Summary: In the past decade, biochar has been widely recognized as an effective soil conditioner for controlling soil acidification and mitigating Al toxicity. This study investigated the potential of rice-straw hydrochar (HC) as an economical carbon material for alleviating Al toxicity in acidic red soils. The results showed that the addition of hydrochar significantly stimulated root growth, reduced cell death ratio and Al content in root tips, and decreased total Al content and the proportion of Al3+ species in the soil solution. Hydrochar mainly mitigated Al toxicity through Al-DOC complexation and adsorption. The overall alleviation effect of hydrochar on Al toxicity was lower than that of pyrochar, but it still shows potential as an economical soil amendment.

Summary: Forest soil acidification caused by acid deposition poses a serious threat to the forest ecosystem. A three-year field experiment in Southern China showed that the surface application of biomass ash and alkaline slag significantly increased soil pH, reduced exchangeable acidity and active Al, and increased exchangeable Ca2+ and Mg2+ in the topsoil. Alkaline slag was more effective than biomass ash in ameliorating soil acidity and alleviating soil Al toxicity in the subsoil.

Summary: The study aimed to investigate the combined effects of organic manure and nitrification inhibitor on nitrogen transformation, nitrous oxide emissions, and gene abundance of ammonia oxidizers in acidic and alkaline soils. The results demonstrated that the addition of nitrapyrin along with organic amendment effectively reduced N2O emissions and improved N recovery and utilization in both types of soils. Nitrapyrin significantly inhibited the gene abundance of ammonia-oxidizing bacteria in alkaline soil and inhibited the growth of ammonia-oxidizing archaea in acidic soil.

Summary: The study indicates that the interaction between zinc oxide nanoparticles(ZnO NPs) and phosphorus(P) levels significantly affects the bacterial community and functioning of periphytic biofilms. Under P-limited conditions, ZnO NPs lead to a decrease in alkaline phosphatase activity(APA) and reduced network complexity among bacterial taxa, whereas the opposite trend is observed under P-replete conditions. Correlation analysis and random forest modeling suggest that excessive Zn2+ release and high reactive oxygen species (ROS) production are main factors inhibiting APA under P-limited conditions, while adjustment of bacterial diversity and enhancement of cooperation among keystone taxa help to maintain APA in P-replete conditions.

Summary: Overfertilization is common in rainfed apple orchards on China's Loess Plateau, but its impacts on soil physicochemical properties in deep soil profiles are poorly understood. This study found that different land-use types showed divergent distribution patterns in soil properties, with low variability for SWC and pH, moderate variability for NH4+-N, AP, and AK, and high variability for SOC, NO3--N, and EC. The results also showed that fertilization influenced soil water content, NO3--N, AP, and AK, and NO3--N played a crucial role in regulating pH and EC. Soil profiles were useful for studying the evolution of soil quality.

Summary: The Mediterranean region is expected to experience more intense rainfall events and severe droughts due to climate change, leading to an increase in runoff and erosion rates in agrosystems. Vegetation cover can help reduce erosion and the soil seed bank can provide cost-effective vegetation. This study assessed the effect of vegetation cover on seed loss in vineyards and evaluated the differences in the soil seed bank along a transect. The results suggest that vegetation may not protect interrows from runoff-induced seed loss.

Summary: This research introduces a hybrid four-sub-deep neural network (HFSD) model for partitioning NEE into GPP and ER. The HFSD employs dual sub-deep neural networks to estimate ERa and ERb and incorporates GPP and environmental variables to predict vegetation transpiration. The results of the model show that the dual sub-DNNs architecture enhances the accuracy of ER simulations, while using EC-derived T as a constraint improves the accuracy of GPP simulations. Correlation analyses suggest that solar radiation and air temperature primarily influence the seasonal variations in GPP and ER, while soil moisture has a strong impact during dry seasons. This study advances the biophysical description of data-driven models for NEE partitioning and enhances the accuracy of GPP and ER estimates.

Summary: This study investigated changes in vascular plant species in Central European arable fields and their edges from 1930 to 2019. The results showed a small decline in overall species occupancy, but a more pronounced species turnover. Species with environmental preferences for nutrient-rich sites with neutral pH increased in occupancy, while species typical for arable fields decreased. No response to climate change was observed, and there was a decrease in archaeophytes and native species and an increase in neophytes.

Summary: Proper bed substrate selection is crucial for the performance of constructed wetlands, especially when treating drainage water with high nitrogen and low carbon and phosphorus concentrations. In a field-scale pilot plant, adding a carbon-rich substrate such as soil or biochar increased phosphorus availability in beds. Beds with soil displayed higher microbial density and activity, as well as better plant growth compared to gravel. These findings highlight the importance of selecting suitable substrates for treating irrigated agricultural water.

Summary: Considerable advances have been made in the assessment and mapping of soil organic carbon stocks. However, the rates of change in carbon stocks are influenced by various factors and need to be quantified. This study found that sandy soils under cultivation and forests have different organic carbon stocks. Factors such as tillage, irrigation, and nitrogen applications contribute to the decline in soil organic carbon stocks. Afforestation of abandoned cultivated fields can increase soil organic carbon, but it is still lower than soils under forest that have never been cultivated.

Summary: Grazing exclusion is a widely implemented strategy for restoring degraded grassland ecosystems and increasing carbon stocks. This study analyzed data from 199 experiments to understand the temporal responses and factors influencing plant and soil carbon stocks following grazing exclusion in different grassland ecosystems. The results showed that plant biomass carbon stocks and soil organic carbon stocks decreased exponentially or rationally with years since enclosure. Grazing exclusion had positive effects on aboveground biomass carbon, but the effects on belowground biomass and soil carbon were influenced by climate, initial carbon levels, and grazing exclusion duration. The response of carbon stocks to grazing exclusion stabilized after approximately 40 years, with soil carbon sequestration showing a lagged pattern compared to plant biomass carbon. The study highlighted the effectiveness of grazing exclusion in regions with low carbon content and non-water limited conditions. However, it might not be an effective measure to increase soil organic carbon stocks in water-limited areas like desert grasslands.
