For a hazard classification of soils or a ranking of soils this may not be so important. However, to evaluate potential risk-reduction measures or risk management procedures it may be important to identify the most problematic substances. A comparison of soil screening values with measured ...
The plant association and vegetation mapping studies are used to delineate land management units with respect to ecological condition and potential for enhancement byrevegetation. An association is a unit of classification that defines a particular plant community, and generally has a consistentfloristiccom...
We found a significant difference between treatment and control metabolomes at this metabolite classification level (Additional File 7 Fig. 5 and Table 2). Specifically, all exudate-treated microcosms were significantly enriched for lipids, benzenoids, alkaloids and derivatives, and organoheterocyclic ...
TheC-factor is closely related to the types of vegetation and crops25; therefore, the values of theC-factor in arable and non-arable land in China were calculated separately. Some adjustments were made to the classification of crop types and the referenceC-values of these crop types in arabl...

Two major measurements are used for soil classifications, i.e., particle size distribution (gradation curve) and plasticity chart of Casagrande (1948) (Atterberg limits), which have been covered in detail in soil mechanics textbooks. Among various soil classification approaches, the USCS (Unified S...
