A COMPENDIUM OF TISSUE NUTRIENT CONCENTRATIONS FOR FIELD-GROWN POTATOES

Current literature was reviewed to evaluate relationships between potato tissue nutrient concentrations and yield. Primary sources (those based on original research) were emphasized to prevent duplicate information. Data were rejected if stage of growth and plant part were not specifically defined. Data that met these criteria were separated by plant part, stage of growth, and nutrient form (soluble versus total nutrient). The information was then compiled to illustrate the range of reported values for each nutrient, stage of growth, and plant part. Values are presented for deficient, low, sufficient, high, and toxic levels of nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, boron, chlorine, copper, iron, manganese, and zinc.
