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 found that at low boron supply, plants fed with nitrate and ammonium had similar B-10 uptake rates, accumulation, and xylem B-10 concentrations, but these attributes were reduced at high boron supply. Ammonium-induced acidity and nitrate-induced alkalinization led to altered B distribution between roots and shoots as well as different B transport mechanisms in plants.

Summary: This study in the Czech Republic focused on the changes in element fluxes in semi-natural forest ecosystems and their relationship with anthropogenic acidification recovery, finding reductions in sulphur and nitrogen deposition. Changes in stream chemistry were influenced by nitrogen and sulphur deposition, with soils acting as a net source of sulphur in most catchments. Stream nitrate concentration decreased more than nitrogen deposition, and was closely related to the stream dissolved nitrogen to phosphorus ratio.

Summary: Climate directly and indirectly controls forest biomass production through effects on cambial activity, CO2, air pollution, and nutrient availability. The increase in intrinsic water use efficiency (iWUE) since the 1950s has positively affected tree growth, with contributions from both climate and SN deposition trends. In Central Europe, the steep increase in iWUE of conifers in the 20th century can be explained by SN pollution in addition to other factors.

Summary: Chronic nitrogen inputs can have both positive and negative effects on forests. This study examines the complexity of the nitrogen cycle and integrates soil delta N-15, ecosystem N losses, and soil microbiome functional gene potential to explore indicators for nitrogen cycle openness. The results show that soil delta N-15 is associated with N losses and scales with the abundance of soil bacteria. Genes related to ammonia oxidation and nitrate reduction are found to be more informative than those linked to N2O production in explaining the variability in soil delta N-15.

Summary: Forest areas in Europe and North America are experiencing an increase in insect infestations due to accelerated climate change. A study on the mass budget of major elements in the ecosystems of two catchments revealed the impact of tree dieback and long-term accumulation/losses. The outbreak of bark beetles resulted in high tree mortality in one catchment, significantly affecting the forest. This disturbance led to increased element losses and transformed the impacted catchment into a net carbon source.

Summary: This study investigated the inflows and outflows of eight acidified glacial lakes in the Bohemian Forest, Czech Republic and Germany, and examined the impact of these lakes on water chemistry and macroinvertebrate assemblages in headwater streams. The results showed that lakes can alter water chemistry and the composition of macroinvertebrate communities. The morphometry of lakes was found to be related to the levels of dissolved nutrients and ammonia nitrogen, but other physico-chemical parameters showed no significant relationship with lake morphometry. Comparisons of macroinvertebrate groups revealed differences in composition between inflows and outflows. pH was found to be positively correlated with the number of macroinvertebrate taxa in inflows, but not in outflows.

Summary: This study investigates the effect of cation exchange resin (CER) on the sequential recovery of hydrogen and methane from anaerobic digestion (AD) and the corresponding mechanisms. The results show that CER can simultaneously enhance the production of hydrogen and methane by promoting the solubilisation, hydrolysis, and acidification of organic matter. Additionally, CER facilitates effective contact between bacteria and organic particulates and reduces the energy barrier for mass transfer during methane production. The study also reveals changes in the microbial community structure and metagenomics during the AD process.

Summary: The fouling of seawater reverse osmosis membranes is a persistent challenge in desalination. This study monitored the operational performance of a desalination plant for 7 years and the fouling development in different areas of membrane modules. The findings showed that operational performance declined over time and fouling mainly occurred at the feed side of the modules, with the highest microbial diversity. Keystone species like Chloroflexi and Planctomycetes played an important role in maintaining community structure and biofilm maturation. Polysaccharides, soluble microbial products, marine humic acid-like substances, and inorganic substances contributed to fouling. Overall, biofouling had a significant impact on membrane fouling after 7 years of operation.

Summary: By synergizing organic carbon source, thiosulfate, and zero-valent iron, efficient mixotrophic denitrification of oligotrophic secondary effluent can be achieved. Thiosulfate plays a vital role in promoting TN removal efficiency, while corrosion of Fe0 releases OH- to neutralize H+ from thiosulfate-driven denitrification, creating a suitable environment for denitrification. The coordination of thiosulfate and Fe0 maintains the dominance of Thiobacillus for denitrification.
