National peatland database

Abstract

Peatlands each layer, with descriptions of the colour and texture of the sample. The Von Post (1922) classification system can also be used to describe the organic matter decomposition scale (i.e. H1 to H10). A peat profile can have different layers that represent different deposition environments (e.g. sand layer indicates higher energy; ash layer indicates desiccation and peat fire). In thicker peat layers, Carbon content also tends to increase with depth in a profile. A peat auger is the best tool for obtaining a peat sample. If a peat auger is not available, a shovel or a spade can work satisfactorily. Take a slice of peat (about 50x50x20 mm thick) from each layer and place it in a sample bag. Mark the sample bag clearly on the outside. Use a permanent marker pen or attach a sticker or piece of paper onto the bag. Record all relevant data on the sample submission sheet. The laboratory sample should be approximately 500 grams or 250 ml. The lab does not need a large sample but 500 g will allow repeat analyses, if required. How should one preserve the sample?
