The objectives of this study were to evaluate the restorative effects of re-vegetation and vegetation type on soil enzyme activities and microbial functional diversity of eroded red soil. Soil samples were collected by horizon from eroded soils that had been restored for 18years with Cinnamomum camphora, Pinus massoniana or Lespedeza bicolor. Un-eroded soils planted with these vegetation types and...
Agricultural soil pollution is a serious problem that can endanger ecology, food safety, and human health. The study evaluated the accumulation and distribution of major and trace elements in the agricultural soil of the Gannan area in the northwest Songnen-Plain, a very important base of grain production in northeastern China. To identify the concentrations and sources of pollutants and also to assess...
Lhasa is a crucial agricultural region of the Tibetan plateau for local grain and vegetable supplies. Therefore, to sustain soil productivity, it is important to understand how agricultural management practices can cause changes in soil properties. Based on the information from the soil survey conducted in the late 1980s, we selected and sampled the following sites in the summer of 2007: 17 sites...
The objectives of the study were to identify principal hydrological pathways and source areas of N and P losses by multi-scale monitoring and to estimate total nutrient losses from the catchment. An agricultural catchment with rain-fed agriculture and irrigated paddy fields in subtropical China was monitored with regularly sampling, together with intensive sampling during and after rain storms. Regular...
The clayey Ultisols in low hilly area in southeastern China were called for agricultural reclamation to meet the increasing food demand. However, little attention was given to soil erosion during land use planning due to lack of information on the amount of soil erosion and how to restore the severely eroded bare soils. The objectives were to estimate the long-term influences of reforestation on soil...
