Agric.) 17 These are soils which have become saline with sodium salts (saline soils) and alkaline soils (‘solonez’ soil) formed from these as a result of removal of the salt. 1925,1927[see solonchak]. 1932E. J. Russell Soil Conditions & Plant Growth (ed. 6) iv. 268 The last stage, when the solonietz has been exposed to prolonged leaching, is the solod of the Russians. 1938[see planosol]. 1968H. C. T. Stace et al. Handbk. Austral. Soils vi. 153 The essential features of solonetz are prominent texture differentiation with an abrupt boundary between loamy A horizons and clay B horizons, neutral to alkaline surface soil and strongly alkaline subsoil [etc.]. 1972J.
