Classification, Properties, and Management of Aridisols

Families

Aridisols Slide 50

The next level of soil taxonomy is the Family. At the Family level, soils are grouped together that have a similar crop response to management.

Aridisols Slide 51

Usually three modifiers are added to the Subgroup name to make the Family name. These modifiers refer to physical and chemical properties important to management and use of the soil. The first refers to the particle-size class of the soil, the second to the dominant mineralogy, and the third to the soil temperature regime. Before experiments and knowledge accumulated on soils in one area can be used to guide soil management practices in other regions, classification should be extended further to phases of Families, to other similar site characteristics, or to the Series level of classification (refer to Nominal Systems in Soil Classification Systems).
