Some of the methods use introduced, and not intrinsic, species. The benefit of this is a higher degree of standardisation, as the species used in these bioassays is easy to maintain in laboratory cultures compared to naturally occurring species. The drawback may be that their ecological ...

Highly developed laboratory methods of soil chemical and biological analyses are existing, but screening methods that work under field conditions are comparatively rare. Biological soil degradation needs further evidence-based research and high-precision data for understanding and combating processes. Crucial...
The soil properties were measured according to methods in the Kellogg Soil Survey Laboratory Methods Manual [60]. The percentage of SOC was calculated from the difference of percent total carbon by combustion (Procedure Code: 4H2a) and calcium carbonate equivalent by hydrochloric acid dissolution with...
