Nutrient Content of Plants:
A plant analysis interpretation is based on a comparison of the nutrient concentration found in a particular plant part taken at a specific time with known desired value or ranges in concentration. One method of interpretation is based on "critical values," a critical value being the concentration below which deficiency is likely to occur.
