  Chemical Fertilization Affects N and P Runoff Losses from Paddy Fields

  By designing the interaction treatments with different chemical fertilizers (0%, 50%, 70%, 100% and 150% of conventional dosage) and pesticides (0%, 50%, 70% and 100% of conventional dosage), researchers from the Institute of Subtropical Agriculture (ISA) of the Chinese Academy of Sciences (CAS) observed ponding water N and P concentrations and N and P runoff losses with high-frequency in three rice seasons in the double rice-cropping paddy fields in hilly areas in South China.

  Effects of Organic Inputs on Microbial Carbon Use Efficiency and Necromass Accumulation in Paddy Soils Revealed

  The researchers from the Instituted of Subtropical Agriculture (ISA) of the Chinese Academy of Sciences examined the microbial CUE, microbial biomass turnover, and necromass accumulation in rice rhizosphere and bulk soils subjected to long-term (31 years) fertilizations. Five fertilization treatments were included: no fertilizers, mineral fertilizers alone, mineral fertilizers plus rice straw incorporation, and mineral fertilizer combined with a low or a high amount of organic manure.

  Forest Management in Southern China Generates Short Term Extensive Carbon Sequestration

  Recently, researchers from the Institute of Subtropical Agriculture (ISA) of Chinese Academy of Sciences, University of Copenhagen (Denmark), CREAF (Spain), INRA, Institute Pierre Simon Laplace (both France), the University of Oklahoma, the Institute of Remote Sensing and Digital Earth (China) and other universities identified different forest and land management strategies as well as their biomass carbon sinks from 2002 to 2017 in southern China by combing optical and low frequency passive microwaves satellite data. They also evaluated soil moisture trends from 2010 to 2017 for this area.

• HMB is Required for Leucine to Inhibit Muscle Protein Degradation

  Using a starvation model, a team of researchers from China Agricultural University and the Institute of Subtropical Agriculture (ISA) of the Chinese Academy of Sciences found that HMB (50 μM) is more superior than leucine (0.5 mM) in effectively suppressing protein degradation of C2C12 myotubes. However, it remains unknown whether HMB mediates the inhibitory effects of leucine on protein degradation, and whether the protective effect of HMB is still more effective than that of leucine when its treatment concentration is fay beyond physiological limits.

  Fertilization Effects on Microbial Resource Limitation in Karst Soil

  Researchers in the Institute of Subtropical Agriculture, Chinese Academy of Sciences (ISA) investigated the effects of long-term (11 years) fertilization on microbial resource limitation in a karst cropland under maize–soybean rotation. Soil microbial resource limitation was assessed using enzymatic stoichiometry.

• Landscape and livestock planning simultaneously effectively improve water quality

  Based on the monitored riverine water flux and observed riverine P levels and loadings, and statistical data, through the partial least squares regression (PLSR) technique, a team of researchers from the Institute of Subtropical Agriculture, Chinese Academy of Sciences (ISA) investigated the major natural and anthropogenic determinants of riverine P in one forest and ten agricultural catchments in subtropical China during 2011 to 2017.

• Topography Modulates Effects of Nitrogen Deposition on Asymbiotic N2 Fixation in Soil but not Litter or Moss in a Secondary Karst Forest

  Recently, in order to assess how ANF in soil, litter and moss responds to N addition, and whether topography modulates the responses of ANF in soil, litter or moss to N addition, a research team led by researcher LI Dejun at the Institute of Subtropical Agriculture, Chinese Academy of Sciences (ISA) conducted an N addition experiment at two topographic positions, i.e., valley and slope of a secondary karst forest in southwest China.
