| Abstract/Contents: | "Analyses of golf green rootzone samples submitted by golf clubs were evaluated to asses the effect of soil nutrient levels and balances on species composition of golf greens. Samples were analysed for pH, available P and exchangeable Ca, Mg, K and Na. The visually assessed compostition of golf greens was placed into three categories; >90% Agrostis capillaris, >90% Poa annua, and mixed species. Poa annua was significantly more likely to be found at high pH. Descriptive evidence showed that Agrostis capillaris was most abundant at lower soil fertility (pH < 4.8, K < 2-3%BS,Mg < 4-5%BS, Ca < 18-19%BS, and P < 8 mg/l). Poa annua was most abundant on rootzones of low cation exchange capacity and high pH and bases status. Agrostis capillaris occupies the niche of a slower growing, but more efficient user of nutrients that are in short supply, while Poa annua can utilise abundantly supplied nutrients for rapid growth." |
