Re:NOW HOLD THE PHONE/FOLIAR FEEDING!


Mike,

I can't help you with the warm water trick, but I would like to jump in on
foliar feeding! You mentioned that it seemed to make no difference for you,
that it was once thought of as a must, now they say it does not do much! I
don't agree with this in part for various reasons. Most Foliar Feeds will
only work well in conjunction with soaker hose irrigation. If you are
overhead sprinkling, it really won't accomplish a tremendous amount as much
of the nutrients are washed off before they are absorbed, as you suggest.
Sure, the roots will absorb some nutrients that are washed off into the
ground, but the foliar feeding will not benefit the plant to the extent of
absorption through the leaf! Here is some further information as to why,
these statistics are taken from an independent agricultural testing
laboratory!

Rates of Nutrient Absorption into plant tissue

Nutrient                         Time for 50% absorption

Nitrogen (as urea)           1/2 - 2 hrs.
Phosphorus                    5 - 10 days
Potassium                     10 - 24 hrs.
Calcium                         1 - 2 days
Magnesium                    2 - 5 hrs.
Sulfur                             8 - days
Zinc                               1 - 2 days
Manganese                    1 - 2 days
Iron                                10 - 20 days
Molybdenum                  10 - 20 days

As you can see from the delayed rates of absorption, foliar feeding would
provide little help if the plants are overhead watered due to the time
delay of absorption into the plant tissue.
However, if soaker irrigation is used no nutrients would be washed from the
leaves providing the plant and fruit substantial benefit. Make sense?
