However, amidst climate change and human activities, biocrust coverage is encountering the risk of degradation. The restoration of degraded biocrusts and the construction of artificial ones are regarded as promising technologies for combating soil degradation. Although clay minerals are a crucial abiotic factor in biocrust formation and are directly influence their development and succession, they have not gained widespread attention. The aim of this study was to investigate the mechanism of action of clay minerals in biocrusts. Various quantities of sepiolite were amalgamated with cyanobacteria—<em>Microcoleus vaginatus</em> (ratios of 1:0, 1:10, 1:20, 1:50, 1:100; cyanobacteria dry weight to sepiolite weight), to construct artificial biocrusts and observe the formation and development of them. The results showed that the addition of small quantities of sepiolite (ratios of 1:10 and 1:20) not only facilitated the accumulation of cyanobacterial biomass (1.47–1.86 times) and exopolysacchrides (EPS) (1.73–2.58 times) compared to the control (ratio of 1:0), but also notably enhanced the accumulation of total carbon, total organic carbon, and microbial biomass carbon, highlighting its potential in enhancing the carbon sequestration capabilities of biocrusts. Scanning electron microscope (SEM) analysis revealed that sepiolite serves as a “receiver and bridge” within the biocrust structure, enhancing its compactness and stability, thereby fostering the growth of cyanobacteria and facilitating nutrient transport. Further, Fourier Transform Infrared (FTIR) and X-Ray Photoelectron Spectroscopy (XPS) analysis reviewed changes in some functional groups of EPS and sepiolite after mixing, validating that EPS can function as a “binder” to unify particles. Our findings demonstrate that the incorporation of clay minerals can facilitate biocrust formation, presenting a practical and economical approach, and providing a novel perspective for constructing artificial biocrusts and rehabilitating degraded desert soils.</div></div>","PeriodicalId":49503,"journal":{"name":"Soil & Tillage Research","volume":null,"pages":null},"PeriodicalIF":6.1,"publicationDate":"2024-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142416409","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The decomposition of the carbon present in crop residues was critical for N₂O emissions. Lower EF_N2O of BGR relative to AGR were related to slower C decomposition, which was not predicted by the biochemical characteristics. It is also likely that BGR were less conducive than AGR to develop into hotspots for N₂O emission because of the roots’ finer distribution and closer contact with soil particles.

This modification aimed to quantify the impact of pore water salinity on soil compression. To validate the constitutive model, a numerical analysis of an isotropic compression test was carried out.

The unprecedented availability of Sentinel optical and radar data on cloud computing platforms, such as the Google Earth Engine (GEE), has created new possibilities for developing soil prediction models from the local scale to the planetary scale. However, there is a paucity of literature on the effects of Sentinel sensor selection and integration and radar data utilization strategies on mapping the C:N ratio. In this study, we explored the use of multiyear Sentinel-1 radar and Sentinel-2 optical data obtained from the GEE platform combined with the digital soil mapping (DSM) technique to map the soil C:N ratio at the European scale. The performance of soil prediction models, which were constructed using two modeling techniques (random forest and support vector machine), derived under multiple scenarios based on optical, radar and commonly used auxiliary data (climatic and topographic variables) combined with the LUCAS 2018 soil dataset, was evaluated by a cross-validation technique. The results showed that the modeling performance varied with the selection and integration of Sentinel observations, as well as the configuration of the radar data. Models based on single polarization performed the worst across all scenarios related to Sentinel-1, with cross-polarization performing better than copolarization. Models that utilized Sentinel-1 data from ascending orbits outperformed those that utilized data from descending orbits. The application of Sentinel-1 backscatter information derived from different orbits and polarization modes resulted in improved prediction accuracy. Our study also demonstrated the potential of integrating multiyear Sentinel satellite data via the GEE to map the continental-scale C:N ratio. The model based on Sentinel-1 data outperformed the one built on Sentinel-2 data, whereas combining Sentinel-2 optical data with Sentinel-1 radar data led to more accurate predictions. The variable importance results indicated that optical data and backscattering information from Sentinel observations are the most important groups of variables for soil C:N ratio mapping compared to the other variable groups (terrain and climate data). The digital soil maps generated under the different scenarios exhibited detailed patterns with significant spatial variation, with similar overall trends but slightly different details.</div></div>","PeriodicalId":49503,"journal":{"name":"Soil & Tillage Research","volume":null,"pages":null},"PeriodicalIF":6.1,"publicationDate":"2024-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S016719872400312X/pdfft?md5=7b4612ad26bc902ced72e0b24708d876&pid=1-s2.0-S016719872400312X-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142314187","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}

High levels of SOC in sandy soils are difficult to attain especially when precipitation levels are very low, contributing to low biomass production, and increased decomposition of organic matter. While CT practices are known to reduce SOC through the breakdown of soil aggregates, accelerated decomposition of soil organic matter, and promote erosion, CST methods (i.e., mulch tillage, no tillage, reduced tillage, ridge tillage, etc.) offer the potential to preserve soil aggregates and increase SOC concentration. Analyzing 55 peer-reviewed publications in arid and semi-arid climates with ≥ 45 % sand content, this study compared SOC content between CST and CT over short- and long-term periods (349 paired observations). Results showed that CST increased SOC in sandy soils, with an estimated 12.74 ± 1.46 % increase. Specifically, reduced tillage (RdT), mulch tillage (MchT), and no tillage (NT) exhibited the highest increases of SOC by 18.94 ± 2.48 %, 11.45 ± 2.46 %, and 10.06 ± 2.46 %, respectively, compared to CT. Studies with durations of up to 15 years (n = 297) showed a progressive increase in SOC concentrations under CST; however, the long-term stability of the accrued carbon content in sandy soils of arid and semi-arid climates is still uncertain, as studies extending beyond 15 years (n = 52) did not demonstrate significant changes in SOC levels. CST significantly raised SOC concentrations in precipitation up to 600 mm, though no significant changes were observed for precipitation over 600 mm. In soils with over 56 % sand content, CST increased SOC by approximately 13 %.

To evaluate the C sequestration potential in hilly terrain it is essential that not only changes in vertical C fluxes (more C input and/or reduced mineralisation), but also lateral soil organic carbon (SOC) redistribution due to erosion processes are considered. Tillage has been identified as an important contributor to soil translocation processes and a modulator of SOC dynamics. Nevertheless, the focus of most studies dealing with SOC redistribution still lies on water erosion. Therefore, the aim of this study is to assess the impact of tillage erosion on C fluxes in the intensively cultivated loess region (200 ha) in the Czech Republic. The coupled water and tillage erosion and C turnover model SPEROS-C was used to analyse the effect of six decades of erosion/deposition upon C fluxes, whereas a specific focus was set on the importance of tillage erosion processes. The results indicate that tillage erosion (TIL) is an important driver of C dynamics in the study area, especially at slope shoulders where a substantial decline in SOC was modelled. Water erosion (WAT) is the most dominant process in the region. However, the model results reveal an increase in erosion-induced C sequestration potential by 37 % after 60 years of simulation when effect of TIL is considered. Moreover, it is interesting that TIL reduced the total sediment delivery from the monitoring site via a change in topsoil SOC patterns. In other words, tillage lowered water erosion-induced sediment transport. Overall, considering the overlooked impact of tillage erosion led to a substantial shift in the role of soil erosion on SOC dynamics. The climate mitigation measures based on adapted agricultural management to increase SOC sequestration are often in-line with soil conservation measures. Our results indicate that such an adaptation might be less effective as the erosion-induced C sink effect declines.</p></div>","PeriodicalId":49503,"journal":{"name":"Soil & Tillage Research","volume":null,"pages":null},"PeriodicalIF":6.1,"publicationDate":"2024-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0167198724002885/pdfft?md5=d5281a7027dcba1de1c652c5f42a233a&pid=1-s2.0-S0167198724002885-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142242359","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}
