Summary: Despite the negative effects of green tides, it is believed that they have a positive impact on carbon sequestration. This study examined the increase in dissolved organic carbon (DOC) and the molecular composition of DOC during a green tide caused by Ulva prolifera in the Yellow Sea. The findings show that green tides significantly shape coastal DOC, with macroalgae being an important source of recalcitrant DOC (RDOC) that has the potential for long-term carbon sequestration.

Summary: Colloids play an important role in the geochemical cycle of antimony (Sb) and have a significant impact on Sb mobility in contaminated groundwater. Organic colloids were found to closely associate with Sb, and the behavior of Sb was controlled by proteinlike substances and humus-like substances. Competitive adsorption of arsenic (As) and Sb suppressed the complexation of colloids with Sb, and the redox of the groundwater system also influenced Sb mobility. These findings provide new insights into the mechanisms involved in Sb fate affected by colloids and offer a theoretical basis for developing effective Sb and metalloid pollution remediation strategies.

Summary: This study investigates the lateral hydrological carbon flux for an estuarine marsh over the course of a year. The results show a significant correlation between imported and exported dissolved organic carbon and dissolved inorganic carbon, but not for particulate organic carbon. The marsh appears to be a net exporter of dissolved organic carbon and dissolved inorganic carbon, but a net sink of particulate organic carbon. The findings highlight the importance of lateral hydrological inflows/outflows in wetland carbon budgets, especially in the meta-ecosystem framework.

Summary: We investigated the changes in dissolved organic matter (DOM) from rain to stream water in a forested watershed. DOM supply from tree tissue and O layer caused an increase in dissolved organic carbon (DOC) concentration and specific UV absorbance at 254 nm (SUVA(254)) in rainwater. The decrease in DOC concentration and SUVA(254) with soil depth was not observed in the soil-percolating water. DOC concentration was low in both seepage and stream waters, with a seasonal variation observed in the stream water. The correlation between DOC concentration and absorbance at 254 nm (UV254) was significant, with different ratios observed among different sample types.

Summary: The priming effect (PE) has been extensively studied in soils but has contradictory results in aquatic ecosystems. Our experiments showed that the presence of easily degradable labile dissolved organic matter (LDOM) can significantly increase the biodegradation rate of nonlabile DOM (NLDOM), but this effect is only observed with specific types of LDOM. Microbial use of LDOM produces new microbial NLDOM that should be considered for accurate PE measurements. This temporary PE can have significant impacts on CO2 production in areas with frequent additions of LDOM. The addition of a new microbial inoculum had a stronger effect than adding LDOM or the PE.

Summary: Changes in precipitation and snowmelt timing in Arctic landscapes have led to warming and increased moisture, resulting in altered runoff and river discharge patterns. This study focuses on the mobilization and transport of dissolved organic matter (DOM) to Arctic coastal seas, and presents measurements of dissolved organic carbon (DOC) and chromophoric DOM (CDOM) in several river systems. The results show consistent seasonal and spatial variations in DOC and CDOM concentrations in the Arctic coastal systems. The study also provides insights into the transformations of DOM in river plumes and the effects of various processes during low river discharge periods.

Summary: Rainfed rice in sub-Saharan Africa faces the challenges of drought and phosphorus deficiency. This study examined the response of different rice genotypes to variable water stress under conditions of phosphorus deficiency. The results showed that the effects of phosphorus supply on shoot weight were greater than the effects of water supply. Reduced water supply did not enhance phosphorus stress, and the stress response varied among genotypes. Root biomass production and root efficiency were found to be important factors in combating the combined stresses of water and phosphorus. The study confirmed the superior performance of the genotypes Chhomrong Dhan and FOFIFA 172 found in the field.

Summary: Nitrogen is crucial for the production of nutritious feeds and foods, but the production and use of fertilizer nitrogen pose a major threat to environmental health and sustainability. It is important to promote consumer acceptance and awareness of proteins produced by highly effective microorganisms as an alternative to proteins obtained from plants and animals with low nitrogen efficiencies. Additionally, recovering and upgrading used nitrogen from secondary resources and integrating biological nitrogen fixation into feed and food supply chains are promising solutions for a more sustainable agriculture.

Summary: Layered transition metal molybdates (LTMs) are proposed as slow-release fertilizer compounds for micronutrients molybdenum (Mo), zinc (Zn), and copper (Cu). LTMs were successfully prepared and characterized, and their solubility in water was tested. The LTMs showed limited stability in acidic conditions, so co-compaction with pH neutral or alkaline macronutrient carriers was explored. A Zn-based LTM co-compacted in a muriate of potash (MOP) carrier showed a slow and constant release rate of both Mo and Zn, making it a potential slow-release fertilizer or raw material for non-acidic fertilizers.

Summary: Globally, fertilizer caking during transport and storage causes various issues, including breakdown, dust, blockages, and inconsistent application. Coatings, especially those with hydrophobic properties, can reduce moisture uptake and caking while maintaining nutrient release. In this study, wax coatings, both natural and synthetic, were applied onto fertilizer granules with powders to create surface roughness, which effectively reduced contact between condensed water droplets and the surface, leading to lower moisture ingress. The adhesive strength and nutrient release rate were evaluated using laser surface microscopy. The results showed that wax-only coatings reduced moisture uptake by up to 30%, while coatings with wax and rougheners achieved reductions between 56% and 80%. Beeswax coatings with micronutrient rougheners reduced moisture uptake by over 65% while ensuring uninterrupted nutrient supply. Therefore, these hydrophobic coatings can enhance the physical characteristics of fertilizer without compromising nutrient release kinetics.

Summary: Current radiocesium (137Cs) models for predicting 137Cs transfer from soil to plants are inadequate and do not consider the mineralogy of the clay fraction. This study conducted a pot cultivation experiment to test the hypothesis that information on mineralogy can improve predictions. The results showed that the transfer factor (TF) of 137Cs varied significantly across different clay groups and doses, and was best predicted by the soil solution 137Cs and K concentrations. X-ray diffraction (XRD) analysis of phyllosilicate groups provided the strongest predictive power for 137Cs bioavailability in plant substrates.

Summary: The pathways of cadmium (Cd) loading into cacao beans (nibs) have been investigated using a stable isotope (108Cd) pulse-chase experiment. The results suggest that Cd is likely transported from the stem, branches, or mature leaves to the nibs through phloem-mediated redistribution, rather than directly through the xylem.

Summary: Current P fertilizer recommendations must be revised to balance crop yield, water quality, and finite P resources. Current soil P tests do not provide the necessary insights. The oxalate extraction method shows promise as an agri-environmental soil test as it measures the total pool of P and the maximum P sorption capacity. These insights are crucial for assessing crop response, P loss risk, and the judicious use of finite P reserves.

Summary: This article investigates the effects of metal mixtures and species interactions on biological communities and finds that the sensitivity of communities depends on the correlation of sensitivities among single species to single metals. The results suggest that functional endpoints are less sensitive than structural endpoints under metal mixture stress, indicating functional redundancy. Antagonistic metal mixture interactions found in single species can also exhibit antagonistic and synergistic effects in communities. Additionally, the interactions of metal mixtures in communities gradually shift from antagonism to non-interactions with increasing correlation of single-species sensitivities among the single metals. Overall, functional redundancy can lead to reduced biodiversity, and synergisms can emerge at the community level without any synergisms on the single-species level.

Summary: This study investigates the feasibility and mechanisms of a chemical-free nanobubble-based AOP for treating organic micropollutants in water. The results show that the oxygen nanobubble AOP has a significantly higher removal efficiency compared to air and nitrogen nanobubbles. The treatment performance is not affected by pH and the presence of ions. Higher initial concentrations of the micropollutant lead to slower treatment processes, but similar removal performance is achieved in the end. The presence of organic matter reduces the removal rate of the micropollutant. The results have practical feasibility for water and wastewater treatment.
