Brief Project Summary:

This project develops systems and protocols to launch a large-scale implementation of the On-Field Ohio tool. It develops an automated curriculum for agricultural advisors to work with their farmer clientele to evaluate and document reductions in erosion and phosphorus runoff, along with economic costs associated with changes in practices. The objective of On-Field Ohio! is to evaluate and revise the Ohio P Risk Index as needed using field-scale, edge-of-field monitoring facilities. Efforts assist farmers to compare current management practices with alternative management practices for potential reductions in erosion and P runoff and collect information about best management practices.

Key Benefactors:
farmers, agronomists, extension agents

Information And Results
Project Deliverables

The project will be evaluated by tracking and reporting:
1) number of sites being monitored,
2) types and combinations of production and conservation practices,
3) P indices for each field being monitored using the current P Index,
4) comparison of the phosphorus indices with actual field observations/measurements,
5) utilization of new Ohio P Index once it is released.
The project participants will schedule quarterly meetings to review project objectives and timelines, discuss progress, and plan upcoming activities. Agency and farmer feedback resulting from all project activities will be captured and provided in the final report.

Final Project Results

Update:
Work completed includes:
1. Rather than having all calculations done on the dominant (having the highest % of area) soil map unit, we now run calculations on a weighted average of the all map units in the area of interest. This provides a weighted average of erosion outputs, and runoff volume estimates over a larger proportion of the field. These outputs are used by the tool in subsequent calculations, and should better represent field properties and practices. This may be especially important for heterogeneous (rolling) fields.

2. Revise On-Field Ohio! results output. To more easily compare results of multiple crop management scenarios (which we want users to do), simplify outputs and user recordkeeping by showing RUSLE2 and nutrient descriptors along with associated results outputs.

3. The “clear” button on the google map (to identify the field) page should only clear an incorrect outline, NOT push the user all the way out of the map. Frustrating to have to identify a field multiple times.

4. Repaired "bugs" in fertilizer/manure application calculations

The United Soybean Research Retention policy will display final reports with the project once completed but working files will be purged after three years. And financial information after seven years. All pertinent information is in the final report or if you want more information, please contact the project lead at your state soybean organization or principal investigator listed on the project.
