Missouri Strip Trial Program
Farmer led & farmer focused.
Applied research/trials….“on-farm”.
Practical info & results for farmers.
Deliver results quickly – for next growing season.
• Strategies for low altitude, high resolution data collection (e.g. SDS identification)
• Image analysis: Stand counts, Plant color, Ground cover
Data collection and translation into results
• Yield map protocol handbook
• What information is required and how best to obtain and organize?
• Appropriate statistical methods: single farm, across locations and years.
• Efficiently translating results into reports to farmers.
Scouting: Documenting K deficiency in Soybean
65 feet with 4:3 aspect ratio – moving UAV
65 feet with 5:4 aspect ratio – stationary UAV
300 feet with 5:4 aspect ratio – Stitched image - moving UAV
Documenting cover crop: % cover, weed pressure.
Commercial product – from an airplane – 4/11/17
300 feet UAV Stitched image – 5/5/17
3 feet IPAD image – 5/8/17
The role of soil sampling
• Current Projects• Soybean Cyst Nematode
• Soil test phosphorus.
• Cost vs. Opportunity• Scale issues
• Expensive to obtain – in time and $$
• Timing an issue – For SCN we are sampling before strips are planted.
Data Carpentry • Which are the full swaths?• Is swath width correct?

Image Processing • Automate pixel recognition.• What is plant? What is soil?
• Develop tools in accessible software.• ArcMap and QGIS
• Goals? • N status/Residue cover/Weeds/pressure/Population.
Method: ManualRed/Green Ratio
Method: AutomatedK-means on ExG vs. V space

Developing technical approach – in progress
Data standards
• Insuring trials are uniformly implemented across farms.
• Standardizing processing and organization of data.
Developing analysis and reports
• Goal to reach out to farmers at least three times after trial is established.
• What metrics and reports are effective?
Combining data among locations
• Working with Iowa On-Farm Network and Cornell University to consider spatial and Bayesian statistical methods.
Case Studies from 2017• ILeVO
•Cover Crop
•PhosphorusReview of preliminary results from example trials.
MU Extension, the Missouri Soybean Merchandising Council and the Missouri Corn Merchandising Council.The MU Certified Strip Trial Program is funded by:
Cover Crop Termination Date: Cover crop Terminated at two different dates in spring
Phosphorus: Crop response to phosphorus fertilizer
Nitrogen: Grain Crop response (corn, milo, wheat) to nitrogen
ILeVO: ILeVO high rate vs. no ILeVO
For more information, contact your local Extension office;Theresa Musket at 573-884-8696 or [email protected]; or
Trials are conducted on Farmers’ fields and designed to work with the Farmers’ own equipment.
MU Certified Strip Trial ProgramHelping farmers validate management decisions on their farm while documenting efficiency and environmental stewardship.
Trial Options for 2018 (some are tentative*)
Cover Crop Trial: Termination date ahead of corn or milo – nitrogen focus.
Cover Crop Trial: Termination date comparison.
Phosphorus Trial: Response to phosphorus fertilizer.
Nitrogen Trial: Assessing fall, winter or spring N application for corn & milo.
Nitrogen Trial: Assessing N decision support tools for corn and milo.
Nitrogen Trial: Nitrogen response of grain crops (corn, milo, wheat).
Seed Treatment Trial: ILeVO test trial*.
Pesticide Trial: Foliar fungicides*.
Cover Crop Trial: WW-CC-Con comparison.
Cover Crop Trial: Cover crop options following soybean prior to corn.
Details of these trials with the exception of the last three follow. Note that the last two cover crop trials have already been initiated for 2018.
