Tiivistelmä
The demand for mechanized tree planting is expected to increase in the future. This
dissertation assessed mechanized tree planting in Finland and suggests ways to improve its
current productivity. The work on which this thesis is based was described in five peer-reviewed
articles (I–V) addressing four specific research questions (SQs) that focus on
productivity and cost-competitiveness, automation, capacity utilization, and the quality of
planting work.
While productivity of mechanized planting is higher than manual methods, it is not yet
cost-competitive. However, increasing efficiency by skilled operators and worksite
selection make it possible for mechanized planting costs to remain lower than those of
excavator spot mounding followed by manual planting. Increasing productivity and
reducing operating costs are possible with an effective automatic seedling feeding system,
although the Risutec APC is not yet sufficiently developed to reach that goal. Planting
machine capacity is underutilized and could be utilized more effective to enhance
productivity and cost-efficiency. Technical availability of planting machines in Finland is
good, and the quality of mechanized planting work is high. Optimization and integration of
the entire mechanized planting chain from the nursery to outplanting is important to
minimize total cost.
In summary, for mechanized planting to be effective the following criteria must be
satisfied: machine reliability; highly-skilled machine operator; suitable worksite; seedling
quality, availability, and supply to worksite. In the future, it is important to continue
developing new and existing machines to enhance productivity, e.g., by continuously
working planting machines.
