Summary: In the last 30 years, severe soil acidification has been found in China due to acid deposition and nitrogen fertilizer overuse. Understanding the spatial pattern and vertical variations in base saturation percentage (BSP) and exchangeable cations (Ca2+, Mg2+, K+, Na+, H+ and Al3+) can directly benefit fertilization management and ecological protection.

Summary: Manure amendment has been proven effective in preventing or reversing soil acidification in red soil. However, an integrated approach combining manure with chemical fertilizers is needed to maintain soil productivity and nutrient balance, while reducing heavy metal accumulation and environmental risks. Incorporating 40% or more of total nitrogen from manure can help prevent acidification and provide necessary phosphorus, but additional potassium inputs are necessary for balanced plant nutrient supply.

Summary: The study investigated the effects of curing time and salinity on the water retention property and pore size distribution of lime-treated soil. The matric suction increased significantly with curing time, while the total suction varied slightly. Soil specimens with higher salinity exhibited higher matric and total suctions. The pore size distribution of lime-treated soil changed with time, shifting from bi-modal to tri-modal pattern and back to bi-modal due to clay shrinkage-related cracking. Lime treatment inhibited clay shrinkage, while the effects of curing time and salinity on microstructure were insignificant.

Summary: Soil acidification and base cation loss are significant problems in the subtropical red soil region of China, particularly in agroecosystems with high nitrogen fertilization. This study assessed the current status and future risk of soil acidification in a typical agricultural watershed using a two-year monitoring approach. The results showed that while significant soil acidification occurred, surface water acidification was minor, indicating the buffer capacity of the soils. However, there was a substantial loss of base cations, depleting the exchangeable pool in the watershed and posing a serious threat to soil recovery from acidification.

Summary: This study predicted soil salinity and sodicity through a 1:5 soil-water extract, showing positive correlations between EC values of saturation extract and 1:5 extract, exchangeable sodium percentage, and sodium adsorption ratio. Despite regional differences, strong correlations were observed, influenced by soil clay content, mineral composition, and salt content. The simplified evaluation method based on irrigation water composition can be useful for managing salt-affected soils in arid regions.

Summary: Chloride is a micronutrient necessary for plant growth, but long-term application of chlorinated fertilizers can introduce significant amounts of Cl- into farmland ecosystems. This study found that the long-term application of chlorinated fertilizer increased the Cl- content in the soil, reduced soil pH, cation exchange capacity, and exchangeable alkali ions, and increased the risk of aluminum toxicity. Additionally, the content of exchangeable calcium and magnesium ions in the soil was significantly reduced. Therefore, it is recommended to avoid long-term application of high chloride fertilizers in agricultural production.

Summary: Agricultural lime can improve the productivity of acid tropical soils, but the optimal lime rates are still uncertain in many tropical regions. To estimate lime rates, several lime requirement models based on soil data have been developed. In this study, we reviewed seven existing models and introduced a new model (LiTAS), and evaluated their accuracy in predicting lime requirements for different soil types. The foundational models targeting acidity saturation and base saturation were more accurate than the derived models, and the LiTAS model was the most accurate.

Summary: Through a meta-analysis of 53 grassland studies and a long-term field experiment, it was found that soil acidification was less pronounced when organic nitrogen (ON) inputs accounted for at least 20% of the total nitrogen input, especially at higher input rates. The rate of hydrogen ion (H+) production was mainly determined by NH3 volatilization from ON and the uptake of ON and NH4+ by Leymus chinensis, with the latter contributing less to H+ production. These findings suggest that the evaluation of N-induced soil acidification should consider N forms, and manipulating the relative composition of N inputs could be an effective approach to alleviate soil acidification.

Summary: High nitrogen input can lead to soil carbon limitation, eutrophication, deficiency of base cations, and accumulation of toxic micronutrients. Previous studies have primarily focused on the individual effects of carbon, macronutrients, base cations, and micronutrients on soil carbon mineralization. However, their relative importance in regulating soil carbon mineralization in nitrogen-enriched ecosystems remains unclear. This study examined the relative contributions of these factors in a grassland ecosystem and found that carbon availability was the most critical driver for carbon mineralization in nitrogen-enriched soil.

Summary: The study investigated the taxonomic structures and functional attributes of macrobenthic communities in the river Adige network in Northern Italy, testing the reliability of the River Continuum Concept (RCC) theory. The results showed a decrease in biodiversity levels along the river continuum, with corresponding loss in functional richness. The study confirmed the general validity of RCC in predicting macrobenthic community structures based on taxonomic diversity, although the functional analysis did not provide equally clear evidences.

Summary: The European eel is critically endangered and completes its life cycle between European freshwaters and the Sargasso Sea. The migration of glass eels into brackish waters is influenced by astronomical factors more than meteorological and oceanographical factors. Identifying the environmental variables affecting glass eels migration can help in promoting eel stocks restoration.

Summary: This study monitored and modeled the changes in hydraulic parameters induced by the introduction of graphene in different types of soil. The results showed that graphene had minimal effects on hydraulic conductivity, porosity, and effective porosity, but it significantly increased specific retention and altered dispersivity. However, using electrical conductivity for model fitting produced unreliable results.

Summary: Assessing the hydrogeochemical evolution of groundwater is challenging, especially considering the multiple impacts on its quality and the hydraulic interactions between aquifers. This study used hydrogeochemical modelling and data analysis to assess the complex hydrogeological regime, and found temporal-dependent behavior of the aquifer system during the irrigation period, leading to seasonal changes in hydrodynamic conditions and depletion of the upper aquifer layers. The proposed methodology proved to be a useful tool for capturing the temporal dynamics in complex groundwater systems and supporting groundwater resource management.

Summary: Machine learning algorithms are widely used for their high prediction accuracy, but they may produce overly optimistic results due to overfitting and inadvertent biases. Spatial data, with their intrinsic spatial autocorrelation, can introduce biases to machine learning. Spatial cross-validation (SCV) has emerged as a special resampling method to address this issue. This study compared the performance of SCV with conventional random cross-validation (CCV) in predicting groundwater electrical conductivity (EC) using different datasets. The results showed that SCV provides ML models with better generalization capabilities and reduces the over-optimism bias associated with CCV methods. SCV could be applied in studies that use spatial data and machine learning.

Summary: Thornthwaite's formula is widely considered as the best method for large-scale applications of potential evapotranspiration and aridity assessment. In this study, a global database of local correction coefficients for Thornthwaite's formula was developed to improve its accuracy by integrating local climatic factors. The validation using data from multiple stations showed that the corrected formula significantly improved the estimation of evapotranspiration and aridity indices in non-humid areas.
