Comment:
Fertilized LTER Main Site treatment T4 all reps with Organic Granulated Rock Phosphate Fertilizer 0-20-0. The target rate in John Deere Dry Rate Controller was 110 lbs per acre. The lower rate was applied because that was all the fertilizer that the supplier had bagged at the time of purchase. Prairie strips were not fertilized. Application was done at 5.1 mph, C3 gear at 1400 engine RPM and Gandy air gauge at 19 oz/ square inch. JD Dry Rate Controller CFR was set at 0.0165, density of Fertoz was 85 lbs/cubic ft.
