With plant tissue testing, you can monitor nutrient status throughout the growing season and detect a nutrient deficiency before signs of stress appear. This type of analysis takes a precise measurement of the plant’s nutritional profile at the time the sample was taken. When used in conjunction with a soil analysis, tissue testing can provide information on what nutrient levels are most limiting to growth and how best to correct them.
