MICRONUTRIENTS YOU CAN’T IGNORE
You may want to use an N-P-K fertilizer
that has had boron added to it already
to ensure you’re applying it in a uniform
fashion. You can use a spray instead, but
this is often going to cost you more in the
long run. Testing your soil after applying is highly advisable since there is the
possibility of boron building up to toxic
levels for your next crop.
COPPER
Copper is involved with several enzymes
and works to catalyze reactions that
occur during plant growth. It is related
to vitamin A production in plants while
helping the synthesis of proteins. Copper
should be applied to the soil, but keep in
mind that adding copper to the ground
can create a residual effect that could
last up to eight years. So, as with boron,
it is important to test your soil to ensure
your plants are not exposed to toxic
levels of copper.
ZINC
If you’re finding that your yields
are limited and should be higher, a
deficiency in zinc is probably the culprit.
Plants only require a small amount
of this micronutrient, but if they are
deficient in it, they’re unable to produce
the high yields you may be used to
seeing. Zinc can be added to your soil or
applied as a spray to the leaves. It might
need to be applied a few times before
reaching the right amount in the soil.
Residual effects are possible with zinc as
with copper and boron, so it’s best to test
your soil before and after applying it.

Some states have even changed the
recommended application rate for zinc
due to the possibility of residuals.
MANGANESE
Manganese is responsible for a portion
of the enzymes that allow a plant’s
metabolism to function. It is also vital
for photosynthesis. This micronutrient
will help speed up germination and
Adding copper to the
ground can create
a residual effect
that could last up to
eight years.
