Please submit plant samples
in paper bags.
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 to researching production problems. The
comparative samples are very important for proper
interpretation of the analysis. The cost for comparative
testing is first sample at regular fee, second sample at
one-half the regular fee.
The monitoring approach is used to confirm that the
plant had proper nutrition. Plant samples should be taken
when the crops are in the bloom (reproductive) stage of
growth. Samples taken earlier than bloom stage contain
higher levels of nutrients while samples taken during grain
fill will be lower. For this reason it is very important to
identify the growth stage for proper interpretation.
