1. It’s the Water Workshop An Industry Approach Sept. 13, 2005 Dan Froehlich US Agronomy Manager Nitrogen Management

2. Mosaic’s Approach  Focus on balanced nutrient approach  Be sure grower understands total crop needs  Soil sample, account for nutrient credits, and apply fertilizer as needed  Identify amount of field variability  Manage field variability  Document actions and results

4. FieldInSite  Benefits  Complete mapping and record keeping system 

5. FieldInSite  Benefits  Complete mapping and record keeping system 

6. FieldInSite  Benefits  Complete mapping and record keeping system 

7. Nitrogen Management  Currently use crop removal minus credits for soil test levels, previous crop, manure, OM mineralization, planned applications  Illinois ISNT test incorporation study  Incorporation of other existing nitrogen management technologies  Approach is adaptable to University and regional recommendations

8. Corporate Mandate  Develop technology that can reduce fertilizer rates 25-30% while maintaining or improving grower profitability  Technology cannot be dependent on use of yield monitor data  Dealerships are not required to have a GIS specialist to operate program  Educate growers and dealers on advantages and economics of efficient nutrient management

9. Transforming information into action…. www.FieldInSite.com

10. FieldInSite   Internet—based GIS platform  Designed to deliver solutions, not another toolbox  Allows for sharing data between the grower and those who serve them  Uses patented products designed in cooperation with NASA, USDA GEOSYS and Cargill  Over 15 years of field research

11. With all the information in the World…. ….how do you? ….gather….store ….analyze ….decide

18. 1- Define soil analyses GPS points: Select 1 to 12 points per zone Grid proposal in each zone? 2- Select type of analyses 3- Check costs of order basket 4- Send order with GPS points 5- You will receive an email when your field database will be updated with the soil analyses results and maps.

25. FieldInSite  Benefits  Complete mapping and record keeping system  Communication tool between dealership and grower  Not dependent on real time imagery, yield monitor data, or LandSat 5 only imagery  Defines field variability to facilitate intelligent soil sampling and proper nutrient placement  Variable rate applications can be done with all fertilizer products at any time  Web based system can means prescription can be changed minutes before going to the field  Prescription can be written to any controller  Manage quality traits in wheat, malt barley, corn

26. Northwest Iowa Study Two-year study 31 fields containing 3,143 acres 180,225 less lbs. of nitrogen applied 195.9 less tons of urea applied Average of 57.3 less lbs. of N per acre applied (28.7% reduction) Increased corn yields 3 bu/a

27. Environmental Impact

28. Grants and Studies – Current Year  Chesapeake Bay watershed grant – evaluate the effectiveness, economics and feasibility of variable rate nitrogen applications in the Chesapeake Bay area  Pennsylvania watershed grant – evaluate variable rate technology as a means to lower nutrient loads to the watershed

29. Grants and Studies – 2006  Montana – CIG grant to evaluate economics and feasibility of variable rate nutrient application  North Dakota – CIG grant to evaluate economics and feasibility of variable rate nutrient application
