Comment:
Fertilized GLBRC Main Site treatment G2, all replications (reps. 4, 1, 5, 2, and 3) with potash (0-0-60). Plots and microplots were fertilized at different rates based on soil testing from 2011. All the main plots were fertilized at 250 lbs/A potash which provided 150 lbs/A K2O. The following amounts of K2O were supplied to the microplots (weights in lbs/A): rep 1, 2, 4, and 5 - 250; rep 3 only - 50 (50 lbs/A potash supplied 30 lbs/A of K2O). The fertilizer was applied with the JD 7420(a) tractor traveling at approximately 2.5 mph 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 59 degrees F, winds 7 mph from south southwest (10 minute average of 9 mph), 48% relative humidity, application time 3:00 - 4:30 p.m.
