Abstract
Zinc deficiencies were first identified within the United States in citrus orchards being grown on peat soils of Florida (5). The deficiency has since been reported in central Washington on corn and alfalfa grown on newly irrigated land which had been during leveling for irrigation (6, 1). Zinc deficiencies in Kansas are most commonly reported on corn and grain sorghum. These deficiencies within Kansas normally occur only on sites which have had the organic matter-containing A soil horizon removed during the leveling process. Crops growing on these cut sites often show severe zinc deficiency symptoms. The objective of this research was to determine if the probability of zinc deficiencies occurring on a given soil when placed under irrigation and heavy fertilization for maximum yields could be predicted on the basis of a soil test.
