Comment:
Fertilized LTER Main Site treatment T1, T2 and T3 all replications with potash (0-0-60) at 150 lbs/A. The 150 lbs/A potash provided 90 lbs/A K2O to the plots.

Average speed while spreading was 3-3.5 mph 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.
