Breaking News Corn Producers achieve 100% Nitrogen Use
Efficiency!

equal to the amount of N in the removed grain”
Let’s all go home and update our resumes
Agenda
Trimble Acquisition of NTech GreenSeeker Product Developments Field Observations
– Sensor Based N Algorithms– Nitrogen Rich Strips– Sensor Adoption– State of Conventional N Management
Case Study: Dutch Creek Farms
Trimble Acquisition NTech acquired in June of 2009
Goal: Position Trimble as The Leader in Precision Ag– Expands product capabilities – Integrate sensing technology – Leverage Trimble market power to accelerate GS/WS adoption
Consistent with recent acquisitions of:– Rawson Controls– TruCount Clutches– FarmWorks Software
Since 2004, Trimble Ag has evolved from a navigation company to a major force in Precision Ag
Key Trimble Offerings FMX
– 12.1” touch screen controller with 2 integrated GPS receivers
– Planting/Application/Harvesting – Auto Steer / Implement Steering– Field Leveling / Water Mgt– Information Management
EZ Guide 250 and 500– Lightbar– Auto steer– Flat or VR application control – Mapping
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)

RT150 Mapping Only System
Entry Level 3 Sensor Mapping OfferingFully Upgradeable to VR Capabilities
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
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
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 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
Welcome AgLeader & TopCon
If we are going to change the NUE world, it will take many voices.
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…
Blind Excess
Source: Elwyn Taylor ISU Meteorologist
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
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
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: ?
Fall Strip Till: Hog Manure 95 lbs N
Planting into Strips with No Till Planter
v2-v4 Flat Rate Side Dress: 38 lbs
Evaluating Corn at v10-v12
Late Season Sensing v10-v12
Farmer Practice 133 lbs N N Rich Strip 200 lbs N
ISU Calculator corn on corn rate: 181 lbs
*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
Decision: Do Nothing
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
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.
Thank You
