Summary: This study investigated the influence of biochar on soil content, enzymatic activity, and fungal community diversity and structural composition through a soil column leaching simulation experiment. The results showed that biochar increased the pH value and the contents of soil organic matter, total nitrogen, available phosphorus, and available potassium, but reduced the microbial biomass carbon and microbial biomass nitrogen. Biochar also affected enzymatic activity and the diversity and structure of the fungal community. Furthermore, biochar inhibited the growth of harmful pathogens and increased the abundance of beneficial fungi in soil.

Summary: Limited research supports local nutrient management decisions in North Carolina grape production. Late season foliar nitrogen application increases nitrogen concentration in grapes, and smaller split nitrogen applications are more effective in increasing yeast assimilable nitrogen. Monitoring petiole phosphorus and potassium levels accurately assesses plant nutrient status and informs nutrient management decisions.

Summary: This study evaluated the declining soil quality and microecological imbalances in larch plantations and proposed mixed coniferous and broad-leaved plantations as a potential solution. The results showed that bacteria had a stronger spatial dependence than fungi, and plantation types significantly affected the fungal community. Increasing soil depth led to significant increases in the relative abundance of Gaiellaceae and bacterial ligninolysis and nitrogen cycling functions. Compared to other plantations, the Larix plantation had a significantly higher relative abundance of Inocybaceae. Soil available phosphorus variations were closely related to the relative abundances of Gaiellaceae in different soil depths and Inocybaceae in different plantation types. These findings suggest that fungal community changes should be considered in the sustainable management of mixed plantations.

Summary: Lake drying is a significant issue caused by water management failures and exacerbated by climate change. The drying up of Lake Urmia in Iran has dire consequences for the region, affecting food production and potentially leading to unknown impacts. Through studying changes in climatic conditions, land use, and land degradation, it has been found that the drought has significantly reduced food production in the past three decades and is projected to further decrease in the future. This study emphasizes the importance of addressing environmental impacts and supporting food production in regions with dying lakes.

Summary: The Quaternary red soil profiles under different land-use patterns in Chaoyang City, China were studied to understand the nutrient changes. The results showed variations in nitrogen, phosphorus, and potassium contents, which were related to vegetation type, coverage rate, and fertilization method. The sparse forest-grassland was found to have good sand fixation, soil and water conservation properties, leading to increased nutrient content in the Quaternary red soil.

Summary: This article introduces an observation-based methodology to capture evidence of global terrestrial ecosystem changes and attribute them to natural or human activities. The authors use satellite data to construct maps of changes in soil and vegetation water content and biomass, and combine them with land cover change, vegetation greenness, and precipitation variability to assess their relationship with major documented ecosystem changes. The results reveal patterns of change in different regions and classify them according to human activity drivers.

Summary: Research shows that maize is more sensitive to topsoil thinning, possibly due to reduced soil nutrient availability and its capability to extract nutrients. Additionally, the greater stimulation of nutrient mineralization processes in shallow topsoil conditions did not alleviate the nutrient constraint to maize yield.

Summary: Soil erosion and surface pollution near reservoirs can negatively impact water quality and safety. This study focused on the land around the Shitoukoumen Reservoir in China to investigate the factors influencing soil aggregate stability. The research found that land use type, soil properties (such as organic matter, pH, and clay content), and environmental factors (especially temperature) significantly affect soil aggregate stability. The study suggests the need to convert upland areas into paddy fields, increase forest land, and apply organic fertilizers to improve soil quality in the future.

Summary: Microbial-mediated iron oxidation and reduction play a significant role in the biogeochemistry and mineralogy of ecosystems, but the composition and distribution patterns of iron redox cycling bacteria in peatlands are still poorly understood. This study used high-throughput sequencing to compare the biogeographic patterns of iron redox cycling bacterial communities in soil and water samples from different types of peatlands in Northeast China. The results showed that these bacteria are influenced by pH, dissolved organic carbon, and iron concentrations, and exhibit different distribution and assembly mechanisms between soil and water, with soil communities being more affected by geographic distance.

Summary: Snow is an important form of water storage in alpine watersheds, playing a crucial role in regional water balance. This study evaluated the contribution of snowmelt water to runoff in the Erdaobaihe River watershed of Changbai Mountains area, showing that snowmelt water contributes significantly to the total runoff. With climate change leading to shortened snowfall periods and increased extreme snowfall events in the region, these findings will be valuable for future water management strategies in alpine watersheds.

Summary: Iron oxides promote carbon store stability, but may also contribute to carbon decomposition at redox interfaces. Agricultural peatlands have higher levels of reactive and short-range-order iron, with high ferrous iron countering the role of iron-sorbed carbon complexes. Iron reduction can initiate a cascade effect on carbon mineralization and mobilize dissolved organic carbon in flooded agricultural peatlands.

Summary: Marshes in high plateaus play a critical role in governing the carbon cycle due to their large yet unstable soil organic carbon (SOC) storage. The Yarlung Zangbo River (YZR) is the world's highest river, and it harbors widespread alpine marshes and meadows with huge SOC storage but high vulnerability to climate change. This study systematically evaluated the effects of environmental factors on SOC storage along the YZR and found that climate, plant biomass, soil nutrients, and molecular features of organic matter all have significant impacts. The findings suggest that rising temperatures and decreased precipitation relative to temperature could have adverse effects on SOC storage in the future.

Summary: More than half of the Earth's wetlands have been converted for agriculture, resulting in instability and leaching risks of soil phosphorus (P). This study evaluated the effects of agricultural land use on soil P stability by investigating the long-term impacts of wetland cultivation for rice and soybean in Northeast China. The results showed that soybean cultivation decreased total P content, while rice cultivation did not have a significant impact. Both soybean and rice cultivations increased labile and moderately labile inorganic/organic P fractions. Various factors, such as pH, Fe minerals, and organic carbon, were found to influence P fractions during soybean and rice cultivation.

Summary: Harmful cyanobacterial blooms have negative effects on the diversity and composition of metazooplankton, reducing species diversity but increasing biomass, functional dispersion, and functional evenness. Cyanobacteria have different effects on metazooplankton biodiversity and functional diversity during bloom and non-bloom periods. Physicochemical variables, temporal variation, and cyanobacteria explain a significant portion of the variation in metazooplankton, with cyanobacteria having a greater impact during the bloom period. Understanding the impact of cyanobacterial blooms on metazooplankton communities can enhance ecosystem restoration and eutrophication management.

Summary: The sprouting and early growth of wetland plants in China can be inhibited by freeze-thaw cycles, which reduce soil nitrogen through denitrification. Experimental results suggest that these cycles are an important abiotic stress on plants in mid-to-high latitudes during the beginning of winter and spring. Flooding in wetlands can alleviate the medium-term effects of freeze-thaw cycles.
