| Abstract/Contents: | "Bermudagrass (Cynodon dactylon L.) is established on athletic surfaces in the Southeastern United States because it has good wear tolerance and excellent recuperation. However, during bermudagrass establishment in sandy soils, nutrients are prone to leaching due to high hydraulic conductivity and low CEC. Poultry litter ash (PLA), a byproduct from power plant electrical production, has been reported to be a sufficient P source with reduced P leaching in horticulture nursery crops. Therefore, the objectives of the study were to evaluate poultry litter ash (PLA) compared to triple superphosphate (TSP) as a P source for bermudagrass and P leaching potential over a range of PLA:TSP proportions (100:0, 75:25, 50:50, 25:75 and 0:100). The study was conducted over 6 weeks in a greenhouse in Baton Rouge, LA using columns (10 cm diameter; 20 cm depth) packed with 90% sand and 10% peat. The upper 10 cm of soil was incorporated with combinations of PLA and TSP fertilizers. Bermudagrass was seeded into each column with irrigation applied daily to replace 100% ET. Bermudagrass coverage was estimated at 3 and 6 weeks after planting (WAP) and biomass measured at 6 WAP. Leachate was collected each week and analyzed for P. PLA at 100%, 75%, 50%, and 25% reduced cumulative P losses by 46%, 39%, 40%, and 7% compared to bermudagrass fertilized with 100% TSP. Phosphorus leaching was highest initially and decreased over time. Bermudagrass coverage was >75% 6 WAP for all fertilizer combinations. Thus, PLA reduced P leaching and provided adequate P fertility for bermudagrass establishment in a sandy material. Because there were no negative effects on bermudagrass establishment and leaching was reduced at 100% PLA, PLA applied alone may provide a slow-release P source for bermudagrass grown in soils prone to leaching." |
