| There are six major aspects of technical difficulties for soil quality survey: 1) accurate measurement of of soil fungal and bacterial biomass carbon; 2) rapid measurement of the number and biomass of various functional groups of soil animals; 3) castigation/revision of the physiological parameters for the soil food web model; 4) the in situ measurement of the respiratory intensity of soil biota; 5) the inter-conversions among soil organic carbon fractions measured by various physical, chemical and biological methods; 6) establishment of the soil organic carbon model driven by microbial functional groups. For the solutions, possible technical routes were proposed. |
