Plant analysis provides two approaches to enhancing fertilizer effectiveness. One is the diagnostic approach where plant analysis is made when there is an obvious growth problem in the field. A sample is taken from the poor growing area and compared to a sample from an adjacent normal growing area.
Ward Laboratories, Inc. suggests using this diagnostic approach for researching production problems. The comparative samples are very important for proper interpretation of the analysis. The testing fee for the normal comparative sample is one- half the regular fee.
The monitoring approach is used to confirm that the plant has proper nutrition. Plant samples should be taken while the crops are at the bloom (reproductive) stage of growth. Samples taken earlier than bloom stage contain higher levels of nutrients. For this reason, it is very important to identify the growth stage for proper interpretation.
