Organic Corn Fertilizer
 When compared to other crops, corn has higher
fertility requirements. It's growth and development
needs soil nutrients, which is why
organic corn fertilizers rich in nitrogen (N), phosphorus (P),
zinc (Zn), iron (Fe) and potassium (K) are recommended.
Choosing the Right Organic Corn
Fertilizer
With hundreds of organic corn fertilizers available,
choosing the right one can be a dificult task,
so here are a few tips that will help you choose the
best organic corn fertilizer for your needs.
First, your organic corn fertilizer needs should be
based on a realistic expectation of yields. You can
choose organic corn fertilizers keeping in
mind the amount of residual nutrients in your soil
as well as ammonium nitrate in irrigation water. It best to do
this with regular soil and irrigation water
testing.
If corn lacks one or more element in their soil, they will show deficiency
symptoms such as yellowed leaves or purpling of the
corn ears, with each symptom corresponding to a
certain elements that are missing. Therefore,
the best way to deal with these
elemental deficiencies is to apply the right organic corn
fertilizer.
A nitron
deficiency usually causes the lower leaves of corn to
be stunted, producing a sickly yellow color. Therefore,
apply organic corn fertilizer with urea, anhydrous
ammonia, nitrate, calcium, potassium, sodium, ammonium, and
urea ammonium nitrate solution.
A deficiency
in phosphorus could result in
the leaves turning purple or dark green, with delayed
maturity and poor development of the ear. The cure for this is
to use the organic corn fertilizer with granular
monoammonium phosphate, diammonium phosphate and liquid
ammonium phosphate.
A potassium
deficiency will result in burning at the lower leaf tip and marginal, weak stalks,
small ears and slow growth. Organic corn fertilizers rich in potassium
chloride, potassium sulfate, nitrate, hydroxide, or magnesium
sulfate will help solve the problem.
A
shortage in the mineral zinc will commonly
result in decreased stem length and mottling. The
best organic corn fertilizers to deal with this will
contain zinc sulfate, zinc oxide, zinc chelates, zinc
chloride.
To prevent corn from developing
interveinal chlorosis in its early
leaves, it's best to use organic corn fertilizers rich in
ferrous sulfate, ferric sulfate, ferrous ammonium sulfate and
iron chelates.
There are lots of
different minerals corn may lack and,
fortunately, many organic corn fertilizers that
will prevent these
shortages.
However, even better results
can be achieved if organic corn fertilizers are used
in along with weed and insect control. Some
manufacturers are now starting to produce organic corn
fertilizers with “pesticidal” functions. As
yet, this isn't a common additive in organic corn
fertilizers, but it will prove to be a convenient,
two-way method to a healthier crop yield.
