Progress report on planting willows and poplars
Mr. Woisetschläger has transformed a part of his green spaces together with us into an energy area and is providing his first feedback now, 3 years after planting.
First, however, some project details:
His property located at 800 m above sea level is already relatively high for an energy forest planting and, from our experiences, does not suit for all energy plants. In this particular case, the soil was also rather below average. Moreover, the rocky soil provided some additional difficulties for planting. However, since the own forest could not cover the in-house needs, the owner was looking for other opportunities. And so it came to a “fruitful” cooperation with Energiepflanzen.com.
Not quite a hectare was planted with willows and poplars.
The most wood materials were the Swedish willow clones of 3 varieties – Tora, Tordis, and Inger. A smaller part of the area was planted with Max 4 poplars.
Due to the circumstances, it was agreed to plant the wood fully automatically in spring, using a planting machine.
We organized planting accordingly.
The plant population was chosen for medium-sized rotation, i.e. 3-5 years, and the row spacing supports harvesting with a harvester.
In the year of planting, the shoots were healthy, and it was impossible to distinct between poplars and willows yet.
However, after 3 years, it all looked quite differently: You can see that willows grow optically better than poplars. So, after 3 years, the willows were harvested with a harvester for the first time.
The result was quite good: The willow area of 0.6 hectares was harvested that year, and Mr. Woisetschläger obtained over 10 oven-dry metric tons of wood chips! The chips are dried using the waste heat of the own photovoltaic plant. This provides him with he wood chips of a very good quality.
