Chemical and Physical Properties of Soils in a Wet Saline Area in Eastern North Dakota
1964
Sandoval, Fred M. | Benz, L. C. | Mickelson, R. H.
A large, imperfectly drained saline soil area in the Red River Valley of North Dakota (glacial Lake Agassiz) was characterized chemically and physically. Two main problem areas were differentiated: one where soils were derived from deep lacustrine sediments of low bulk density with high Mg content frequently, and another, where dense glacial till was close to the surface and was found similar in composition to deep artesian waters having higher contents of Na and B. Dolomite was high in the lakelaid soils with montmorillonite the principal clay mineral. Composition of shallow ground waters was similar to ambient soils. The principal problem is excessive concentrations of soluble salts influenced by shallow water tables. Several chemical and physical interrelationships are explained.
