Summary: Developing commercial-level high active mass-loading electrodes is crucial for the practical application of supercapacitors. This study presents a self-standing biochar electrode with high active mass-loading, which exhibits excellent capacitive performance due to its conductive carbon skeleton, abundant N/O dopant, and 3D porous structure. The electrode shows promising potential for practical application, as demonstrated by its ability to power various electronic devices.

Summary: This study investigated the effects of root exudates on microbial-mediated nitrogen transformations in low fertility soils through laboratory incubation. The results showed that different root exudates influenced soil respiration, dissolved organic carbon, and dissolved organic nitrogen concentrations. Analysis of measured pools revealed that the recovery of root exudate carbon was lower in sandy loam soil. Additionally, organic acids had a greater impact on nitrogen mineralization and fixation rates. Root exudate addition also altered soil pH and organic nitrogen concentrations.

Summary: Groundwater nitrate contamination is a global issue that threatens water supply, especially in arid and semiarid piedmonts. An extensive hydrogeochemical investigation was conducted in a heavily human-impacted semiarid piedmont in North China. The study found that the groundwater in this area is alkaline and has high variations of salinity. The concentration of nitrate in the groundwater exceeds the permissible limit recommended by the World Health Organization. Anthropogenic inputs from residential land usage are responsible for the nitrate enrichment and salinity increase. The study also assessed the non-carcinogenic risks posed by nitrate, nitrite, and ammonia through dermal and oral pathways for different population groups. The findings indicate that all population groups are at risk, with minors being more susceptible. Measures such as improving awareness, environmental protection, and targeted water treatment are recommended for sustainable groundwater resource development in arid and semiarid piedmonts.

Summary: The micro-structural evolution of loess and its impact on macro-mechanical properties when exposed to chemicals were studied. The corrosion of cement between particles under acetic acid environments and salt-induced swelling under saline conditions played crucial roles in the micro-structural deterioration.

Summary: Nitrogen addition has different effects on soil respiration and its temperature sensitivity. It increases autotrophic respiration but decreases heterotrophic respiration. Overall, nitrogen addition decreases both soil respiration and its temperature sensitivity. The optimal nitrogen addition rate to maintain soil as a carbon sink is around 100-150 kg N ha(-1) yr(-1), and soil respiration is influenced by soil pH, C:N ratio, and respiratory quotient.

Summary: This study showed that inoculation with Funneliformis mosseae can improve plant growth and root exudate compositions, increase soil glomalin concentrations, and enhance soil aggregate stability. The mycorrhizal fungi can mitigate drought damage by altering root exudate components and soil protein levels in the rhizosphere.

Summary: The study evaluated the accuracy of using microbiome data to predict soil health metrics, with biological health ratings better predicted than chemical or physical ratings. Models trained at the highest taxonomic resolution were the most accurate, with losses in accuracy resulting from rarefying, sparsity filtering, and aggregating at higher taxonomic ranks.

Summary: The study evaluated the effectiveness of 28 commercial AMF inoculants in promoting plant growth, with most of them failing to significantly enhance mycorrhizal colonization under greenhouse conditions. Effects on plant growth under field conditions were found to be dependent on changes within the mycorrhizal community.

Summary: This review focuses on the contribution of cover crops to soil properties. It discusses the advantages and uses of different types of cover crops, such as grass species for soil cover and decomposition, broadleaf species for quick decomposition and residue release, and leguminous species for nitrogen fixation. It also highlights the benefits of cover crops in improving soil health, including reducing soil density, improving soil structure and hydraulic properties, and increasing organic carbon and nutrient content. Additionally, cover crops promote microbial activity and diversity. Proper management of cover crops can enhance soil health as an essential practice in soil conservation.

Summary: Soil organisms play important roles as ecosystem engineers in promoting soil aggregation, enhancing soil quality, and nutrient cycling. The complex composition of biogenically excreted organic matter can either promote or inhibit aggregation, affecting aggregate formation, stability, and transport through various functional roles.

Summary: Soil salinization is a major cause of global soil degradation, and accurate information is often unavailable in data-poor regions. This study developed a hybrid machine learning method to create a high-resolution soil salinity map, which showed high accuracy. The proposed method can aid precise management and contribute to biodiversity restoration, land degradation reduction, and avoidance of future food output reductions.

Summary: The ability of global agricultural soils to store carbon to mitigate rising CO2 concentrations and the associated costs have been a focus of soil science for decades. Various methods have been used to estimate additional soil organic carbon storage, with this study taking a unique approach focusing on photosynthesis. Using a Fermi approach parameterized by literature data, the study estimated global net C inputs and additional C storage in cropland soils, advocating for a shift towards a wider ecosystem perspective starting with photosynthesis.

Summary: This study investigated the properties of phosphoric acid-modified biochars (PABCs) prepared at different pyrolysis temperatures. PABCs prepared at higher temperatures had a higher proportion of micropores and showed improved adsorption capacity and rate for sulfadiazine (SDZ). The enhancement in adsorption was attributed to the confinement effect of hydrophobic cavities from the microporous structure and the pi-pi electron-donor-acceptor interaction. PABCs exhibited stable adsorption capacities at a wide pH range or high concentrations of coexisting ions.
