Comment:
Fertilized LTER Main Site treatment T6, all replications (1, 2, 3, 4, 5, 6) with potash (0-0-60) at 500 lbs/A. The 500 lbs/A potash provided 300 lbs/A K2O to the plots. The 500 lbs/A of potash was applied in two separate applications where 250 lbs/A of potash was applied at each application. First application of 250 lbs/A of potash was applied to reps 1-4 on April 21, 2014 and reps 5 and 6 were fertilized on April 22, 2014. Second application of 250 lbs/A of potash was applied to reps 1-4 on April 22, 2014 and reps 5 and 6 were fertilized on April 23, 2014. Average speed while spreading was 1.4 mph (A3, 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 (7:40 a.m.) partly sunny, 44 degrees F, 79 % humidity, with 9 mph. NNW winds. Conditions at the end (3:00 p.m.) were partly sunny 50 degrees F, 58 % humidity, with 15 mph. NW winds.
