Precision
Definition of precision Webster’s
defines precision
as “the quality or state of
being precise”
 They
also state that “the
degree of refinement with
which an operation is
performed or a
measurement stated “
Planting
Definition of plantingWebster’s
defines
planting as “to put or set
in the ground for
growth”
Precision Planting
Combining the two, I
derive this definition of
precision planting
The
quality or state of
precisely placing a seed
in a medium such as the
soil for growth.

There are many modification that can be made to
planters to make them more precise when it comes
to seed placement
Row openers, press wheels, seed tubes, seed boxes,
seed metering wheels, seed plates, keetons, and
some type of furrow closing device all make up a
single row unit.

Row Openers
Row openers clear trash, cover crops, residue, out
of the way of the seed placement device.
They also break up the soil slightly to open a
trench for the seed to be placed in.
The device shown below allows for more down
pressure to be put on the openers to allow for
better opening of a furrow in no-till systems.
This device allows the openers to float along the
soil surface

Seed Tubes and keetons
Seed Tubes
keetons
Seed tubes deliver the seed from the box to the furrow
Keetons press the seed against the bottom of the furrow so the seed gets
good soil contact. They also can deliver starter fertilizer at low doses.

Row Swath Control
Can be used to stop double planting on end rows
Controls individual row units
16 row planter on 1100 acres->Total Seed Savings: 25 bags at
$200/bag $5000->Yield increase for swath control: 7000 bushels or
$21000 in $3 corn market->One year payback was $26000 or $23 per
acre (Precision Planting).
Row Swatch Control
Can also be used in a variable
seeding situation
Were soil types change,
different levels of plant
populations can be
implemented
Variable Seeding Using GIS
This shows variable rates
being selected using GIS Soil
Data and recommendations
being applied.
A Purdue University / Farm Journal study analyzed Variable Rate versus
a single population setting. The payback is illustrated as:
•Total Acres in Study: 1,300
•Yield Increase for Variable Rate: 15 bu /acre
Total Payback in $3 corn market: $45 / acre or $58,500 on 1,300
acres
