Summary: This study investigated four deep, well-developed soils along a basalt-sandstone transition, revealing the influence of soil parent material on their genesis, chemical and mineralogical composition. Basalt soils were characterized by high clay contents and specific mineral components, while the sandstone soil had lower clay content and different mineral composition. The different soil types along the toposequence exhibited varying fertility levels and unique characteristics, likely influenced by the formation of an interstratified clay mineral complex.

Summary: This study demonstrates the impacts of rainfed agriculture on hydrology through remote sensing analysis, field studies, and simulation experiments. The findings reveal that the expansion of farming in the South American plains has led to increased flood coverage and shallower groundwater levels, which are attributed to the reduced rooting depths and evapotranspiration in croplands. These results highlight the escalating flood risks associated with rainfed agriculture expansion.

Summary: The article introduces the SMERGE root-zone soil moisture product that covers the continental United States from 1978 to 2019. Machine learning techniques were used to downscale SMERGE to field-scale resolutions. The downscaled results were validated using in situ data and comparisons with other retrieval data. The study found that RF outperformed XGBoost and GBoost in different periods and models. The downscaled results showed improved correlation and reduced RMSE, allowing for diverse hydrometeorological and agricultural applications.

Summary: Increasing soil organic content can enhance soil water retention and available water capacity, with different effects on different soil types. Fine sandy soil shows a more significant response to organic matter increase compared to clay loam. Conservation agriculture practices may partially offset the soil water retention effects, but different crop rotations could have varying impacts on yields.

Summary: Excessive salts in degraded sodic soils exacerbate soil properties, which need to be remediated and restored in a judicious way. This study aimed to mitigate the harmful effects of sodic soils and maintain soil fertility through need-based silvipastoral systems. The results demonstrated that different tree species and grasses significantly influenced soil properties and plant growth, with the A. nilotica + C. gayana silvipastoral system being the most effective for restoring degraded sodic soils.

Summary: Correlations between organic carbon (OC) and fine mineral particles play a significant role in binding and increasing the persistence of organic matter (OM). The study shows that finer mineral particles may influence the storage of OC in agricultural soils through a thicker accrual of OM at the same mineral surface area within fine fractions, regardless of clay content limitations.

Summary: The study focused on the spatiotemporal variation of soil and water salinity in an artificial salt marsh. A practical model for predicting soil salinity was developed and validated using numerical simulation and field measurements. The results indicate that stable brackish ecotones can be created in artificial salt marshes using the developed numerical model as a design tool.

Summary: Grain size in rice is determined by the GS3 and GW2 genes, with mutations in these genes playing a significant role. Mutant alleles of these genes are important for breeding programs, but solely incorporating favorable alleles is not enough to improve grain size. It is crucial to understand the regulatory networks, interactions, and pathways of GS3 and GW2 for marker-assisted selection in future breeding programs. Additionally, the selection of grain size is not dependent on 1000-grain weight in specific germplasm.

Summary: In this study, a novel genotype by yield*trait (GYT) biplot approach was used to select superior durum wheat advanced lines based on multiple traits. The GYT biplot explained a higher proportion of total variation compared to the genotype by trait (GT) biplot. By analyzing the biplot, it was found that certain genotypes exhibited desirable combinations of traits for higher yield, making them potential candidates for further testing in multi-location trials.

Summary: This study investigated how metal toxicity affects the oxygen-evolving complex in spinach, specifically the coordination structure of the Mn4CaO5 cluster in photosystem II. The presence of Cu2+ and Pb2+ disrupted the essential chloride ions, leading to impaired oxygen release. Additionally, the accumulation of these metals altered the leaf structure, reducing stomatal opening and pigment concentration, ultimately impacting photosynthesis and plant growth.

Summary: A study investigated the effect of ruminant intestinal waste on anaerobic digestion of cow manure, finding that a ratio of 9:1, 7:3, and 1:1 of cow manure to intestinal waste demonstrated a good synergistic effect, resulting in higher cumulative biogas yields. Furthermore, a 9:1 ratio of cow manure to intestinal waste showed the highest removal rates of chemical oxygen demand (COD), volatile solids (VS), and total solids (TS).

Summary: The current study aims to explore the free radical scavenging ability of Saussurea heteromalla extracts and evaluate its compound through bioassay-guided purification. The n-hexane extract of the whole plant is found to be most active, and the active fraction is purified using HPLC-DAD, leading to the isolation of octocrylene. This compound has good free radical scavenging activity and is widely used in the cosmetic industry as a sun protectant but is not commonly reported from botanical sources.

Summary: The conversion from conventional open-field cultivation system to plastic shed cultivation system has resulted in serious soil contamination by heavy metals, with the PSS system exhibiting more severe pollution than the OFS system. The heavy metal pollution level varied among different regions, with southern Shaanxi showing the highest contamination. Although the selected heavy metals were below the national limited standard on average, the accumulation of Cd and Pb in both cultivation systems was considerable, and the years of cultivation in PSS led to increased Cd, Hg, and Zn contents in the soil. Soil nutrients and heavy metals had different interactions depending on the crop management techniques used in each region.

Summary: Arsenic (As) contamination of water is a crucial issue that affects human health. Bentonite clays have been investigated as a potential candidate for treating As-contaminated water. In this study, bentonite deposits in Khyber Pakhtunkhwa, Pakistan, were evaluated for their As adsorption capacity and mechanism. The results showed that Nowshera bentonite had the highest adsorption capacity and affinity for As. The findings suggest that the clay quarry in Nowshera could be utilized for the effective purification of As-polluted drinking water.

Summary: This study investigated the health and environmental impacts of coal mining activities in the Makarwal coal mining area in Pakistan. Soil samples collected from the affected areas showed high concentrations of toxic metals such as Ni, Cd, Cr, Cu, Zn, and Pb. Factor analysis indicated that the contamination in the area is likely associated with the geological ore strata in the coalfield. Based on geoaccumulation and ecological risk indices, certain trace elements pose a high risk to humans and the ecosystem. The source of metal contamination is likely from exposed sedimentary rocks, including limestone, dolomite, sandstone, and coal.
