Agronomic Services — Plant Tissue Analysis

Kristin A. Hicks, Ph.D., section chief
Plant tissue analysis can indicate whether plants contain the concentrations of essential nutrients necessary for optimum growth. Results help growers monitor nutrient uptake, correct deficiencies before they reach a critical stage and, for some crops, time harvest appropriately.

Note: Plant tissue analysis does not include analysis of forage plants for use as animal feed. Feed analysis is provided through the NCDA&CS Food & Drug Protection Division.
