Solonetz (, p=səlɐˈnʲɛts) is a Reference Soil Group of the World Reference Base for Soil Resources (WRB). They have, within the upper 100 cm of the soil profile, a so-called "natric horizon" ("natrium" is the Latin term for
sodium). A subsurface horizon (
subsoil), higher in
clay content than the upper horizon, has more than 15% exchangeable sodium. The name is based on the
Russian language соль (sol, meaning
salt). The Ukrainian folk word "solontsi" means salty soil. In
Ukraine, many villages are called
Solontsі.
Solonetz zones are associated with Gleysols, Solonchaks and Kastanozems.
In USDA soil taxonomy, Solonetz corresponds to sodium-rich Alfisols.
