Hudak- Wise, Ph. D., Director Plant/ Waste/ Solution Section Brenda R. Cleveland, Section Chief Physical Location: 4300 Reedy Creek Road Raleigh, NC 27607- 6465 Mailing Address: 1040 Mail Service Center Raleigh, NC 27699- 1040 Phone: ( 919) 733- 2655 or visit our Web site www. ncagr. gov/ agronomi Prepared by Brenda Cleveland, Michelle McGinnis and Catherine Stokes revised September 2008 The Plant Analysis Report The plant analysis report has three sections: laboratory results, interpretation and recommendations. Results include concentrations of 11+ essential plant nutrients and sodium, on a dry- weight basis. Ratios of important elements, including N: K, N: S and Fe: Mn, are also provided. The nitrate nitrogen concentration of petioles is reported for cotton, strawberry and vinifera grape. Interpretation is based on suffi ciency ranges established for each crop. Nutrient concentrations are converted to a standard index scale of 0– 124. The scale is divided into zones that indicate whether nutrient levels are deficient, low, suffi cient, high or in excess. An index value of 50– 75 is desirable, in most cases. When appropriate, the report contains fertilizer recommendations and supporting information. Diagnostic reports may also provide site-specifi c suggestions for corrective action. The inclusion of these suggestions will depend on how completely the grower fi lled out the sample information form. Record Keeping Plant analysis reports provide valuable data for making fertilizer management decisions as well as an excellent record of crop nutrient use and needs from year to year under different environmental conditions. Combined with yield data, they can also document nutrient use on fi elds where animal or municipal waste is land-applied. In this way, plant analysis reports can serve as valuable evidence of responsible crop management and environmental stewardship.
