Abstract:

Peat cores were taken in late August, 2016, with a box-shaped 65 mm x 37 mm peat corer, except in the wet TP site where a 60 mm x 60 mm corer was used. One core per plot = three cores per site were taken. The cores were divided into 10-cm segments from soil surface to 50 cm depth. Peat pH and bulk density were determined for each segment. For nutrient analyses, the segments representing the same depths from the 3 cores per site were combined and homogenized by milling. Drying temperature was 70 °C, and the dry matter content was estimated with a subsample dried at 105 °C.
