Plant tissue analysis can confirm the adequacy of all nutrients or identify an inadequacy of one or more nutrients. Plant tissue samples should be collected from the correct plant part at the appropriate stage of development. Using Plant Tissue Analysis as a Trouble-shooting Tool

The amount of plant tissue recommended depends on the type of plant and the stage of growth. An amount that fills a paper lunch bag is acceptable. The tables below provide more detailed guidelines. Samples should be collected in a large paper bag or plastic bucket (not metal). Sample Preparation

Plant tissue damaged by insects and mechanical equipment. Plant tissue, which has been stressed by excesses of cold, heat, or moisture. Seeds should not be sampled—they do not reflect nutritional status of the whole plant.

precision laboratory analysis of a plant tissue sample during the growing season. How Can a Tissue Analysis Help? A plant tissue analysis will show the nutrient status of the plants during the growing season and detect unseen, hidden hunger. Plant tissue analysis can also supply information to confirm visual deficiency symptoms.

Sample collection is critical for plant analysis as plant nutrient composition varies with age, the portion of the plant sampled, and many other factors. Mistakes or carelessness in selecting, collecting, handling, preparing, or shipping plant tissue for analysis can result in unreliable data,
