Responses of soil extracellular enzymes to nitrogen and phosphorus additions between temperate and subtropical forests
Description
The study was conducted at Changbai Mountain temperate native forest (hereafter “CB temperate forest”, 42°24′2′′N, 128°05′42′′E) and Dinghu Mountain subtropical secondary forest (hereafter “DH subtropical forest”, 23°9′41′′N, 112°32′36′′E). We measured soil physiochemical properties and extracellular enzyme activities involved in the degradation of soil organic C, N, and P. Five hydrolase activities including β-1,4glucosidase (βG), β-1,4-xylosidase (BX), cellobiohydrolase (CBH), β-1,4-N-acetylglucosaminidase (NAG) and acid phosphatase (ACP), and two oxidase activities including polyphenol oxidase (PPO) and peroxidase (PER) were assayed. All enzyme activities were calculated based on substrate decomposition rate (nmol g-1 h-1). The datasets of soil physiochemical properties and extracellular enzyme activities are provided here.
