Comment:
Fertilized GLBRC Main Site treatment G3, all replications (reps. 5, 3, 2, 4, and 1) with potash (0-0-60). Plots were fertilized at different rates based on soil testing from 2011. The plots (both main plot area and microplot area) were fertilized according to the following schedule (weights in lbs/A): rep 1 - 275; rep 2 - 300; and reps 3, 4, and 5 - 250. The following amounts of K2O were supplied to the the plots (weights in lbs/A): rep 1 - 165; rep 2 - 180; reps 3, 4, and 5 - 150. 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 1:30-3:00 p.m.
