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...
Soil texture refers to the relative proportions of sand, silt, and clay particle sizes, irrespective of chemical or mineralogical composition (see the figure). Sandy soils are called coarse-textured, and clay-rich soils are called fine-textured. Loam is a textural class representing about one-...
The relationship between plants and microbes depends upon various factors like bacterial genetic diversity, climatic condition, and soil composition. Bioaugmentation is a process in which related bacteria and its function are studied. However, biotic and abiotic factors affect the functioning of both asso...
Microbial carbon use efficiency has an important role in soil C cycling. Here the authors test the interactive effects of temperature and moisture and manipulate microbial community composition in soil microcosms, showing a positive relationship between microbial diversity and CUE that is contingent on ...
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...
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 ...
In studies with artificial soils, it was demonstrated that the type of clay mineral present influences the microbial community composition. Therefore, the communities responded differently to the spiking of organic amendments (Ding et al.2013; Babin et al.2013,2014; Pronk et al.2017). This sugge...
’ According to Matschullat et al. (2000), GB ‘is characterized by spatio-temporal changes of the content of heavy metal, which is characteristic for the soil type or region’ and ‘reflects natural composition of heavy metals.’ Another definition of GB is given by Matschullat et al. ...
The pH of biochar can influence the composition and activity of microbial communities in the soil [108]. Alkaline biochar can create an environment that favors certain microbial populations, leading to changes in the decomposition rates of organics and the stabilization of C compounds [108]. This ...
North Africa and Southern Europe. Many ancient civilizations were developed around this region. Countries at the region include: Spain, France, Italy and Egypt. This blog will introduce the geopraphical propoerties of the region, the soil composition and the threats it is facing but mainly focu...
