1. Use of Precision Ag in Hay and Forage Production
Jeremy Church

2. Background United States Land in Farms 938,279,056 Ac
Cropland Production
434,164,946 Ac
Forage Production
64,041,337 Ac

3. Background Oklahoma Land in Farms 33,661,826 Ac Cropland Production
Forage Production
3,084,888 Ac
2002 US Ag Census

4. Background Forage Production is Crossed 4, 5, Sometimes 6 or More.
Equates Up to 18 mil. Ac Crossed Per Year.

5. Major Inputs
Fertilizer
Fuel
Chemical
Time

6. Possible Adoption Options
GPS Guidance
Field Scouting
Grid Sampling
Production Record Maps
Variable Fertilizer Application
Sensor Technology

7. GPS Guidance
Reduction In Overlap = Less Passes Due to Less Area Covered = Less Time in Field = Less Fuel and Chemical Used

8. Field Scouting Plant Quality Field analysis; Refractometer
Soil Structure
Penetrometer
Moisture levels

9. Field Scouting Weed Locations GPS Mapping of Application Areas
Water Holes
GPS Mapping of Non-productive Locations
Reduce Application of Chemicals, Fertilizer in Bare areas

10. Grid Sampling Soil Sampling
Identification of more productive soil, problem areas, areas nutrient deficiencies, and possible shortfalls in soil biology
Plant Sampling
Identification of areas for foliar feeding

11. Variable Fertilizer Application
Integration of Grid Sampling and Field Scouting to Maximize the Use Efficiencies of Applied Nutrients by Applying Nutrients Only Where Needed

12. Variable Fertilizer Application
Utilizing N-rich Strips
And Ramp Application
Rates Allows for a better
use Efficiency and leads
to less Fertilizer used

13. Sensor Technology

14. Conclusion
Rising Cost of Inputs has Seen a Dramatic Increase in the Need for the Integration of Precision Agriculture Practices
Precision Practices will pay for themselves with the reduction of time used and with the consumption of fuel, chemical, and fertilizer
REDUCED INPUTS = INCREASED PROFIT
