Fertilizer Application |
(first entry) I spread triple superphosphate (0-46-0), potash (0-0-62), and boron (B) fertilizers to treatment 6 replications 1, 2, 3, 4, 6, & 5. Actual amounts applied on the 15 acres (6 ha) were 3,920 lbs (1,782 kg) of 0-46-0, 5,990 lbs (2,723 kg) of 0-0-62, and 50 lbs (22.7 kg) of boron. The fertilizers were blended together and applied at the same time. The fertilizer was applied with a JD 7400 tractor, C3 1700 rpm, around 6-7 mph, and a Willmar 6 ton pull type spinner spreader. With a spinner spreader it would have been difficult to spread, in one pass, the entire amount of fertilizer recommended. The pattern of the fertilizer coming out of the spreader may not be a uniform pattern at such a high rate of fertilizer per acre therefore; I split the application rate in half then drove over the plots twice. The driving intervals were based on a 40 ft spreading pattern. The second time over the plots I drove between the first set of driving intervals. After spreading fertilizer on all six replications I had some fertilizer remaining in the spreader (about 1,992 lbs) so I applied the remaining fertilizer onto replications 1, 2, and 5, i.e. I did not change the setting on the fertilizer spreader and I went over reps 1, 2, and 5 for a third time. Replications 1, 2, and 5 had the lowest amount of P and K in the soil, i.e. the highest fertilizer recommendations was for reps 1, 2, and 5. Actual amounts applied to replications 1, 2, and 5 (7.5 acres, 3 ha) was 2,352 lbs (1,069 kg) of 0-46-0, 3,594 lbs (1,634 kg) of 0-0-62, and 30 lbs (13.64 kg) of boron. In replications 1, 2, and 5 the 314 lbs/A of 0-46-0 provided 144 lbs/A (161.7 kg/ha) of P2O5. The 479 lbs/A of 0-0-62 provided 297 lbs/A (333 kg/ha) of K2O. The 30 lbs of boron provided 4 lbs/A (4.5 kg/ha) of boron. Actual amounts applied to replications 3, 4, and 6 (7.5 acres, 3 ha) was 1,568 lbs (713 kg) of 0-46-0, 2,396 lbs (1,089 kg) of 0-0-62, and 20 lbs (9 kg) of boron. In replications 3, 4, and 6 the 209 lbs/A of 0-46-0 provided 96 lbs/A (107.8 kg/ha) of P2O5. The 319 lbs/A of 0-0-62 provided 198 lbs/A (222 kg/ha) of K2O. The 20 lbs of boron provided 2.6 lbs/A (2.99 kg/ha) of boron. |
