Popis:	Field experiments were conducted during 1977 and 1978 to determine the relationship between percent exchangeable Ca, Mg, and K in the soil, and yield, quality, and leaf concentration of 11 elements for several potato cultivars. The highest yields were obtained in soil containing a combination of 5% Mg and 5% K of the cation exchange capacity. All cultivars grew equally well in the high Ca field as in the low Ca field. Potato scab was no problem. Potassium treatment levels had a consistent effect on yield, specific gravity, and chip color. Specific gravity decreased and chip color improved as the K treatment levels increased from 2 to 8% of the CEC. Leaf elemental concentrations showed few consistent effects as a result of the Mg and K soil treatments.
