PRECISION FARMING: ADOPTION, PROFITABILITY, AND MAKING BETTER USE OF DATA T.W. Griffin, J. Lowenberg-DeBoer, D.M. Lambert, and J. Peone Site Specific Management Center - Purdue University T. Payne and S.G. Daberkow USDA-ERS

3 part presentation 1) Adoption trends in the US and Worldwide 2) Review of PA profitability literature 3) Making better use of yield monitor data

Adoption Trends Worldwide network of collaborators USDA ARMS study PA Services Dealership Survey –Whipker and Akridge, 2004

VRT Offered by Ag Retailers 67% of service providers offer VRT 40% offer single-nutrient VRT –Still less than 50% by % offer multi-nutrient VRT in 2004 –28% of providers expect to offer by 2006 <10% offer VRT - seeding Source: Whipker and Akridge, 2004

GPS Lightbars Purdue Davis Farm

GPS Lightbar Guidance used by Service Providers 61% offer applications with GPS guidance –72% in Midwest –39% in other states Source: Whipker and Akridge, 2004

GPS Auto-Guidance 5.3% of dealers use GPS auto-guidance –4.2% in Midwest and 7.4% in other states –Regional difference? Source: Whipker and Akridge, 2004

On-the-go Sensors Soil Dr – been around the longest Greenseeker Norsk Hydro N-sensor –~320 total units –~300 in Europe

Sensors for Mapping Soil pH sensor available –Veris Mobile Sensor Platform >5 sold –K sensor being developed –7.8% of dealers offer soil EC mapping* *Source: Whipker and Akridge, 2004

Fundamental Constraints of Adoption Lack of research support Human capital costs Lack of education and training

Fundamental Constraints of Adoption Lack of support and consulting High opportunity cost of management time Information-intensive / embodied knowledge

“Information-intensive” vs. “Embodied knowledge” Information-intensive Field level data to make decisions Requires additional data and skill VRT and precision agriculture IPM Embodied knowledge Information purchased in the form of an input Requires minimal additional data/skill Hybrid corn Round-up Ready or Bt

Fundamental Incentives of Adoption Technology costs are declining Incorporation of technology in society –GPS in cars and boats Increased comfort level with technology –USDA FSA and NRCS using GIS with farmers

Fundamental Incentives of Adoption Automating Record Keeping Identity tracking of commodities Pesticide record keeping Environmental regulations – monitor input use –May lead into cost sharing for adoption

Fundamental Incentives of Adoption Auto-guidance systems Increase farm size with same equipment set –Reduce overlap, expand work day, increase speed Match equipment operations (6, 8, 12 row) Controlled trafficking Strip till

Economies of Scale in Data Analysis Skill to analyze 2000 ac works for 20,000 ac Potential for PA consulting - outsourcing Complementary goods and services

Part 2: PA Profitability Review Standalone VRT fertilizer often does not cover costs –Swinton and Lowenberg-DeBoer (1998) In 2000, 63% of studies showed profits, but budget methods not standardized –Lambert and Lowenberg-DeBoer (2000) Economics of precision agriculture are site-specific

Profitability Studies to Date Reviewed 234 articles 210 reported some kind of benefit or loss Of those, 68% reported positive benefits 52% of studies involved an economist

Part 3: Better Use of Data Many farmers collecting data –10 + years and several megabytes Question remains: what to do with the data? No one has all the answers Is data valuable enough to justify processing?

Better Use of Data Better farm-level experimental designs Spatial statistical methods More reliable local information

Better Experimental Designs Small plot designs developed 70 years ago –Blocking and replications neutralize variability Precision agriculture measures variability Spatial statistics can model variability

Better Experimental Designs Opportunity for fewer replication large blocks Types of comparisons farmer tend to conduct Experimental designs being tested in 4 states Farmer feedback crucial to evaluation

64 acre field Satellite image taken in July Red outline is field boundary

Planned comparison design 3 varieties Single-block non-replicated Note: soil types are outlined in blue Each variety is represented on each major soil type/zone

Once designs are decided upon in off-season, implementation is simple at planting time Treatments can be changed at normal planter refilling times Soybean harvest can be conducted at any angle to planter pass

Yield Monitor Data Analysis Yield monitor data analysis service pilot project 37 th Annual Top Farmer Crop Workshop –July 18-21, 2004 More reliable results gained

Summary Adoption has been slow and uneven Economics well documented – many studies Information-intensive vs. embodied knowledge ag Need for analysis services to overcome constraints

Role of Extension Farm Management Third party evaluation desperately needed –Firm understanding of precision technologies Help farmers develop own recommendations instead of supplying answer –On-farm comparisons

Role of Extension Farm Management Assist farmers and ag businesses in understanding economics of information Barriers to adoption are an opportunity for extension to be more relevant
