Extractable NH4-N and NO3-N (2 N KCl), PO4-P (0.025 N HCl) and pH (0.01 M CaCl2) were measured on soils from a transect along the Dalton road, Arctic LTER 1991.

Extractable NH4-N and NO3-N (2 N KCl), PO4-P (0.025 N HCl) and pH (0.01 M CaCl2) were measured on soils from a transect along the Dalton road. Sites are Gus Shaver flowering sites and Arctic LTER sites.

沿道尔顿公路布设的样带土壤样品中，测定了可提取态铵态氮（Extractable NH4-N）、硝态氮（NO3-N，2 N KCl浸提）、可提取态磷酸盐磷（PO4-P，0.025 N HCl浸提）及0.01 M CaCl2体系下的pH值。供试样地涵盖格斯·谢弗开花样地与北极长期生态研究（Arctic LTER）样地。
