In addition to these plant essential microelements, human beings and animals require chromium (Cr), iodine (I) and selenium (Se). Microelements are used in relatively small amounts and constitute less than 0.1% of dry plant tissue. Some of the microelements may be toxic when consumed at ...

1). Notably, from a human health perspective all these different urban green components vary greatly with the intensity and style of urban development, which also needs closer attention and consideration. For example, green roofs can provide habitat for many soil animals by providing suitable ...
Anthropogenic reductions in soil health, and of individual components of soil quality, are a pressing ecological concern. A conference entitled ‘Soil Health: Managing the Biological Component of Soil Quality’ was held was held in the USA in November 1998 to help increase awareness of the ...
Contamination is often preferentially present in the finer or coarser fraction of the soil or the organic components (ex. humus), contamination can therefore, be removed in some cases using a process which separates the soil into fractions on the basis of specific gravity or particle size or ...
Plants respond to nutrient deficiency by altering root morphology, recruiting the help of microorganisms and changing the chemical environment of the rhizosphere. Components in root exudates assist plants in accessing nutrients by acidifying or changing theredoxconditions within the rhizosphere or directlyche...
Nevertheless, F:B ratios are supposed to be dependent on the quality of organic inputs, fungi being more dominant when inputs are more recalcitrant because of their better capability to degrade lignin and other plant cell wall components (Strickland and Rousk2010). For this reason, the C:N ...
In vitro protocols that utilize organic physiological components and temperatures that are consistent with the human gastrointestinal tract (37°C), such as the IVG protocol, were found to produce higher mercury bioaccessibility results when compared to simplified protocols such as the CDM (Camp ...
The results of PCA showed that four components were extracted for HMs in the dust samples at the Riyadh area (affected by industrial activities), whereas two components were extracted for the mining area of Mahad AD’Dahab. In the Riyadh area, Factors 1, 2, 3, and 4 accounted for 57.12...
To explore taxonomic components in the SMAG catalogue, we clustered the 40,039 MAGs into 21,077 SGBs (Supplementary Data 2) based on 95% whole-genome average nucleotide identity (ANI). We annotated the taxonomy with Genome Taxonomy Database (GTDB), which is commonly used13 and considered a ...
