This study proposes an innovative geophysical monitoring framework for detecting field soil cracking by combining the actively heated fiber-optic (AHFO) method and distributed fibre optical sensing (DFOS) based on optical frequency domain reflectometry (OFDR) technique, referred to as AH-OFDR framework. Laboratory calibration tests, field monitoring tests, numerical simulations, and sensitivity analyses were employed to comprehensively evaluate the feasibility, effectiveness, and limitations of the AH-OFDR framework for soil crack monitoring. Laboratory calibration confirmed that the DFOS-OFDR technique achieves a minimum spatial resolution and readout accuracy of 1 mm, along with a temperature measurement accuracy of ±0.1 °C. Field monitoring verified that the AH-OFDR framework can accurately detect soil cracks ranging in width from 0.01 m to 0.12 m. Additionally, numerical simulations not only validated the effectiveness of the AH-OFDR framework across a broader range of crack widths, from 0.01 m to 0.50 m, but also established a quantitative relationship between temperature changes and the spatial distribution of crack positions and widths. Notably, a critical crack width threshold of 0.30 m was identified within the AH-OFDR framework, significantly impacting the prediction of soil crack widths. Sensitivity analysis demonstrated the remarkable crack detection capabilities of the AH-OFDR framework, irrespective of the soil crack width and spacing. The AH-OFDR framework holds substantial potential as an innovative and high-resolution observational method for advancing our understanding of diverse geological and hydrogeological processes.</div></div>","PeriodicalId":12511,"journal":{"name":"Geoderma","volume":null,"pages":null},"PeriodicalIF":5.6,"publicationDate":"2024-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142585975","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

If so, it would make sense to reflect this in the models used, by incorporating an inert carbon (C) pool. We hypothesized that such inert pool models would fit better to incubation data than existing models and give more reliable long-term predictions. We evaluated this by fitting the models to data from a recently compiled extensive dataset of biochar incubations. The inclusion of an inert pool enhanced the model fits over first-order models in most cases. However, inert pool models overestimated biochar persistence compared to the measured outcomes. By contrast, the double first-order model, which has been the most widely used to date, underestimated biochar persistence even in the short term.

Efforts to increase root production and depth distribution through planting deep rooted crops and selective crop breeding have been identified as a promising strategy to achieve these goals. However, we lack a complete understanding of how the decomposition of roots in the deep soil (e.g., below 30 cm), contributes to SOM formation and stabilization. Here using unique soil-biomass microcosms in the field to trace ¹³C enriched root litter to a depth of 90 cm, we show that as decomposition dynamics change with depth, so do the SOM formation pathways. At our study site, root residues decomposed faster in the top 0–30 cm, achieving 97 % mass loss by 13 months of incubation compared to 77 % and 81 % in the 30–60 and 60–90 cm depths, respectively. Litter derived carbon (LDC) was preferentially recovered as stable mineral associated organic matter (MAOM), primarily within aggregates, with 67 % more in the 0–30 cm than in the 60–90 cm depth. At depth, root residues decomposed slower and accumulated as the less stable particulate organic matter (POM) within macroaggregates with 145 % more LDC recovered in light POM in the 60–90 cm depth than the 0–30 cm depth. We found that bulk SOM measurements were too coarse to elucidate the likely fate of newly incorporated litter in the soil, but our detailed fractionation demonstrated the relative contribution of new root inputs to functionally different SOM pools, MAOM and POM, and allowed us to interpret the role of microaggregates in these dynamics in new detail, particularly microaggregates within macroaggregates (i.e., occluded microaggregates). Our results highlight the importance of balancing the trade-off between MAOM and POM formation when considering strategies to enhance both carbon sequestration and soil health in agroecosystems. If POM is critical for aggregate formation and microaggregates play an important role in MAOM formation, efforts to increase soil carbon sequestration need to focus on both fractions and on supporting overall soil structure.</div></div>","PeriodicalId":12511,"journal":{"name":"Geoderma","volume":null,"pages":null},"PeriodicalIF":5.6,"publicationDate":"2024-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142586566","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The increased abundance of soil nematodes in forest gaps was also associated with increased soil pH presumably related to reduced input of pine needles. Furthermore, the abundance (−5.3 %) and diversity (−25.1 %) of soil nematodes decreased with gap age, presumably because of increased soil temperature and decreased soil moisture in the four- compared to the two-year-old gaps.

It’s demonstrated that amendments facilitate the metal immobilization via adjusting soil pH and metal availability, while the underlying mechanism on amendments improving phytoremediation efficiency remains unclear. In our previous studies, the phytoremediation efficiency of <em>Quercus</em> spp. for Cd and Zn was improved by application of soil amendments in a three-year field trial located in Hangzhou, China. Here, we collected the soil samples from the above mentioned experiment and further compared the characteristics of the rhizosphere bacterial community of <em>Quercus texana</em> and <em>Quercus fabri</em> amended with rice straw biochar, palygorskite, and a combination of rice straw biochar and palygorskite in Cd- and Zn-contaminated soils. There were no significant differences in bacterial diversity between the <em>Q. texana</em> and <em>Q. fabri</em>, which were characterized by a high and low accumulation of heavy metals. However, rhizosphere bacterial network of both species exhibited significant responses to the different soil amendments. Combined biochar increased the complexity and stability of bacterial networks, which was manifested mainly as an increase in network cohesion, negative:positive cohesion, and robustness. Partial least squares path modeling demonstrated that network stability was directly influenced by complexity (path coefficient = 0.551, <em>p</em> &lt; 0.05) and keystone taxa (path coefficient = -0.29, <em>p</em> &lt; 0.05), where keystone taxa can serve as a significant predictor variable for network stability. Furthermore, network complexity and stability were significantly correlated with heavy metal accumulation in <em>Quercus</em> spp., suggesting potential linkages between microbial network properties and phytoremediation efficiency. Together, the results emphasize that combined biochar enhances the complexity and stability of rhizosphere bacterial network, ultimately improving phytoremediation efficiency and biomass. Lower network stability in the rice straw biochar and palygorskite treatments may pose ecological risks.

Zeolites possess intricate internal frameworks that allow them to modify soil structure and texture, thereby impacting soil hydrological properties. This potential offers opportunities to control soil and groundwater pollution as well as optimize irrigation management practices. In this study, three sandy-loam soils and a silty-loam soil were collected and mixed with different amounts of synthetic zeolite derived from coal fly ash. Repacked soil samples were combined with four levels of zeolite ranging from 1% to 10% by weight and were then hydraulically characterized. This included measuring soil water retention curves (SWRCs) of soil-zeolite mixtures. The data revealed, in accordance with recent research findings, that zeolite influences the hydraulic behavior of soils. In general, we observed that, as the percentage of zeolite increases in the soil, the SWRCs are shifted upwards. This effect is fundamental for explaining the observed changes in the whole set of investigated soil hydraulic properties. The observed changes are also fundamental to evaluate selected soil physical quality (SPQ) indices of agronomic interest, which are investigated in depth in the present research. A specific focus was on the impact of zeolite on modifying the soil’s capacity to retain water, hence on the energy required by plants to acquire a unit mass of soil water (referred to as integral energy, E_I). Finally, the ANOVA test, linear regression, and multivariate analysis were performed on the entire dataset to support, from a statistical standpoint, the observed correlations between SPQ indices and zeolite amounts.

This study selected soils from three sites in Shouguang (a typical representative intensive planting area), i.e., greenhouse monoculturing for 20 years (G20), greenhouse monoculturing for 10 years (G10), and an adjacent rotation field (F) for physicochemical property determination and high-throughput pyrosequencing. The results showed that, contrary to the vertical characterization of soil bacterial community composition, the 2-m soil was dominated by Methylomirabilota, a nitrate/nitrite-dependent anaerobic methane oxidizer, uncovered for the first time in the soil habitat. This was attributed to the high levels of dissolved organic carbon (DOC, 201.2–255.7 mg kg⁻¹), proving that applying C-rich organic fertilizers, e.g. plant residues, is effective in preventing accumulated nitrate from moving downward and threatening groundwater in greenhouse soils. Besides, greenhouse cultivation increased the inter-layer composition differences of the bacterial community, and compared with the abundant, the rare subcommunity showed higher sensitivity to environmental changes. The total nitrogen most significantly affected the bacterial community composition and assemblage. Therefore, 20 years of consecutive monocropping significantly decreased the microbial co-occurrence network complexity and species dispersal rate, yielding a low-fitted neutral community model (NCM) and more specialized ecological niches, especially for the rare subcommunity. As far as is known, this is the first study that explores the likely changes in the bacterial community composition and quantifies the responses of the rare subcommunity to long-term greenhouse cultivation at this soil depth.

Although other indicators such as CO₂ mineralization, N and C cycling enzymes, PLFA and ARR showed fewer differences among crop production practices, all were greater under prairie grassland than cropland.
