What is soil science?
Soil Science has traditionally been an umbrella for soil physics, soil chemistry, soil microbiology, soil fertility, soil morphology, and soil technology. The area dealing with soils as entities in and of themselves has commonly been referred to as pedology (Arnold, 1983 ). Pedological activities in the United States have been prominent in the soil survey. The soil survey is the institutional construct that implements the concepts of the discipline of Pedology. After the land-grant colleges were authorized and charged with teaching agricultural knowledge, home economics, mechanic arts, and similar job training skills, the US Weather in 1894 created a Division of Agricultural Soils ( Helms et al., 2002 ). A bit later agricultural experiment stations at those universities were federally funded and soon began the long-standing partnership of federal and state agencies and organizations. Since 1899 the partnership in soil surveys has been called the National Cooperative Soil Survey (NCSS). When the Soil Conservation Service was formed in 1935 their soil surveys were primarily for privately owned farms rather than the county soil surveys of the National Soil Survey group. All of the soil information was provided without charge and that is true today.
Why are soils important to ecosystems?
Soils provide and support many interpretive functions in ecosystems. All soil functions are environmental because soils are integral parts of terrestrial ecosystems. Important ones include biomass transformations, partitioning of water, regulation of fluxes, providing habitats, and other uses.
What is hydropedology in soil science?
Hydropedology is an integrative field of soil science, which incorporates the concepts of pedology, soil physics, and hydrology to understand soil–water interactions at various scales (Lin, 2003; Lin et al., 2005, 2006 ). Another integrative field that is rooted in pedology is pedometrics, which by contrast incorporates soil science, geographic information science, and statistics ( Grunwald, 2006 ). Defined as “ the application of mathematical and statistical methods for the study of the distribution and genesis of soils ” ( Heuvelink, 2003 ), pedometrics is concerned with quantifying soil variation in terms of its deterministic, stochastic, and semantic components. A subset of pedometrics is digital soil mapping (DSM), also referred to as predictive soil modeling ( Scull et al., 2003) and quantitative soil survey ( McKenzie and Ryan, 1999 ). Lagacherie (2008) has defined DSM as “ the creation and population of spatial soil information systems by numerical models inferring the spatial and temporal variations of soil types and soil properties from soil observations and knowledge and from related environmental variables. ” The explicit geographic nature of DSM aligns it with hydropedology because hydropedology has been advocated as a means to study the relationships between soils, landscapes, and hydrology ( Lin et al., 2006 ). Therefore, DSM can provide effective linkages for the integration of pedology and hydrology. Lin (2011) referred to the development of such linkages between hydropedology and digital soil mapping as “ an exciting research area, which can improve the connection between spatial soil mapping and process-based modeling. ”
Why is relative soil water content similar to matric potential?
Relative soil water content is similar to matric potential because it normalizes water content against field capacity – the capacity for soil to hold water after gravitational drainage ( Reichstein et al., 2003 ).
What is pedology in science?
Pedology is a subdiscipline of Soil Science; it is an interpretive venture into the existence of surficial earthy materials that we call as soils. It is a probabilistic world; all measurements contain uncertainty. Measurements do not include value judgments. Numbers to not care and soils do not care, people do.
What is the National Cooperative Soil Survey?
