Comment:
Fertilized LTER T8NT plots (4 plots) with potash (0-0-60) at 70 lbs/A. The 70 lbs/A potash provided 42 lbs/A K2O to the plots.
Average speed while spreading 70 lbs/A potash was 2.7 mph (B3, 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 (10:00 a.m.) were overcast, 48 degrees F, 46 % humidity, with 8 mph. SE winds. Conditions at the end (4:00 p.m.) were overcast, 57 degrees F, 27 % humidity, with 11 mph. ESE winds.
