DlO—Lancaster Farming, Saturday, June 6,1981
NEWARK, Dela. Cool weather
and heavy rains on Dehnarva have
created less than ideal growing
conditions for many vegetable
crops this spring. Cucurbits and
warm season crops like tomatoes,
peppers and eggplants, in par
ticular, have suffered.
Because of the slowdown in
growth, this would be a good tune
to consider using a foliar nutrient
on these crops, savs University of
Delaware Extension Vegetable
Specialist Mike Orzolek.
“Root development hasn’t been
what it should be, so uptake of
nutrients from the soil is
minimal,” he says.

Give cold-stalled vegetables lift with foliar feeding
more root development and cause
plants to resume normal growth.
“Foliar nutrients work best
when plants have been under
stress, and that’s exactly what
we’re seeing,” he says.
Other stressful conditions that
warrant foliar feeding are dry
weather, hail damage, disease,
and insect feeding in other
words, anything that reduces
growth or puts the plant into shock.
Foliar feeding has several ad
vantages over conventional
feeding throught the soil.
“Probably the biggest ad
vantage,” says Orzolek, “is that
nutrients are placed directly on the
leaves, so that the plant’s needs

are rapidly met. Compared to this,
feeding through the soil involves a
wait for sod/root exchange to
occur, followed by translocation of
nutrients from the roots to the top
of the plant where most of the
growth is taking place.’ ’
Foliar nutrients have another
advantage. Because of their for
mulation they act as buffers,
stabilizing the pH of the solution.
So if you’re going to apply an in
secticide or fungicide at the same
tune, it will remain chemically
viable for a longer tune when
mixed with these nutrients, he
points out.
“Without this buffering effect,
the pH starts to drop when

pesticides are put in solution and
they quickly break down,” he says.
“But if you mix one of these
pesticides with a foliar nutrient
and get a phone call or it starts to
ram, if probably won’t matter if
you can’t get the material on the
field for a few hours, or even until
the next day. It will still be usable.
Otherwise, you’d probably have to
throw the chemical away and mix
up a new batch.”
Because they’re liquids, foliar
nutrients blend in well with most
pesticides. Combined this way, you
don’t have to make a special trip
across the field to fertilize, as you
would if you were applying dry

fertilizer. This saves both time and
energy.
Several companies are now
marketing foliar nutrients. These
products are formulated to provide
low rates of N-P-K plus
micronutrients either in
dividually or in combinations
tailored to meet the needs of the
particular crops. One may provide
boron for cauliflower. Another
may provide additional potassium
and calcium to improve fruit
quality and prevent blossom end
rot on tomatoes.
“Don’t consider foliar feeding a
substitute for your regular
program for side dressed or
broadcast N-P-K in their con
ventional forms,”
says Orzolek. “Use foliar feeds as
supplements.”
Even if there’s been no special
stress and plants are growing
normally, some vegetable crops
with special micronutrient needs
will benefit from supplementary
foliar feeding. Applying boron this
way on cantalopes, for instance, is
a good way to unprove fruit quality
and increase storage life.
Use the same equipment you use
for pesticide applications, when
foliar feeding. These nutrients can
also be flown on by airplane. Their
benefit definitely outweighs their
cost.
Right now, while we’re seeing
cold damage on many vegetable
crops, is a good time to apply foliar
nutrients, Orzolek concludes.
