Some Beneficial
Uses...
-
Apply more or less
commercial fertilizer to parts of a field according to fertility.
If we think back to when farmers began to use fertilizer, many times
it has been a "blanket" application of fertilizer across the entire
field for years upon years. Since soil types directly affect the
yield of our crops, yields will always vary across the field. Since
higher yielding crops consume more nutrients than lower yielding
crops, in most cases, our years of blanket spreading has not put
enough nutrients back into some of the high yielding soils. It is
very common to see the highest yielding areas of a field test the
lowest in fertility, and hilltops and lower producing areas higher
in fertility. This goes back to the fact that we have been "blanket"
spreading, and not applying enough fertilizers to our higher
yielding soils. Lower yielding soils do not consume as many nutrients, which is why we see
hilltops high in fertility, especially phosphorus, because it has
been applied at a rate higher than the crops have been removing. Click
HERE for a real
example of this. Many times, you will use the same amount of
fertilizer as you would spreading a maintenance, you are simply
putting more where you need it and less where you don't.
-
Apply Starter
Fertilizer only on soils that will benefit. It is proven that
starter fertilizer will rarely be beneficial on some soil types, and
the majority of the time, be beneficial on lower, heavier soils,
especially soils with a high pH. There is no reason to waste the
time and money to apply starter to soils that will see no benefits.
-
Apply soil applied
herbicides according to soil types. Soil texture and organic
matter directly affect the reactions of soil applied herbicides in
the soil. For this reason, you may be over-applying on some soil
types, which is not only wasting money, but may harm the following
crop. Under-applying on other soils with higher organic matter may
not get effective weed control.
-
Lime Applications.
Since pH varies greatly across a field, it is very beneficial to
have a field soil tested prior to lime applications. Applying a
"blanket" rate of lime across an entire field can be expensive, and
you may even be hurting yourself in some parts of the field that
does not require lime.
-
Applying products to
select areas. Ammonium Sulfate, for example, can benefit you in
a high pH by releasing some of the phosphates that are "tied up" due
to high pH.
-
Variable Apply
Nitrogen based on organic matter, soil types, management zones,
or to balance out nitrogen credits from dry fertilizer applications
-
Variable Rate
Seeding population to match soil types
-
Many other uses...
