Cultivation models

In addition to the traditional model, we operate the cultivation model called Short Rotation Forestry and the Medium Rotation Forestry model

PRODUCTION SYSTEMS

SRF CULTIVATION MODEL

Short Rotation Forestry

The SRF (Short Rotation Forestry) cultivation model is the cultivation for the production of short-cycle biomass, mainly chipped for energy uses or as an industrial material, of rapidly growing hybrid poplars which, planted with a high degree of density (6,000 – 7,000 plants per hectare) and managed with suitable cultivation techniques, are harvested with cutting cycles of two to three years.

MRF CULTIVATION MODEL

Medium Rotation Forestry

The MRF (Medium Rotation Forestry) cultivation model has slightly longer cycles than those envisaged in the SRF system, (4-6 year cycle), and the plants have a lower density (~1600 plants per hectare).

For both SRF and MRF, plantations have a lifespan of 12/15 years, as the stumps are able to reproduce after cuttings.
