potential enzyme activity
Soil properties and chemical composition and extractable nutrients: Extractable NH4-N and NO3-N (2 N KCl), PO4-P (0.025 N HCl) and pH (0.01 M CaCl2); Carbon, nitrogen and phosphorus content; thaw depth; del C-13, del N-15; ergosterol concentration for soils near Toolik, along the Dalton Highway and Abisko, Sweden.

Soil samples were collected from control, and N+P plots from within a set of treatments in Arctic LTER Moist Acidic Tundra plots established in 1989 and in 2006 . At the time of sampling the soil was separated into organic horizon, organic/mineral interface, and the upper 5cm of the mineral soil. In the lab the potential activities of seven hydrolytic enzymes was determined using fluorometric techniques (Saiya-Cork et al. 2002) modified following Steinweg et al(.2012). |
