Summary: Iron oxides are highly reactive mineral phases in soils that significantly impact the dynamics of adsorbed elements and ecosystem services. Redox processes are the main mechanisms driving iron redistribution among soil volumes, while drainage-induced eluviation does not result in further iron isotope fractionations in soil volumes. Different mineral phases in soil volumes exhibit distinct iron isotope characteristics, with iron oxides having values close to 0 parts per thousand.

Summary: This is the first stage of a project to develop a dynamic modelling framework for catchment nutrient deposition from intensive agricultural practices. The focus is on nitrogen (N) as the specific nutrient of interest, introduced into the environment through livestock excrement. The first step involves modelling nutrient amounts at a field level and employing stochastic differential equations to describe the behavior of single and overlapping urine patches over time. Classical mathematical methods are used to solve the system, providing probability density functions, means, and covariances of the system variables.

Summary: The study analyzed the effect of surface-flow constructed wetlands (SFWs) on reducing nitrate-nitrogen (NO3--N) loads in the agricultural Warnow river basin in northeastern Germany. The results showed that SFWs could significantly reduce NO3--N loads in the entire basin, suggesting they are an important component of a comprehensive management strategy to reduce N loads in surface waters.

Summary: The changes in field crop traits due to genetic and agronomic improvements have significant implications for regional water quantity and quality processes. This study conducted a case study in the St. Joseph River Watershed in the U.S. Corn Belt, analyzing the sensitivities of crop traits to various water and nutrient-related factors. The results highlight the importance of considering crop improvements in long-term studies of hydrology and nutrient cycles in agricultural watersheds.

Summary: The study examines the role of artificial water bodies as indirect sources of agricultural N2O emissions, highlighting their different responses to N loading and the issue of overestimation in the current IPCC EF model. It calls for more extensive research on N processing in artificial waters and the inclusion of these systems in global N2O budgets.

Summary: The study showed that soil microbial composition remains stable over time and years, but varies significantly with topographic location, influenced by factors such as moisture, soil organic carbon, and pH. While microbial taxa often correlate with biogeochemical processes, there is a lack of ecological coherence among close relatives. Dominant phyla are consistent across the gradient, but specific members exhibit tradeoffs among locations, indicating a complex relationship between microbial composition and biogeochemical functions.

Summary: The study examines drainage design data from agricultural projects in southern Libya, using Artificial Neural Networks (ANNs) and Pedotransfer Function (PTFs) to predict saturated hydraulic conductivity (Ksat). Results show that ANNs provide more accurate predictions than PTFs, and can be successfully applied in data-poor areas for drainage system design.

Summary: Modelling is crucial in addressing scientific issues, including agriculture, as it provides a better understanding of empirical systems and aids in the design and improvement of new systems. Artificial neural networks and mathematical statistical methods are empirical mathematical models commonly used in these analyses. In agriculture, these models are employed to assess the quality of plant and animal production, pest risks, and agricultural environments.

Summary: The study utilized RBFNN models to predict the removal of COD in polluted water streams, with the PSO-trained model proving more accurate and efficient compared to the traditional model. Improving the removal ratio of COD to enhance drain water quality can help in reducing groundwater contamination and safeguard water resources in water-scarce countries like Egypt.

Summary: Biochar, produced through pyrolysis, is a crucial nanomaterial for wastewater treatment. This study uses a data-driven approach to model biochar production from agricultural wastes and finds that temperature, heating rate, residence time, and nitrogen flow rate significantly impact biochar yields. Support vector machine (SVM) and Gaussian process regression (GPR) models show potential for predicting biochar production, with GPR outperforming SVM. Artificial neural network-based algorithms provide even better prediction accuracy. Residence time during valorization reaction is identified as the most influential factor.

Summary: The fundamental processes for the biodeterioration of stone and metal involve similar microbially mediated reactions, but the differences lie in the nature of the substratum and the composition of the surroundings. Biofilms play a significant role in the deterioration of metals, while phototrophic organisms are important in the deterioration of stone. The reactions and time frames for failure are distinct for stone and metal structures.

Summary: Metal(loid) soil pollution is a significant environmental and health issue, requiring remediation through methods like phytoremediation. The use of amendments such as biochar and manure on contaminated soils can improve physicochemical properties and plant growth. A combination of biochar and manure appears to be the most effective treatment for enhancing soil fertility and promoting plant growth.

Summary: The study found that the hydraulic conductivity of organoclays with added surfactants increased by about two orders of magnitude in percolation experiments. These organoclays showed good adsorption capacity for the antibiotic AMX, but the increased permeability led to a shorter interaction time with the pharmaceutical, resulting in ineffective removal of the antibiotic.

Summary: Reclamation measurements are commonly used to reduce the leaching of metal pollutants, with recent experiments showing that adding ochre and manure can significantly decrease the leaching of metal pollutants, especially Pb. A multicomponent mixing model was developed to simulate and forecast the impact of amendments on leaching, providing insights into the biogeochemical processes involved in immobilizing metal pollutants.

Summary: This study evaluated the effect of phytostabilization on a Pb-rich mine waste through a laboratory pilot-scale experiment. The results showed that the addition of biochar, manure, and iron-oxide-rich ochre promoted plant growth and decreased Pb concentration in the surface layer pore water. Observations suggested that Pb immobilization in the rhizosphere occurred through the mechanical entrapment of tailing particles by Agrostis capillaris plants. Additionally, phytostabilization led to changes in microbial communities.

Summary: Dental microwear is a useful tool for studying the diet and dental evolution of mammals. However, the impact of exogenous mineral particles on dental wear is still a challenge. This study conducted a controlled-food experiment on wild boars to investigate the effects of soil ingestion on dental microwear. The results showed that soil ingestion resulted in less rough, simpler, and more anisotropic wear surfaces.

Summary: Soil characteristics are important for evaluating soil quality, health, and ecosystem services at the European scale. While some soil databases exist, individual European countries have a wealth of data that allows for more detailed assessment. Therefore, there is an urgent need to combine these data at the European scale.

A survey conducted in 2020 identified 170 soil databases in 24 European countries, with variations in parameters and methods. The harmonization of data and choosing suitable indicators for EU soil policy pose challenges due to these differences.
