Abstract/Contents:Discusses a Swedish study following nitrogen flows in a golf green, such as nitrogen leaching, nitrogen removal with the grass clippings, and nitrogen stored in the soil, as well as to calculate nitrogen balances. States that "Agrostis stolonifera was grown in sand dominated rootzone mixtures with different contents of organic matter (2 to 4%). Nitrogen was added as NH4NO3 with a total application of about 2 kg 100 m-2 per season (April to October). Sampling was carried out during three 14-day fertilization cycles in 2001, 2002, and 2003." Also states that drainage water was collected daily or every second day, biomass production was measured daily or every second day, and soil samples were collected on the first and last day of each fertilization. Provides charts showing the results of the study and states that "time sampling was the dominant factor explaining 96.8% of the variations in biomass production," nitrogen concentration in the grass was constant, and removal showed the same trends as biomass production. Also states that the differences in biomass production "may be attributed to environmental factors such as temperature and light. At high latitudes as in Scandinavia, light limits growth late in the season while temperature is often the more limiting factor in the spring." Concludes that, during the three-year study, biomass production declined, nitrogen lost by leaching was largest in June and September 2001, and in May 2003, and removal with grass clippings was the largest nitrogen flow and strongly influenced other nitrogen flows, such as leaching.
