A plant analysis has three main applications:
- to confirm a suspected nutrient deficiency or toxicity when visual symptoms are present
- to monitor plant nutrient status in an effort to achieve optimum yield while protecting the environment
- to serve as a basis along with a soil test for fine tuning fertilization programs
When visual symptoms of a suspected nutrient deficiency are present, take a soil sample at the same time and in the area that the plant tissue is collected.
