Abstract/Contents: | "Research at Auburn University was initiated to determine the effect of P rate and P placement on P uptake, extractable soil P, and turf performance in two hybrid bermudagrass (cv 'TifEagle') putting greens. The study found: In both years of the study, Mehlich extractable soil test results indicate that, according to those recommendations (P at 130 lb P2O5 acre-1), additional P fertilizer was needed 3 to 5 months after the initial P application. Application of P in excess of recommendations (195 and 260 lb P2O5 acre-1) did not appear to be prone to downward movement (0-12 inch sampling) within the one-year period of evaluation. Shoot density, dry weight of roots (0- to 3-inch depth), clipping yield, and P uptake by bermudagrass all increased as P rate increased, typically up to a P fertilization rate of 195 lb P2O5 acre-1. The method of P application (band or broadcast) rarely affected extractable soil P, and the only agronomic factor which was affected was P uptake by bermudagrass. In that case, bermudagrass growing in plots which received banded P had greater uptake of P than bermudagrass growing in pots with broadcast P. Phosphorus fertilization of sand-based greens should not be neglected, and slightly higher rates (or more frequent application) than that recommended by current AL soil-test recommendations may be warranted. Additional research is needed in this area to make sure that long-term environmental impacts via P accumulation do not develop." |
