provide clues to nutrient problems
in the field if we pay attention to
the symptoms they show. Unfor
tunately, by the time visual symp
toms are observed, the potential
yield of the crop has probably
been severely reduced. This “hid
den hunger” is one of the biggest
yield robbers.
Know the growth stages and ex
pected development rate of a
healthy crop. This will be helpful
in identifying deviations from nor
mal growth often the first sign
of nutrient deficiences. If growth
is unusually slow or if plants ap
pear stunted, take leaf samples for
laboratory analysis. Know the
common nutrient deficiency
symptoms for the crops you are
growing. For many crops, nitro
gen deficiency causes yellowing
of the leaf tissue (along the midrib
of grassy plants), usually visible
on lower leaves first. Supplement
al nitrogen application may help
recover some lost yield potential if
the crop is not yet fully developed.
Potassium deficiency causes
leaf margins to turn yellow and
eventually die. Lower leaves ex
hibit symptoms first, because part
of the potassium is moved from

them to the more actively growing
parts-of the plant when insuffi
cient amounts of potassium are
available for normal growth. Re
sponse to supplemental potassium
applied after symptoms develop is
not very likely, but increasing po
tassium on that area next year may
help prevent recurrence of the
problem.
Phosphorus deficiency shows
up as a purple coloration of newly
developed leaves. Since phos
phorus is critical to sugar utiliza
tion in plants, its deficiency leads
to a buildup of sugar in the leaves
and reduced chlorophyll content,
allowing the purple pigments to be
more visible. Phosphorus defi
ciency may be induced by re
stricted root growth or cool tem
peratures. Nutrient applications
can be adjusted to prevent recur
rence of the deficiency in succes
sive years. The symptoms may
disappear as the root system ex
pands and growing conditions im
prove.
Nutrient deficiency symptoms
are often actually caused by other
problems such as insect feeding,
compaction, poor root develop
ment. disease injury, competition
from weeds, poor drainage or me-

chanical injury to the plant. These
problems inhibit the uptake or
utilization of available nutrients.
The real cause may be masked by
other symptoms, so don’t be too
quick to diagnose the cause-effect
relationships. On the other hand,
maintaining adequate nutrient
availability will often reduce the
impact of these other yield limit
ing factors.
Make use of old tools as well as
new technology to help detect,
identify and correct nutrient prob
lems. Soil testing is one source of
clues. With the availability of
more intensive sampling data,
areas of low nutrient levels may be
easier to locate. Make a special ef
fort to check such areas. Plant
analysis is another useful tool for
identifying nutrient deficiencies.
Take samples from suspected de
ficient plants and also from
healthy plants for comparison.
Standard sufficiency threshold
values are available for most
crops, but (he comparison ap
proach may be more useful in field
diagnostics. Quick-test kits can be
used as a first cut analytical tool.
Such tissue tests should be con
firmed with laboratory analysis
before making major nutrient

the specific geographic location of
deficiency symptoms and where
soil and plant samples are taken
for analysis. The GPS coordinates
can link these observations to
othet data bases such as soil sur
vey, soil test data and yield maps.
These tools are all helpful in deter
mining the true cause-effect rela
tionships resulting in the nutrient
deficiency. If GPS is not avail
able, take detailed notes on where
symptoms occur in the field. This
will be valuable for future man
agement decisions.
