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 ...
Using data from selected sites the proposed chart is evaluated by comparing with two CPTU-based classification methods as well as laboratory-based classification. The paper also discusses additional potential improvements that can be incorporated to the chart and more...
The pie chart represents the percentage of urban population considered in this study (1 billion approximately) in relation to the class of productivity of the soil on which they live; b) Classes of soil productivity of the fastest growing urban settlements. The SPI scale grouped by classes: ...
purposes these were omitted >800% between panelsa–land >3000% for panelsm–o. The class intervals of each continuous variable were obtained based on a natural breaks (Jenks) classification (20 classes). Each barplot (quantile distribution) represents the proportional number of sampling sites ...
Maps of the sub-Saharan African showing the sites from which soils were extracted for this study and pie chart representing the distribution of samples according to the sampled countries. Sampled sites in the map are represented by dots which are colored according to the country of origin ...
Soil colour is a key indicator of soil physical and chemical properties such as mineral composition, organic matter, and moisture content, and it is an important feature used in soil classification [1]. During field research of soil, scientists frequently carry a soil colour book, because colour...
Based on the functional classification by Gene Ontology (GO), most of these genes in crop mixture were specifically enriched for peroxidase activity (indicating oxidative stress) and flavonoid biosynthetic process (Fig. S6a; Supplementary Data 5). Using quantitative PCR (qPCR) of fifteen ...
