  • In order to estimate the future trends of the atmospheric levels of various greenhouse gases, and to plan carbon emission trade, it is essential to measure the carbon dioxide concentration values all over the world. In this paper the AA. analyse
  • the carbon balance of the atmospheric-biosphere system, and the potential effects of global warning. - (AM)

  • Effects of microbiotic crusts under cropland in temperate environments on soil erodibility during concentrated flow
  • To study the effect of microbiotic soil crusts on soil erosion resistance of loess-derived soils under cropland during concentrated runoff, two study areas in central Belgium were selected in the vicinity of the cities of Leuven and Sint-Truiden
  • . The soils in both areas developed on the loess that covers Tertiary sandy deposits. Three stages of microbiotic crust development on cropland soils are distinguished. The results suggest that the possible magnitude of the microbiotic soil crust effect
  • is not negligible compared with the effect of vegetation ground cover. Microbiotic crusts thus help conserve soils.
