New greenseeker developments l.jpg
New GreenSeeker Developments

  • RT Commander Pro

    • 2007: Envisioned the need to consider historic information with real time rate decisions

    • RTC Pro is the first software to simultaneously access historic and real time information

    • Override, Enhance or Restrict real time algorithm- based rates based on zone delineation.

    • Applicable for:

      • VR planting populations

      • Center pivot field corners

      • Extreme soil or topographical variance

      • Any desired zone delineation (yield, Veris, etc)


Greenseeker rt commander pro l.jpg

GreenSeeker® RT Commander Pro

When setting up a job, RT Commander Pro includes a background prescription map option.

Completely override the algorithm in selected areas, or

Multiply the algorithm values to increase or decrease the recommended rate


Slide8 l.jpg

GreenSeeker® Background Map

The pre determined management zones appear on the monitor as a background map.

The target rate applies outside the bounded areas, but is replaced by the over-ride prescription value (80) in the example above.

Where do we go from here l.jpg
Where do we go from here?

  • Broader Controller Compatibility

    • GreenSeeker is Inclusive Technology-not exclusive. This is a barrier to adoption.

  • Sensor integration through ISO BUS development & standardization

    • Simplifies controller and user interface

  • Boom Section Control

    • “Accuracy is Addictive”


Feedback from the field l.jpg
Feedback from the Field

  • University/Researcher Algorithms:

    • Add credibility, but Farmer’s are skeptical

    • Viewed as a guide or compared to their N program

    • See GreenSeeker as a tool to improve “their own” nitrogen strategy via custom Rx option

    • Prefer local or regional algorithms

      • Universal Algorithm must allow for customization

    • Algorithms are often “tweaked” to achieve acceptable rates


Nitrogen rich strips l.jpg
Nitrogen Rich Strips

  • Stop apologizing for Nitrogen Rich Strips!

  • They should be considered a BMP with or without sensor technology

  • Virtual Reference Strips do nothing to advance NUE

    • Just because you identify a peak value does not mean it is sufficient in N, or is representative of maximum seasonal yield potential

    • Still requires many passes to find “peak” value

    • Best fit for VRS is nitrogen rescue situations


Adoption rates l.jpg
Adoption Rates

  • We’re changing Nitrogen practices; not making farmers better at what they are already doing

    • Side dress is too often a minority practice

    • Late stage crop N assessment is bothersome

  • Sensing requires a cultural change:

    • “Grandpa didn’t do it like this”

  • Best adoption model: No Till/Strip Till

  • Expect slow steady growth, unless:

    • New regulations drive adoption

    • Economics shift to incent adoption

    • Competition enters the market

  • If we are going to change the NUE world, it will take many voices.


Revisiting the n problem l.jpg
Revisiting the N Problem

  • Overriding N Fertilizer Mentality

    • Every year has homerun yield potential.

    • Weather conditions have little influence on the nitrogen rate decision.

    • Crop Advisors don’t take the time to account for mineralization in the total N supply

    • One pass N is easy and usually works well

    • “More (N) Is Better”

  • So what do we get…

What can change this mentality l.jpg
What can change this mentality?

  • Economics:

    • The high N prices of 2008 forced producers to collectively think about their N rates for the first time in years.

    • Farmers are trained to wait for economic incentives like EQIP before they act—this can actually delay adoption while they wait for a program & funding.

    • Since researchers acknowledge that mineralization exists, more of them could start considering it in their N rate recommendation, or we could….

    • Demonstrate that even in with today’s economics, there are large returns to capture.


Case study in progress dutch creek farms l.jpg
Case Study (In Progress): Dutch Creek Farms

  • Early GreenSeeker Adopter-2005

  • Views change as opportunity for short term competitive advantage

  • Recognized for outstanding environmental stewardship relating to farming practices


Corn production program l.jpg
Corn Production Program

  • North Central Iowa

  • 3rd year corn on corn

  • Strip Till

  • 3 Pass Nitrogen Plan

    • Fall Strip Till NPK (manure): 95 lbs

    • Early side dress v2-v4: 38 lbs

    • V10+ GreenSeeker side dress: ?

Decision: Do Nothing

Farmer Practice 133 lbs N

N Rich Strip 200 lbs N

*95 lbs Fall Strip Till Manure

*38 lbs v3 UAN side dress

*95 lbs Fall Strip Manure

*105 lbs v3 UAN side dress

NDVI = .801

NDVI = .795


Lessons l.jpg
Lessons

  • Grower practiced BMP’s with respect to N Timing, Placement and Product

  • Without the right tools (NRS & sensors), grower may have unnecessarily applied an additional 46+ lbs of N

  • Sometimes you get paid to do nothing

  • Anticipated Savings:

    • 46 lbs x $.35 x 3900 acres = $62,790

    • $4 /ac application x 3900 acres = $15,600

    • Total avoided cost: $78,390


Sensor impact on nue l.jpg
Sensor Impact on NUE

  • If he harvests 180 bpa corn:

    • GreenSeeker NUE = .75

    • ISU Calculator NUE = 1.0

    • NDVI estimated yield potential: 209 bpa (.636 NUE)

  • That’s 179,400 lbs of N that didn’t go down the river….and that’s just one operation.
