The role of these ecosystems in continental and Mediterranean climates though, is not yet clearly understood because environmental limiting factors and management intensities can strongly influence the overall C budget. The aim of the present study is to improve the understanding of the mechanisms underlying C fluxes in a turfgrass ecosystem and to assess its C sequestration potential by estimating the annual C budget. NEE (Net Ecosystem Exchange) of turfgrass was calculated in its seasonal variation over one year, and compared between areas characterized by different degrees of maintenance. The C sequestration potential of the turfgrass was investigated in a golf course near Verona (Italy), adopting a small-chamber enclosure approach. The measurements of gas exchanges between biosphere and atmosphere, permitted to estimate the NEE, as a function of different management intensities. The intensity of management seems to have influence on its C balance. This study needs further research to understand which maintenance variables are determinant on turfgrass C sequestration.展开更多

Authors studied two samples: the first with totally modified top soil following the USGA (United States Golf Association) Specifications, all new top soil, as in USGA, called the Texas method; the second sample was natural soil mixed with ammendants and sand, in order to reduce compaction. This study compares the initial investments, performance during training and finally the cost of maintenance. The drainage system was the same for both samples.展开更多
