Fertilized the LTER Main Site Treatment T6 alfalfa, all replications (reps 6, 5, 4, 3, 2, and 1) with phosphorus. A total of 200 lbs/A of product was applied which supplied 92 lbs/A of P2O5. Applied in a single application of using the John Deere 7420a tractor traveling 4.3 mph (range B3, 1350 rpm) and a 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 60 lbs/cu ft; metering wheel 1 1/4” diameter (yellow); deflector spacing 22”; meter cal number 210; air pressure was 13-14 p.s.i.; Boom length 30 ft, nozzles 16-24 inches above the ground level.
