International Society of Soil Science

International Society of Soil Science, has a system that includes 26 soil groupings. There are many other systems including those developed by Canada, France, the former Soviet Union, China, Australia, and other countries. Each recognizes a different number of major soil groups or soil orders.

These problems were addressed in a paper published by MacCarthy (1976) wherein it was proposed that an international reference collection of humic substances be established. The potential benefits that would result from such a collection were outlined in the paper. That proposal was further promoted by MacCarthy and Malcolm (MacCarthy and Malcolm, 1979 Malcolm and MacCarthy, 1979), and at the Congress of the International Society of Soil Science in 1978 (MacCarthy and Malcolm, 1978) a special working group was formed to examine the possibility of establishing an international standard collection of humic substances. In 1981, an international group of scientists met in Denver, Colorado and formulated a plan for generating a suite of standard humic substances which would be available to researchers worldwide. It was decided to extract and purify humic and fulvic acids from the soil, peat, leonardite, and aquatic sources by a carefully...

This is the International Soil Science Society designation. The United States Department of Agriculture (USDA) defines sand as ranging from 2 to 0.05 mm in diameter. 

According to the U.S. Department of Agriculture (USDA) method, the sand particles will settle to the bottom of the cylinder in 2 min, leaving silt and clay in suspension. The International Soil Science Society (ISSS) uses the 12-min time period for sand to settle. After 24 h, all of the silt particles have settled, leaving only clay in suspension. The hydrometer reading at each of these intervals is converted to grams of soils per liter using a correlation chart. See Workplace Scene 15.4.
