  Scientists Found Eco-strategies of Soil Microbes Control Temperature Sensitivity of Organic Matter Decomposition

  To test this hypothesis, Dr. Hui Li and her colleagues from the research group of Soil Chemistry in Institute of Applied Ecology, CAS analyzed Q10 of SOM decomposition in 13 sites of natural temperate mixed forests along a mean annual temperature (MAT) gradient of -1.9 to 5.1 °C.

• Fatty Acid Methyl Ester-based Microemulsion Effectively Increases the Polycyclic Aromatic Hydrocarbon (PAH) Removals in Soils

  In a study published in Journal of Hazardous Materials, a research group led by GONG Zongqiang from the Shenyang Institute of Applied Ecology of the Chinese Academy of Sciences (CAS) proposed a fatty acid methyl ester-based microemulsion to remediate polycyclic aromatic hydrocarbon (PAH) contaminated soils.

  Scientists Have Series of Discoveries on Soil Microbial Carbon Pump and Carbon Storage Mechanism

  The mechanism of soil carbon turnover and sequestration is a hot and difficult point in carbon biogeochemical cycling research. The improvement of soil carbon sink function is closely related to key issues such as food security, water body quality, biodiversity maintenance, land health conservation (e.g., the black soil protection in particular), the international development strategy of Carbon Neutrality, and global climate crisis.

• Researchers Reveal How Nitrogen and Water Addition Influence Inorganic Phosphorus Components in the Soil of Semi-arid Grasslands

  Phosphorus is a limiting nutrient affecting the primary productivity of terrestrial ecosystems. In semi-arid grasslands, soil phosphorus mainly exists in the form of mineral-bound inorganic phosphorus (up to 75% of total phosphorus in calcium-rich soil), which is an important soil phosphorus pool but is difficult to be directly used by plants.

• How Do Aggregates of Different Sizes Mediate Soil-Plant Relationship?

  The researchers (Associate Prof. Wang Ruzhen, Prof. Jiang Yong and Ph.D. student WU Hui) found that there was a significant correlation between plant characteristics (biomass and species richness) and macro-aggregate properties (ratio of available nutrients to eubacteria) under the nitrogen addition and mowing treatment.

  Assessment of the Spatial Ecological Risk and Human Health Risk for Contaminated Soil in Oiled Fields

  Soil total petroleum hydrocarbon (TPH) and Polycyclic aromatic hydrocarbons (PAHs) pollution in oiled fields is a worldwide environmental problem. Accumulation of TPHs and PAHs in the soils was led by the crude oil exploitation. It caused the spatial ecological risk and human health risk.

  Critical Minority of Large-diameter Trees Are More Important than Plant Diversity for Driving Forest Dynamics

  Large old trees are keystone structures in forests, woodlands, savannas, agricultural landscapes, and urban areas, and play unique ecological roles not provided by younger, smaller trees.
