Plant Tissue Analysis

Plant Tissue Analysis

Plant tissue analysis offers a precise measurement of the nutritional status of a plant at the time the sample was taken. It is a ‘snap shot' in time. Results from a tissue analysis allow a grower to detect a nutrient deficiency before the plant exhibits physical symptoms. When tissue testing is used in conjunction with a soil analysis, it can provide information on what nutrient levels are most critical and how best to correct them.

Plant tissue analysis can be performed on leaf samples and/or petiole samples, and should be a routine part of every crop producer's nutrient management program. 

Remember, a good plant analysis relies on proper sample collection. Refer to the "Sampling Instructions" pages for plant sampling guidelines.
