2006 soil N credit – test results

Editor’s note: This article is from the archives of the MSU Crop Advisory Team Alerts. Check the label of any pesticide referenced to ensure your use is included.  

Results for the PSNT (Presidedress Soil Nitrate Test) show significant nitrogen credit can be taken to reduce the amount of nitrogen to apply in about one-third of the samples tested by the MSU Soil & Plant Nutrient Lab. There is a moderate credit for another one-third and for the other one-third the credit is rather low. Table 1 shows the distribution of soil N credits from the PSNT.

2006 Ag Expo returns to MSU July 18-20

Farmers, educators and families are invited to Michigan’s largest agricultural equipment exposition July 18-20 when the 27th annual Ag Expo takes place at Michigan State University (MSU).

The exposition will feature a skid-steer ride and drive, zero-turn mower demonstrations, utility vehicle ride and drives, livestock handling demonstrations, an antique and garden tractor pull (July 19 only), a toy tractor show and an FFA tractor driving contest.

More than 250 commercial exhibitors, including equipment, seed, fertilizer, building and service suppliers will be on site. Visitors can expect to see tractors, implements, trailers and other equipment, and can talk to representatives from manufacturers, dealers and agencies.

“This year’s Ag Expo will offer visitors the opportunity to see new equipment and demonstrations, and we’ve brought back the popular toy tractor show along with a tractor pull event,” says Kirk Heinze, Ag Expo director.

Ag Expo will also feature a number of educational exhibits from MSU colleges and departments. The College of Agriculture and Natural Resources will host a tent with displays and information from the Michigan Agricultural Experiment Station, the MSU Land Policy Program, the Animal Science Department, Project GREEEN (the plant industry initiative at MSU), 4-H Youth Development, and the IPM Program.

Ag Expo features commercial farm equipment from throughout the Midwest and several Canadian provinces on the 35-acre main exhibition site and the 40-acre field demonstration area.

The event runs from 9:00 AM to 4:00 PM, July 18, 8:00 AM to 7:00 PM July 19, and from 8:00 AM to 3:00 PM July 20. Admission to the grounds and parking at Farm Land and Mt. Hope Road are free.
