  Cropland conversion impacts on microbial resource limitation in karst soil

  In a paper in Geoderma, researchers in the Institute of Subtropical Agriculture, Chinese Academy of Sciences (ISA) studied three common cropland conversion strategies in a karst area of southwest China (i.e., conversion with i) Toona sinensis (TS), ii) Guimu-1 hybrid elephant grass (GG), and iii) a combination of Zenia insignis and Guimu-1 hybrid elephant grass (ZG) using cropland (CR) with maize-soybean rotation as reference. Enzymatic stoichiometry was calculated and used as an indicator of microbial resource limitation.

• HMB prevents obesity via gut microbiota

  Recently, a team of researchers from China Agricultural University, the Institute of Subtropical Agriculture, Chinese Academy of Sciences (ISA) conducted a study to compare and contrast the effects of different dosages of HMB on lipid metabolism in a high-fat diet (HFD)-fed mice and unravel the underlying mechanisms of HMB action of lipid metabolism.

• Biological Soil Crusts Modulate Soil Nitrogen Following Vegetation Restoration in Subtropical Karst Region

  To address the above uncertainties, researchers from the Institute of Subtropical Agriculture (ISA) of the Chinese Academy of Sciences measured the physical and chemical characteristics of the biocrusts and underlying soils, as well as litter properties under different vegetation restoration strategies (i.e., restoration with plantation forest, forage grass, and a combination of forest and grass, and spontaneous regeneration to natural grassland) following cropland abandonment in a subtropical karst region, southwest China.

  Scientists Discover Labile Carbon Matters More Than Temperature for Enzyme Activity in Paddy Soil

  The research team led by Prof. WU Jinshui from the Institute of Subtropical Agriculture (ISA) of the Chinese Academy of Sciences recently reported that enzyme activities are more sensitive to C addition than to temperature in paddy soil and SOM decomposition is accelerated by both C input and warming, especially at low temperatures.

• Can Exogenous Nitrogen Inputs Impact on Mycorrhiza in Karst Grassland?

  The simulated N deposition experiment (N, 100 kg N ha-1 yr-1; P, 50 kg P ha-1 yr-1; NP, 100 kg N ha-1 yr-1 + 50 kg P ha-1 yr-1) and different legume species (Amorpha fruticose vs Indigofera atropurpurea) or planting densities (1.5 × 2 vs 1 × 1 m) in the grassland were set up at the Institute of subtropical agricultural (ISA) of the Chinese Academy of Science (CAS). Researchers measured the AMF abundance and community composition, as well as soil properties.
