted microbial functional groups indicated a predominant soil depth effect in both vegetation plots with higher abundance of aerobic chemoheterotrophic bacteria and endophytic fungi in the organic horizon and greater abundance of methanotrophic and methylotrophic bacteria, and ectomycorrhizal fungi in the mineral horizon. Overall, our results indicate strong associations between invasion and changes in soil microbiome and associated functions, a finding that needs to be further investigated to predict modifications in ecosystem functioning caused by this invasive species.
