Comment:
Fertilized LTER Main Site treatment T1, and T2, all replications 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 was 4.5 mph (C2, 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 10 p.s.i.; Boom length 30 ft, nozzles 24-30 inches above ground level.
Weather condtions at the start (8:30 a.m.) were sunny, 44 degrees F, 92% humidity, with calm N wind. At the end of application (3:30 p.m.) it was mostly sunny, 60 degrees F, 45% humidity, with N, NW winds of 5-7 mph.
