wo new enhancements in the R7
Tool by Winfield turn yield data
into a scorecard that farmers can
use to easily evaluate input performance
and field profitability. These valuable
insights will help them make informed
decisions season after season.

R7 enhancements
turn data into insights
The Field Response Map spatially
correlates actual yield map data from
the combine with the map originally
used to determine the input prescription for the field. Each map illustrates
areas that responded well or poorly
to that prescription. Examining the
areas of the field that did not respond
as predicted provide an opportunity to
improve productivity potential for the
following year.
The Profitability Map spatially
correlates input costs, either flat or
variable rate, and the yield map data
from the combine to determine the
parts of the field that were most profitable. Less-profitable areas provide the
opportunity to discuss how to better
align input investment with yield potential for the following year. This map
helps farmers, together with their local
agronomists, to manage profitability
potential on every acre.
“Field response and profitability are
two things that have always eluded precision ag,” said Dave Gebhardt, director
of data and technology Winfield.
“‘Did my field prescription work?’
and ‘Did my field prescription increase
my ROI?’ are questions that farmers
will now be able to answer.”
Winfield-affiliated local agronomists
can help farmers analyze the data
derived by these new features and work
with them to implement any revisions
necessary into a plan for next spring.
“Making these types of important
adjustments can help ensure that
farmers are using the right inputs at
the right rates to optimize yield and
profit potential,” Gebhardt said.

Planting date will affect the relative maturity between varieties.
A typical range is shown since environmental conditions will impact seed size.
The disease response listed is a composite of several different observations: the breeders description;
Terral Seed's field observations; county or parish demonstration plots; and variety reaction in
experiment station trials. Disease reactions of varieties can change over time as the disease adapts
to a new host. Check with your county agent for specific information in your area.
NOTE: As a general rule, plant later maturing varieties early and earlier maturing varieties later.
