“…Soils were pre-incubated for 14 days at 12.5 °C to allow the microbial respiration flush from fresh organic matter 130 released due to sampling and freezing procedure to subside (Herrmann and Witter 2002). This temperature 131 corresponded to the mean air temperatures at the long-term field experimental sites during the vegetation period 132 (May-September).…”

“…In questi casi l'incremento della concentrazione di azoto inorganico nel suolo è spiegato da una riduzione dell'assorbimento radicale, danneggiato comunque dall'azione del gelo ) e dall'esposizione di superfici di scambio prima non disponibili, con il rilascio di forme di azoto organico di origine non microbica, successivamente mineralizzate (Hermann e Witter, 2002).…”

“…This variation in results from may to some extent originate from differences in freezing responses among soil and vegetation types (Lipson & Monson 1998), but it also appears that variation in FTC treatments among studies has been an important factor, with studies featuring the most severe freezing treatments typically demonstrating the most extreme results (Henry 2007). While efforts can be made to ensure that the freezing rate and intensity are realistic in soil freezing experiments (Herrmann & Witter 2002, Ferrick & Gatto 2005, the selection of realistic FTC scenarios becomes challenging in the context of climate research, because predicted changes in FTC frequency must be extrapolated.…”
