Dichloromethane (DCM, methylene chloride, or methylene bichloride) is an organochlorine compound with the formula C H 2 Cl 2. This colorless, volatile liquid with a chloroform -like, sweet odor is widely used as a solvent .
Digital soil mapping (DSM) in soil science, also referred to as predictive soil mapping [1] or pedometric mapping, is the computer-assisted production of digital maps of soil types and soil properties. Soil mapping, in general, involves the creation and population of spatial soil information by the use of field and laboratory observational ...
For each soil monolith, there is supplemental information about the site of sampling (e.g. landscape, land use, parent material and climate), a detailed profile description for each soil horizon or layer, and data on chemical compositions and physical features. The museum displays examples of the main (32) WRB Soil Reference Groups of the World ...
They may have either a negative charge provided by the attached hydroxyl ion (OH −), which can attract a cation, or lose the hydrogen of the hydroxyl to solution and display a positive charge which can attract anions. As a result, they may display either high CEC in an acid soil solution, or high anion exchange capacity in a basic soil solution.
ISRIC - World Soil Information, also known as the International Soil Reference and Information Centre, is a science-based independent foundation.It was established in 1966, following a recommendation by the International Society of Soil Science (ISSS, now known as the International Union of Soil Sciences (IUSS)) and the United Nations Educational, Scientific and Cultural Organization (UNESCO).

The most important is dichloromethane, which is mainly used as a solvent. Chloromethane is a precursor to chlorosilanes and silicones . Historically significant (as an anaesthetic), but smaller in scale is chloroform, mainly a precursor to chlorodifluoromethane (CHClF 2 ) and tetrafluoroethene which is used in the manufacture of Teflon.
Environmental soil science addresses both the fundamental and applied aspects of the field including: buffers and surface water quality, vadose zone functions, septic drain field site assessment and function, land treatment of wastewater, stormwater, erosion control, soil contamination with metals and pesticides, remediation of contaminated ...
