Instructions for Taking Samples for Plant Analysis Read these instructions carefully Taking a Sample Use the instructions in this publication to obtain s which accurately reflect nutritional status of the crop submitted for analysis. Results of the analysis will determine whether problems in responses are due to a nutritional problem. Plant analysis can also be used to monitor and maintain appropriate patterns. Completing the Plant Analysis Request Form For every leaf, petiole or fruit sent to the Laboratory for analysis there must be an accompanied request form. The request form is designed to provide a direct communication between the laboratory and the crop specialist who will interpret the results. Be sure to complete this form.
