T NJURY to crops grown on solonetz is caused in a ]_ large measure not only by the high pH and alkali concentration, but also by the resulting unfavorable physical condition of the soil and the unbalanced ratio of exchangeable cations. An outstanding feature of solonetz is a low Ca: Mg ratio in the exchange complex, particularly of the B horizon. Data assembled on this point are presented in Table I. Similar data may be inferred from results reported by Ellis and Caldwell (4) for soils in Manitoba. The work reported in this paper is a segment of a more elaborate plan of a study of antagonistic effects of various cations in saline soils. In this segment solonetz or solonetz-like soils of different Ca: Mg: Na ratios were produced and the effects of these on the soil and plant growth studied. Outside the limited data of Antipov-Karataev (i) very little work has been reported on this subject.
