Fertilized GLBRC Main Site treatment G4, all replications (reps. 5, 4, 3, 2, and 1) with potash (0-0-60) at 150 lbs/A. The 150 lbs/A potash provided 90 lbs/A K2O to the plots. The fertilizer was applied with the JD 7420(a) tractor traveling at approximately 4.7 mph, 1600 rpm travelling in gear C2 and a Gandy Orbit-Air fertilizer applicator controlled by a Raven 6000 which monitored the application and automatically adjusted the metering rate for changes in ground speed. For the Gandy/Raven set-up, the following were used: Density 70 lbs/cu ft; metering wheel 1 1/4” diameter (yellow); deflector spacing 22”; meter cal number 199; air pressure was 12-14 p.s.i.; Boom length 30 ft, nozzles 24-30 inches above the ground level. Weather conditions: sunny, temperatures 52 degrees F, winds 6 mph from southeast (10 minute average of 8 mph), 60% relative humidity, application time 11:00-11:59 a.m.
