Soil Composition Research

As mentioned above, Quaternary glacier, glacier alluvial deposits, alluvial sediments do not exist, but they may occur in protected undulating places. The main soil-forming material is the Triassic Trapper rock which exists everywhere. After Sokolov et al. (2002) Soils in this area are mainly derived from rock residue or loose derivatives from deposition and solvation. In general, the mineralogical and chemical composition of "sediment cover" is similar to the underlying rock (Sokolov et al., 2002). Due to the low thermal condition, chemical weathering is hindered, but the physical and low temperature production process dominates the soil formation.

According to soil scientist Ann McCauley of Montana State University, the soil is made up of minerals, soil organic matter (SOM), water, and air. The actual composition of these different components in the soil has a large effect on porosity; that is, it affects the movement of water through the soil and through the soil (McCauley, 2005). And healthy ecosystems are absolutely essential. A combination of soil particles is called "agglomeration" and when water enters the soil it is healthy, it keeps porosity and moisture transfer slow and productive, which means "improving fertility and carbon emissions To do. "

Soil particles can be classified by their chemical composition (minerals) and their size. The soil particle size distribution and texture determines many characteristics of the soil, in particular the permeability coefficient and water potential, but mineralogy of these particles can change these characteristics greatly. The best soil particles, clay mineralogy are particularly important. Gravel, sand and silt are larger soil particles and their mineralogy is often inherited from the soil parent substance, but weathering products (eg calcium carbonate or iron oxide tuberculosis) or the rest of the life of plants and animals .
