Fertilized LTER Main Site treatment T3, microplot area only, all replications (reps. 6, 5, 4, 3, 2, and 1) with monoammonium phosphate (MAP: 11-52-0) at 60 lbs/A product. The 60 lbs/A of MAP provided 6.6 lbs/A of nitrogen and 31.2 lbs/A of PO4. Only the ”+Fertilizer” plots were fertilized (BAU+FERT, NWC+FERT, and WF+F); the ”-Fertilizer” plots were not fertilized. The fertilizer was applied with the JD 7420(a) tractor traveling at approximately 3.8 mph, 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 204; air pressure was 12-14 p.s.i.; Boom length 30 ft, nozzles 16-24 inches above the ground level. Weather conditions: sunny, temperatures 52 degrees F, winds 13-26 mph (10 minute average of 13 mph) from northwest to north, 33% relative humidity, application time 11:00 a.m. - 12:30 p.m.
