Peat auger

PEAT AUGER (EN: peat drill, peat auger; DE: Torfbohrer; FR: fleuret à tourbe, sonde à tourbe; ES: barrena de turba, sonda para turba; RU: бур торфяной) is the hand tool for the measurement of the total thickness of the peat deposition, of the depth of embedment of the wood inclusions within this peat deposition, and also for the layer-wise extraction of the samples of the peat from this peat deposition. The shuttle of the peat auger cuts-out the sample (core) at the certain depth, and extracts this sample from the deposition. For the determination of the depth of plunge of the shuttle, the rod, which is assembled of several sections, is sub-marked into the sections of 0.25 metres each. Depending on the purpose, the peat augers are equipped with the probing or sample-extracting shuttles.

They use the peat auger with the probing shuttle prevalently during the measurement of the thickness of the peat deposition, and during the measurement of the depth of embedment of the wood inclusions within this deposition. The probing shuttle has the small (in comparison with the sample-extracting shuttle) cross-section, and easily penetrates not only into the peat, but also into the mineral depositions, which are underlying the peat deposition, but does not ensure the preservation of the natural structure and humidity of the samples.
