Microbial biomass-C [MBC] (1) arable Cambisols (100%), (2) cut and grazed grasslands (547%), (3) forest mineral horizon A H : 0-50 mm (783%) and (4) Norway spruce forest floor (2421%). The ratio EC-Ca/EC-K reached on average 62% and ranged from 48% to 74%. Correlation between EC-K and EC-Ca values is connected with soil organic ma�er status; the correlation was very close for Cambisols (r 2 = 0.925), a medium correlation was found for forest floor (r 2 = 0.380) and a weak correlation was observed for Podzols (r 2 = 0.042). The correlation between MBC-K and MBC-Ca was very close in all cases: Cambisols (r 2 = 0.811), Podzols (r 2 = 0.904) and forest floor (r 2 = 0.496). The ratio between organic carbon and organic nitrogen in 0.01 mol/l CaCl 2 extracts [EC-Ca/N org ] could be declared as a new indicator for soil microbial association status.
Atmosférická koroze a klasifi kace agresivity atmosfér je dlouhodobým předmětem studia SVUOM. Ve spolupráci s CGS byly v roce 2001 vytvořeny mapy korozních rychlostí a korozních tříd pro uhlíkovou ocel, patinující ocel, zinek, měď, bronz a hliník. Tento článek uvádí aktuální přístup k modelování atmosférické koroze v České republice, který je založen na modifi kovaných funkcích zahrnujících klimatická data, znečištění ovzduší a nově i vliv rozmrazujících solí v okolí dálnic.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
