A recent published study (Rytter et al., 2011) points to the large poplar biomass production in short time, but knowledge of management practices lacks for Nordic conditions. Individual landowners have little help or guidance in selecting the optimal time for harvesting or planting density in establishment of new plantations. This project is therefor divided into two substudies: I) study the growth of twelve poplar stands (7 to 23 years old) which provides guidance on the optimal rotation period
II ) study the growth dynamics under three diffent planting densities in two research trials, established spring 2016. Results from the two studies aims to articulate best possible management systems for optimizing the production and financial outcome.Both studies will be conducted on clone OP42 (P. maximowiczii x P. trichocarpa) on plantations established on farmland in southern and central Sweden. The stands from the two studies will be revised annually during the project.
