FERTILIZER APPLICATION
Of greatest practical help to modern growers is the ability to reliably
estimate the actual plant food requirements of the crops they wish to grow
each season. Many of these results can be used as a yardstick not only for
insuring proper feeding of the plants but also to achieve these results with
controlled econ
FERTILIZER RECOMMENDATION TABLE
The Fertilizer Recommendation Table is used to interpret the soil test
results. The tests provide a relative measure of the major nutrients present
in the soil in available form, and the table indicates how much fertilizer
should be added to achieve optimum soil conditions.
Read down the nitrogen column to locate the application rate
corresponding to the nitrogen test result. Do the same for phosphorus and
potash. These three figures (in lbs per 2000 sq ft) enable you to determine
what fertilizer mixture to select and how much of it to apply.
Pounds to be Added per 2000 Square Feet

Medium High 5 7 5
Medium 6 8 6
Medium Low 7 9 7
Low 8 10 8
Very Low 10 12 10
NOTE: Evergreens, shrubs, and berry plants should be treated at one-half
the rates given in the table.
