new greenseeker developments
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

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

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
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
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
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
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
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
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.

lessons
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
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.
