Plant tissue analysis is a valuable aid in crop management. Alone, it can be used for making fertilizer recommendations for certain crops, such as tree fruits and grapes. For other crops, plant tissue analysis in combination with soil test information is the recommended approach for diagnosing nutrient deficiencies and determining fertilizer requirements.

Samples submitted for tissue analysis will be analyzed for 10 elements: nitrogen, phosphorus, potassium, calcium, magnesium, manganese, iron, copper, boron, and zinc. The final report includes the analytical results along with an interpretation based on the crop specified. Standard plant analysis kits may be purchased from the county offices of Penn State Extension.
