Comment:
Fertilized GLBRC Main Site Treatments G1-G3, all replications (1-5) with potash (0-0-60) at 250 lbs/A. The 250 lbs/A potash provided 150 lbs/A K2O to the plots.
Average speed while spreading 250 lbs/A potash was 1.4 mph (A3, 1350 rpm) with JD 7420 B and 30' 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 68 lbs/cu ft; metering wheel 1 1/4" diameter (yellow); deflector spacing 22.5"; meter cal number 199; air pressure was 11.5 p.s.i.; Boom length 30 ft, nozzles 24-30 inches above ground level.
Weather conditions at the start (9:45 a.m.) were sunny, 40 degrees F, 62 % humidity, with 10 mph. N winds. Conditions at the end (5:50 p.m.) were partly sunny 56 degrees F, 27 % humidity, with Calm. N winds.
