Fertilized LTER Main Site treatment T2, all replications (reps. 1, 4, 3, 6, 2 and 5) with potash (0-0-60) at 92 lbs/A. The 92 lbs/A potash provided 55.2 lbs/A K2O to the plots. The fertilizer was applied with the JD 7420(a) tractor traveling at approximately 4.8 mph, 1650 rpm travelling in gear C2; Gandy Orbit-Air fertilizer applicator controlled by a Raven 6000 monitor which monitored the application and automatically adjusted the metering rate for changes in ground speed.
