1.3 Elemental Composition of Earth’s Lithosphere and Soils Most geology, soil science, and environmental science textbooks include a table listing the elemental composition of Earth’s lithosphere or soil. There are several reasons for listing the elemental composition of Earth materials. Soil compositi...
Although some research has been done to the effects of the addition of OMWW on soil characteristics, such as soil hydraulic properties or soil composition, information on the effect of these amendments on other compounds that are retained by the soil, such as pesticides or heavy metals, is scar...
[92], dark soils typically contain more OM than light soils, reflecting the effect of the carbon content on the composition of the sample together with the change in spectral behaviour. This effect can be seen in Figure 7, where the sample with the highest SOC content (36.36 g kg−1) ...
3.2. Variations in the Chemical Composition of Grain of Organically Produced Spelt, Maize, and Soybean When grain yield and its chemical composition were considered, year expressed the highest impact on GY, protein content, and concentration of P, Cu, and Mn in spelt grain, the concentration of...
Notably, soil fauna might substantially affect both of these SOM formation pathways by (1) altering the quantity, quality, and location of organic matter in the soil via bioturbation and transformation processes, (2) altering microbial biomass and community composition via active and/or indirect ...
While soil microbial communities continue to be studied, we can refine our mechanistic understanding of the belowground communities using diverse techniques that become increasingly accessible to describe additional aspects (e.g., diversity, community composition) and functionality, contributing to improving ...

while the development of quantitative science offered new opportunities for improved soil management. The study of soil as a separate scientificdisciplinebegan about the same time with systematic investigations of substances thatenhanceplantgrowth. This initial inquiry has expanded to an understanding of s...
For general descriptive purposes, soil horizons are commonly given abbreviateddesignationsbased on their location in the soil profile and on theircomposition. From the surface downward, they are named O if they form at the land surface and are almost entirelyconstitutedof litter andhumus, A if the...
Plant communities differ in terms of the quantity and quality ofplant exudates(i.e. C sources) and signal molecules, which in turn influence both diazotroph community composition and NS- N2fixation rates (Fig. 4). For example, perennial grasses with their extensive root systems and large amount...
