WHAT: In another case of sometimes-less-is-better, researchers at UC Davis and other universities have found that lower tire pressures improve the efficiency of radial tractor tires. During a one-day Tractor Tire Pressure and Soil Compaction Workshop, farm advisors and farm tire dealers will learn how low-pressure tire inflation tends to improve fuel efficiency, make possible faster tractor speeds and significantly decrease soil compaction. While monetary savings are modest, researchers stress that they can be realized at no additional cost to the farmer. Furthermore, the reduction in soil compaction is likely to increase irrigation efficiency, reduce the incidence and severity of crop diseases, and boost efficient use of fertilizers. The workshop is sponsored by the UC Davis Agricultural Education Program and Department of Biological and Agricultural Engineering, the California Energy Commission and the Far West Equipment Dealership Association. WHEN: 9 a.m. to 4 p.m. Tuesday, Nov. 14 WHERE: University Club, UC Davis VISUALS: Field demonstrations of proper tire inflation, tractor safety inspections, and retrofitting tractors with rollover-protection structures will be presented at 1 p.m. REGISTRATION: Media planning to attend must pre-register by calling Deborah Fredrickson at (916) 752-5943. DIRECTIONS AND PARKING: Take Interstate 80 to the UC Davis exit, turning north from the off ramp onto Old Davis Road. Go past the information kiosk and turn right at the first stop sign. You'll still be on Old Davis Road. Go through the stoplight and proceed to the first stop sign, turning right onto A Street. Park in either Lot 5 or 5A. Parking is free if you leave a business card identifying yourself as a member of the news media.
