1 Off the Shelf Precision Ag Software Its Utility for On-Farm Research Kent Shannon Natural Resource Engineering Specialist Boone County Columbia, MO

2 Background In the past one tool available for implementing on-farm research was Enhanced Farm Research Analyst (EFRA).

3 Background EFRA extended the capabilities of ESRI ArcView GIS to accommodate tasks needed for in field scale experimentation through a variety of tools.

4 Project Objectives Evaluate two commercial precision agriculture software packages using the following criteria: The ability to create experimental plots either strips or blocks. How yield monitor data can be processed to obtain individual plot yield means for the purpose of statistical analysis.

5 Materials and Methods Software packages to be evaluated: Ag Leader SMS TM Advanced Farm Works TM Mapping and Surface Note: At this point in time only Ag Leader SMS TM Advanced has been evaluated

6 Materials and Methods Software chosen based on the following criteria: Ability to process soil sample data Develop fertility recommendation maps Create soil sampling grids (utilized for the design of plots) Process yield monitor data

7 Examples of Implementation Strip Trial Utilizing Yield Monitor As Primary Data Collection Tool Strip Trial Utilizing As-Applied Data and Yield Monitor For Data Analysis

8 Examples of Implementation In-field Plots Utilizing Detailed Plot Map Application Map As-Applied Data Yield Monitor Data Utilizing GPS as a Tool for Collecting In-Field Data Collection Efficiency
