Journal of Quaternary Science, EarlyView.ABSTRACT Upland farming in Europe is frequently assumed to have been limited and precarious, despite relict spade‐dug ridges providing firm evidence of past crop growing. Direct evidence for crop types in post‑Medieval to Modern (~since 1500 CE) uplands is rare; yet, in Ireland, relict spade‐dug ridges that date to this period are commonly interpreted ...

Fen fertilization with potash in the light of tests at Leteensuo experimental station
Agricultural and Food Science, 1960 On the fen area of the Experimental Station of Leteensuo, with a peat layer consisting of forest sedge peat, potassium fertilization produced a considerable increase of the hay crop yield on the clayed as well as the unclayed bog, when phosphate ...

The future stability of upland blanket peat following historical erosion and recent re-vegetation [PDF]
, 2005 The importance of fluvial dissection in upland blanket peat erosion is well-established but knowledge of the significance of peatland gully system development is limited. This thesis investigates the stability of upland blanket peat in relation to recent

Journal of Quaternary Science, EarlyView.ABSTRACT An understanding of the terrestrial extent, retreat dynamics and climate–glacier coupling of ice masses during the Last Glacial Termination (LGT, ~18–11 ka) is often limited by a fragmentary geomorphological record and is dependent on precise, accurate and robust dating frameworks.

Journal of Quaternary Science, EarlyView.ABSTRACT Central Australia's ngarrawa, or ‘mound springs’, are unique hydrological systems that serve as some of the only near‐permanent sources of water and continuous sediment deposition in Australia's arid interior. As such, they hold significant potential as palaeo‐climate and ‐environmental archives in a region where many aspects of past climate ...
