| Abstract:
In recent years, concern has been expressed at the potential impact that high nutrient application programmes on golf greens may have on water quality arising from large amounts of nutrients that may be lost through leaching and runoff. Furthermore, there are environmental concerns such as eutrophication that this practice may induce. Thus, the concept of reduced nutrient inputs into intensively managed turfgrass systems, such as on golf greens, has gained attention. This research was focussed towards determining the influence of reduced nutrients on leaf tissue nutrient concentrations in the grow-in year of a golf green managed to USGA specifications. Results showed that recommended nutrient rates for the grow-in year under Irish climatic conditions could be reduced by at least one-third without severely reducing turfgrass tissue nitrogen, phosphorus, potash, iron and magnesium concentrations. | |
