FERTILIZER APPLICATIONS
Test results should not be the only consideration when establishing a
fertilizer program. Soil composition, drainage, climate, previous fertilizer
programs, and the type of plant must also be considered when
determining the type and amount of fertilizer needed. The following
table offers quick-reference general guidelines to correlate soil test results
and fertilizer application rates. These guidelines can be supplemented by
the information in the LaMotte Soil Handbook (Code 1504). Consult
your local agricultural extension services for advice on establishing a
fertilizer program specific to your area.
