Plant Tissue Analysis
Purpose
Plant tissue analysis measures the concentrations of essential plant nutrients in plant leaves and petioles. Analytical results are used to evaluate crop nutrient status, detect toxicities, and correct deficiencies.
The Agronomic Division accepts plant tissue samples from both individual growers and research institutions, nation-wide. Select the submission process below that best describes your operation. If you are uncertain about your submission category, please contact the Plant Laboratory Director or Agronomist.
Plant tissue analysis is not applicable to:
- Forage crops for use as animal feed. Forage and feed analysis is provided through the NCDA&CS Food & Drug Protection Division.
