Cloudberry cultivation in cutover peatlands: hydrological and soil physical impacts on the growth of different clones and cultivars
Cloudberry (Rubus chamaemorus L.) cultivation is receiving increasing attention as a means of revitalising regional economy and rehabilitating cutover peatlands. The study reported here investigated the necessary soil physical and hydrological conditions, the compatibility of cloudberry cultivation...

Cloudberry (Rubus chamaemorus L.) cultivation is receiving increasing attention as a means of revitalising regional economy and rehabilitating cutover peatlands.

Terraces at two levels were landscaped in peatland after vacuum extraction of peat to create different growing conditions in terms of hydrology and soil properties, then planted with two Norwegian cultivars (Fjordgull and Fjellgull) and two local (east Canadian) clones of cloudberry in a randomised block experiment.
