Comment:
Fertilized LTER Main Site treatment T3, all replications (1, 3, 2, 4, 5, 6) with potash (0-0-60) at 70 lbs/A. The 70 lbs/A potash provided 42 lbs/A K2O to the plots. (MICRO - PLOTS were not fertilized at this time.) 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.
