Summary: The use of poor-quality irrigation water in drylands leads to soil salinization and sodicity, which contribute to land degradation. This study investigates the effects of water quality and irrigation mode on solute transport conditions in terms of ion exchange. The results show that flow velocities do not significantly affect pH, EC, and ion concentrations, but decrease in the presence of sodic water, indicating the destructive effect of Na+ in the soil. Overall, sodicity causes significant changes in flow dynamics and ion concentrations, creating favorable conditions for secondary salinization in low permeable soil systems.

Summary: The study shows that microbes can adapt to a two-compartment life cycle by changing either replication rates or migration rates, depending on the initial values of traits, the initial distribution across the two compartments, the intensity of competition, and the time scales involved.

Summary: An increasing number of studies have shown that the assumption that rock fragments are inert with respect to water retention is incorrect, highlighting a gap in research. By developing new pedotransfer functions based on measurements from stony soils in New Zealand, it was possible to accurately predict the water content of these soils, demonstrating the importance of considering rock fragments in water retention models. The existing model, which did not account for the effects of rock fragments, performed poorly compared to the new models, indicating the need for more comprehensive models in soil water retention studies.

Summary: This study compared the impact of irrigating soils with raw wastewater and treated wastewater on earthworm communities in two natural meadows. The results showed that soils irrigated with raw wastewater had the highest earthworm density and species richness. The parameters of earthworm communities decreased significantly in soils irrigated with treated wastewater. These findings are important for understanding the relationship between soil pollution and earthworm biological activity.

Summary: The study found that irrigation with reclaimed water led to an increase in concentrations of trimethoprim and sulfamethoxazole in soil, while having significant effects on soil microbial abundance. Bacterial abundance increased significantly, but there was no significant effect on archaea abundance. The study highlighted the negative associations between the concentration of pharmaceuticals and personal care products in soil under reclaimed water irrigation and soil microbial abundance.

Summary: Water-saving through deficit irrigation management is an effective approach to improve water productivity in sustainable agriculture. Crop modeling can be used to evaluate the impact of different irrigation scenarios on yield and water productivity. This study assessed the effects of surface and sprinkler irrigation under different climatic scenarios and irrigation strategies. The results showed that reducing irrigation water by 30% improved water productivity in different growing seasons. Additionally, sprinkler irrigation can increase water productivity and sustain crop production in normal and wet years, but may have negative effects in other conditions. It is important to synchronize irrigation strategies with rainfall characteristics in areas with erratic rainfalls to enhance water productivity and maintain crop production.

Summary: Soil moisture has a direct impact on operational hydrology, food security, ecosystem services, and the climate system. However, its adoption has been slow due to inconsistent data collection and poor standardization. This paper attempts to establish a community-based standard of practice for in situ soil moisture sensors to provide consistent guidance for future research and applications.

Summary: The Gulf of Mexico Research Initiative (GOMRI) has conducted in-depth studies on the 2010 Deepwater Horizon oil spill from various perspectives and recently assessed the program's accomplishments. By compiling 330 published applications and focusing on modeling efforts, GOMRI has made significant advancements in integrating diverse disciplines and domains. Various modeling tools have been utilized, with a focus on circulation models coupled with other environmental factors to track the fate of oil and its impact on ecosystems and human health.

Summary: This study compared the effectiveness of a natural riparian system with a vegetated buffer strip and a constructed treatment system in receiving bunker silo effluent. The slag filter showed the greatest treatment efficacy, while passive treatment systems become P saturated over time, limiting their longterm P removal efficacy.

Summary: Wastewater utilization is an effective way to meet the water needs of plants and reduce environmental pollution. However, the study found that the effect of treated and magnetic wastewater on Manning roughness coefficient was not significant. The roughness coefficient showed a decreasing trend during the irrigation season.

Summary: Lateral subsurface flow (LSF) is a common phenomenon in the field, but limited observations have been made in undisturbed soils under controlled laboratory conditions. This study presents a method for extracting undisturbed soil samples and introduces an experimental setup for measuring and simulating LSF. The results show that the Richards equation and the van Genuchten-Mualem model can explain the water flow within the soil monolith.

Summary: The application of earthworm casts can effectively reduce soil salinity and sodicity by decreasing the salt content in the upper soil layers under brackish water irrigation. Additionally, earthworm casts improve soil structure and properties, inhibiting soil infiltration and evaporation, with effects increasing at higher application rates.

Summary: Chitosan nanoparticles (CNPs) with a size range of 68-77 nm were successfully synthesized through a simple and efficient method, using low molecular weight chitosan and tripolyphosphate as crosslinker. The CNPs showed monodispersity and high yield. Different purification methods and solution conditions were investigated and found to affect the size and polydispersity of CNP formation. The smaller CNPs synthesized using homogenization and filtration exhibited good interaction with negatively charged proteins and DNA, making them suitable for the development of virus surrogates for water applications.

Summary: Alginate nanoparticles (AlgNPs) were synthesized using ionic gelation and water-in-oil emulsification methods, with acid hydrolyzed and enzyme-digested alginate as starting materials. Small uniform AlgNPs (<200 nm) were obtained using ionic gelation method with optimal concentrations of alginate and CaCl2. The water-in-oil emulsification method resulted in lower dispersity of AlgNPs. Both methods are suitable for producing functionalized AlgNPs for various applications.
