  Stable Soil Biota Networks Are Beneficial for Improving Soil Ecosystem Function, Study

  A researcher team led by Prof. WANG Kelin from the Institute of Subtropical Agriculture of the Chinese Academy of Sciences conducted a regional scale sampling in a karst region in southern China. Recently, they have revealed how intensive agriculture affects the complexity and stability of soil biota networks, and how these effects are linked to soil functions. Their study was published in Global Change Biology on January 22.

  Sediment Hardening Effect Obviously on Submerged Plants in Dongting Lake Area

  A research team led by Professor Xie Yonghong from the Institute of Subtropical Agriculture, Chinese Academy of Sciences, conducted field investigations and controlled experiments to analyze the characteristics of sediment hardening and its impacts on the growth of submerged plants. At the time, they explored various sediment remediation measures to promote the growth of submerged vegetation. Their new findings were recently published in Plant and soil and Frontiers in Plant Science.

  Simultaneous Reduction Cadmium and Arsenic accumulation in Rice Grains by EDTA·Na2Fe

  Cadmium (Cd) and arsenic (As), the two main inorganic pollutants in arable land in China, have strong biological toxicity and soil availability. It is easy to accumulate in rice (Oryza sativa L.) and affect health after entering the human body through the food chain. Iron fertilizer has been widely used to reduce Cd content in rice. Compared with inorganic iron fertilizer, chelated iron fertilizer has a better effect on reducing Cd accumulation in rice.

  New Insights Into the Trade-Off Between Soil Organic Carbon Formation and Stability

  Soil organic carbon (SOC) is the largest carbon pool in terrestrial ecosystems, playing a vital role in climate regulation and ecosystem sustainability. Microbial carbon use efficiency (CUE) refers to the proportion of assimilated carbon retained in microbial biomass. High CUE promotes SOC formation by driving microbial growth and the production of necromass through microbial death. Meanwhile, the stabilization of microbial necromass by soil aggregates and minerals enhances SOC stability. Thus, SOC accumulation involves two fundamental processes: SOC formation and stability.

  Human Disturbance Intensified the Erosion and Sediment Production of Karst Depressions During the Historical Period, New Study

  Recently, the research team led by Prof. Wang Kelin from the Institute of Subtropical Agriculture, Chinese Academy of Sciences pioneeringly analyze the surface process and the causes of human disturbance in the watershed in the historical period based on the filling process in karst depression and the historical environmental information of sediment. An important progress was made in the impact of human disturbance on soil erosion in the karst region of southwest China during the historical period.

  How the Rock Plant Absorb Rock Moisture to Maintain Transpiration

  In the previous studies, Prof. Chen Hongsong from the Institute of Subtropical Agriculture of Chinese Academy of Sciences, led the team to found that some plants in the soil-dominated habitat (called soil plants) usually preferred to absorb the shallow layer water, while in the rock-dominated habitat others (called rock plants) could rely on deep layer water to alleviate water stress. “Now, we try to quantified the effects of soil and epikarst water on transpiration based on the physiological characteristics of root and leaf in karst region in southwest China.” Prof. Chen said.

  Precipitation Sensitivity Thresholds Clarified for Vegetation Growth in Karst

  Large-scale ecological projects have significantly “greened” the karst region in Southwest China over the past 20 years. However, the fragile geological setting, the frequent occurrence of extreme droughts in recent years, in the context of global climate change, has increased uncertainty and risk in the recovery and growth of vegetation.

  Researchers Separated the Key Factors Influencing Runoff and Sediment Yield Changes in Different Karst Watersheds

  Recently, researchers led by Prof. Kelin WANG from the Institute of Subtropical Agriculture, Chinese Academy of Sciences, demonstrated that the spatial variation and controlling factors of runoff and sediment yield (SY) in different karst watersheds were quantitatively analyzed.
