Plant tissue analysis is a tool to diagnose growth problems in crops. Comparing analytical results from “good” and “bad” areas of a field, makes it easier to determine growth problems related to soil fertility. Petiole analysis is used to monitor fertility levels in crops such as potatoes and cotton. Please contact the laboratory today to discuss how to use plant tissue and petiole testing in your operation.
