This is a complete list of soil science licensing boards in the United States. State licensing in this context refers to any state regulatory program which limits the professional practice of soil science within state jurisdiction to individuals qualified by the state.
Added to NRHP. March 14, 1985. King Hall (also known as the Horticulture and Agricultural Physics and Soil Science Building and the Soils Building) was built in 1893 and 1896 on the campus of the University of Wisconsin–Madison. In 1985 it was listed on the National Register of Historic Places and on the State Register of Historic Places in 1989.
Francis D. Hole. Francis Doan Hole (25 August 1913 – 15 January 2002), was an American pedologist, educator, and musician, best known for his contributions to mapping the extent of soils and their properties in the Wisconsin region and using inventive lectures and musical performances to communicate and popularize the field of soil science.
The most common engineering classification system for soils in North America is the Unified Soil Classification System (USCS). The USCS has three major classification groups: (1) coarse-grained soils (e.g. sands and gravels); (2) fine-grained soils (e.g. silts and clays); and (3) highly organic soils (referred to as "peat").
A soil test is a laboratory or in-situ analysis to determine the chemical, physical or biological characteristics of a soil. Possibly the most widely conducted soil tests are those performed to estimate the plant-available concentrations of nutrients in order to provide fertilizer recommendations in agriculture.
Symbol used in drawings. Simplified version of a cone penetrometer. The cone penetration or cone penetrometer test (CPT) is a method used to determine the geotechnical engineering properties of soils and delineating soil stratigraphy. It was initially developed in the 1950s at the Dutch Laboratory for Soil Mechanics in Delft to investigate soft ...
The Unified Soil Classification System (USCS) is a soil classification system used in engineering and geology to describe the texture and grain size of a soil. The classification system can be applied to most unconsolidated materials, and is represented by a two-letter symbol. Each letter is described below (with the exception of Pt): If the ...
John Roger Bray was an American-born ecologist known for his collaboration with John Thomas Curtis. [1] The Bray–Curtis dissimilarity is jointly named after them. [2] [3] [4] Bray was born in 1929 to Roger H. Bray, who developed the Bray soil test. [1] [5] A native of Belleville, Illinois, the younger Bray was raised in Urbana, Illinois.
