Abstract
Zinc deficiency in Utah is found in about 7 per cent of the orchards. The severity varies from minor cases to sever instances in which many of the trees have died. The areas where zinc deficiency is found are becoming more extensive as land cultivation continues.
The treatment of the disorder is expensive and must be repeated often, for it cannot be overcome by the addition of zinc to the soils. The soils in Utah seem to have ample zinc, but in areas where zinc deficiency occurs it apparently is in a form which is not available for plant growth.
Preliminary evidence indicates high soluble phosphate in the soil may reduce the availability of zinc to higher plants. It is the purpose of this study to test the validity of this hypothesis. This report is not an attempt to determine the mechanism of zinc fixation or its reduction in availability; its purpose is to determine if there is a reduction in zinc availability as measured by uptake by plants in the presence of high soluble phosphate.
