Nitrogen Conference, Improving NUE using Precision Sensing

Waseca, Minnesota, Southern Research and Outreach Center, August 7-9, 2006

The Southern Research and Outreach Center (SROC) is located on US highway 14 about 15 miles west of Interstate 35 and about 40 miles north of the Iowa/Minnesota border. Or just for those flying to the workshop, the closest major airport is located at Minneapolis-St. Paul (MSP) -- a 75 mile drive from the airport to SROC.

The 2006 Nitrogen Workshop is less than two months away. To assist you in making travel plans and us in preparing for the event, we are listing items below that should be addressed by August 1 at the latest. They are:

Title: Improving NUE Using Crop Sensing
Objectives:

To delineate components needed within functional algorithms that employ active sensors.
To develop agronomic relationships between active sensors and N management for other crops.
To share ideas and concepts relative to improved NUE for corn production.
To discuss results from the current regional project and identify improvements needed for collaborative sensor-based research.

Registration:

To register for the workshop, send name, title, affiliation, e-mail address, and phone number to Deanne Nelson at nelso191@umn.edu. All must register. To help us, earlier (by July 20) is better than later. Graduate students are encouraged to attend.

Presentations:

Within the objectives listed above, we encourage you to present your findings at the workshop. Please send your presentation title, preferred objective number, and a short 2-3 sentence description of your talk to Deanne Nelson at nelso191@umn.edu by July 27. We will prepare a program based on this information on August 1. The agenda and last minute details will be sent electronically to you at that time.

Location: Southern Research and Outreach Center

35838 120^th St.

Waseca, MN 56093-4521

- Waseca is located about 15 miles west of I35 and 30 miles north of I90 in southern Minnesota

- The SROC office and meeting area is located in a grove of oak trees on the south side of U.S. Hwy 14 ≈ 1 mile west of the intersection with MN Hwy 13 in downtown Waseca. A more complete map will be furnished at a later date.

Dates:

Monday, August 7 through Wednesday noon, August 9. We will start with a picnic dinner beginning around 6:00 p.m. on August 7. On August 8, the program will run from 8:00 a.m. through 5:00 p.m. with lunch served at noon. The program will resume at 8:00 a.m. on the 9^th and conclude with noon lunch. Breakfast on the 8^th and 9^th and dinner on the 8^th will be on your own.

Lodging:

Blocks of rooms have been set aside at four motels; two in Waseca and two in Owatonna, a larger community located about 15 miles east of Waseca. See attachment for details. Reservations need to be made by June 30 to guarantee the reduced rate at one of the Waseca motels.

This information along with updates will appear on the Oklahoma State website http://www.nue.okstate.edu as we get nearer to August 7-9. Stay tuned for thoughts and ideas regarding a raffle and other “light activities” during the workshop.

Please do not hesitate to contact the Minnesota planning and host group for further information.

Results from 2004 Workshop

Results from 2003 Workshop

Results from 2005 Workshop

In May and June, we will be soliciting topics and titles from those interested in giving a presentation or reporting your findings at the workshop.

The objectives in 2006 will be very similar to those last year.
1) To delineate the components needed within functional algorithms that employ active sensors.
2) To develop agronomic relationships between active sensors and N management for other crops.
3) To share ideas and concepts relative to improved NUE for corn production.
4) To discuss results from the current regional project and identify improvements needed for collaborative sensor-based research.
