Coltivazione di legna da combustione

Dalla fine di Marzo fino al massimo a metà Maggio (alta quota) Infilare nel terreno a circa 20 al massimo 50 cm di profondità: talee (circa 20 cm), canne (1 – 2 m) o barbatelle radicate di un anno (1 – 2 m). Piantare e premere bene sul terreno. Distanza tra le piante a una […]

Energy forest

  Energy forest is a term used for the cultivation of fast-growing trees, mostly poplars, willows, and robinias, on cropland or pastureland. The harvest (also referred to as “stock”) takes place, not like with “conventional” forest, only once in 30-100 years, but within 2-10 years, depending on the system and planning. An energy forest sprouts after harvesting (ground-level pruning) again and can be […]

Rese della foresta energetica

La resa per ettaro all’anno ammonta a circa 7 fino a 15 tonnellate atro (assolutamente asciutto = massa asciutta). Ci possono tuttavia essere delle differenze anche molto sognificative in base al clima, lo stato del terreno, l’approvvigionamenti idrico e le varietà. Nel caso del pioppo, in presenza di condizioni ottimali la resa può ammontare fino […]

Warum auf Kurzumtriebswirtschaft setzen?

Erste Versorgungsschwierigkeiten durch die steigende Anzahl an Biomasseheiz(kraft)werken und ebenso Kleinfeuerungsanlagen im privaten Bereich sowie auch gleichzeitig steigender Bedarf der Zellstoff-, Platten- und Sägeindustrie lassen die Suche nach Alternativen zum herkömmlichen Energieholz aus dem Wald aktueller denn je werden. Durch einen Energiewald können andererseits auch unterdurchschnittliche Flächen sinnvoll genutzt werden, eine Alternative zur oftmals wenig interessanten Verpachtung geschaffen werden, sowie die lukrative Möglichkeit für Zusatzeinkommen von landwirtschaftlichen Betrieben ermöglicht werden. Zudem ist das Thema Unabhängigkeit und Versorgungssicherheit heute für jeden in die Zukunft schauenden Landwirt ein ganz wichtiger Punkt.

Willows

Especially in Sweden, experts have been breeding willows for the cultivation of energy woods. We also sometimes hear about sporadic initiatives from Poland, Italy and England; however, we have not had any experience with them so far. Willows are more suitable for short-term to medium-term rotations, such as 2-7 years with the stocking of about […]

Wood chips

(See also Chips) Producing wood chips from energy wood in short rotation faces two fundamental challenges: Fine or bark content in wood chips Water content Exactly, the bark content in willows in short rotation is relatively high, which decreases the quality of goods. Basically, the bark content reduces in total wood chips, the thicker the trunks are in harvesting. […]

Wood fuel

We use the term of “wood fuel” not only for biomass from short rotation / energy forest, but also any wood from “natural” growth, such as from forests, which issupplied for energy purposes. With the increased use of wood for energy purposes (energy wood, or wood fuel), it also came to a competitive situation on the timber market in recent […]
