Fe (hydr)oxides have a substantial impact on the structure and stability of soil organic carbon (SOC) pools also drive turnover processes via reduction–oxidation reactions. Currently, many studies paid much attention to matter–Fe mineral–microbial interactions SOC turnover, while there is few research how exogenous addition abiotically regulates intrinsic mechanisms Fe-mediated conversion. The study investigated coupling process artificial humic acid (A-HA) Fe(hydr)oxide, mechanism inner-sphere ligands, capacity for sequestration using transmission electron microscopy, thermogravimetric, x-ray photoelectron spectroscopy, wet-chemical disposal. Furthermore, spherical aberration-corrected scanning microscopy–electron energy loss spectroscopy Mössbauer spectra been carried out demonstrate spatial heterogeneity A-HA/Fe reveal relationship between increase in Fe-phase crystallinity redox sensitivity accumulation carbon. Additionally, dynamics structures microscale, distribution carbon–iron microdomains, cementing-gluing effect can be observed constructing nonliving anthropogenic soils, confirming that formation stable aggregates an effective approach achieving indirect protection. We propose inputs, specifically A-HA, could exert but hitherto unexplored geochemistry iron–carbon anoxic water/solid soils sediments.

Abstract Herein, the feasibility of artificial black soil (ABS) derived from hydrothermal humification-hydrothermal carbonization (HTH-HTC) for restructuration weak was verified. This study breaks through long history formation and evolution, obtains reconstructed anthropogenic (AS) system which only takes one month, further application rice seedlings. HTH-HTC by-products are slightly acidic, facilitates effective nutrient uptake prevention wilt diseases acid-loving AS mainly consists inherent components retained such as SiO 2 minerals, exogenous humic substances hydrochar, introduced by humification processes. Results exhibit that has high contents ammonium nitrogen, organic matter, carbon, abundant porous structure transport water holding, especially, community diversity richness microbial gets expected recovery new beneficial bacteria (such Caballeronia calidae ) or fungi Humicola appear. Positive effects on agronomic traits in seedlings quantified. As a general result, this supports sustainable agriculture, provides novel strategy to tackle already-omnipresent land degradation misuse larger scale accidents.

Transparent soil (TS) presents immense potential for root phenotyping due to its ability facilitate high-resolution imaging. However, challenges related transparency, mechanical properties, and cost hinder development. Herein, we introduce super-transparent (s-TS) prepared via the droplet method using low acyl gellan gum hydroxyethyl cellulose crosslinked with magnesium ions. The refractive index of solution (1.345) closely aligns that water (1.333) (1.340), thereby significantly enhancing transmittance hydrogel-based transparent soil. Optimal (98.45%) is achieved polymer concentrations ranging from 0.8 1.6 wt.% ion between 0.01 0.09 mol·L−1. After 60 days plant cultivation, s-TS maintains a exceeding 89.5%, enabling detailed visualization growth dynamics. Furthermore, exhibits remarkable withstanding maximum compressive stress 477 kPa supporting load-bearing depth 186 cm. This innovative approach holds promising implications advanced studies, fostering investigation heterogeneity development selective expression under controlled conditions.

Soil organic matter (SOM) plays a pivotal role in enhancing physical and biological characteristics of soil. Humic substances constitute substantial proportion SOM their increase can improve crop yields promote agricultural sustainability. While previous research has primarily assessed the influence that humic acids (HAs) derived from natural water have on soil structure, our study focuses impact HAs aggregation under different fertilizer regimes. During summer cropping season, maize was cultivated synthetic treatments. The treatment utilized barley (Hordeum vulgare L.) hairy vetch (Vicia villosa R.) as an amendment five days prior to planting. included (NPK) applied at South Korea's recommended rates. resulted significant improvements aggregates stability (mean weight diameter, MWD; p < 0.05) compared application.

A search for novel sources of biologically active compounds is at the top agenda biomedical technologies. Natural humic substances (HSs) contain a large variety different chemotypes, such as condensed tannins, hydrolyzable terpenoids, lignins, etc. The goal this work was to develop an efficient separation technique based on solid-phase extraction (SPE) isolation narrow fractions HS with higher biological activity compared initial material. We used lignite acid parent material, which showed moderate inhibition toward beta-lactamase TEM 1 and antioxidant activity. applied two SPE techniques: first one gradient elution water/methanol mixtures material sorbed pH 2, second implied by difference in pKa value use sequential sorption from 8 3. cartridges Bond Elute PPL (Agilent) were fractionation experiments. techniques yielded 9 7 fractions, respectively. All characterized using high-resolution mass spectrometry assays, including determination (TEM 1) acidity-based demonstrated substantial advantages: it enabled components, outcompeting step (sorption 8). It orthogonality regard polarity-based technique. Good perspectives are shown developing 2D scheme combination polarity approaches reduce structural heterogeneity HS.
