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

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
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
Transforming information into action….

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.

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
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
Environmental Impact
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
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
