| Abstract/Contents: | "Researchers at Auburn University conducted a two-year investigation into the effects of application rate (180 versis [versus] 360 lb P2O5 per acre) and application method (surface or sub-surface applied) on the ability of phosphorus to leach through a sandy rootzone. The study's findings included: Leaching of P may occur in sand-based putting greens. There were no agronomic or environmental benefits to sub-surface application of P fertilizer. Uptake of P and clipping yield were better when P was broadcast applied than when the P was band applied. Applying a 2x rate of P fertilizer never improved grass establishment, clipping yield, shoot yield, or P retention in the rootzone. Application of P at a 2x recommended rate makes no agronomic or environmental sense. When applying P fertilizer to a sand-based putting green, use smaller amounts applied at a more frequent interval, using soil-test recommendations." |
