Abstract:
Harvesting short rotation coppice (SRC) cost-efficiently as well as high dry matter losses during storage are still matters of much concern. Equipment and techniques are being developed and some are currently available commercially. However, it does not necessarily work efficiently for farmers. In dependence to storage time and chip size determined by the cutting system used for harvest, the common SRC harvest lines supply woody biofuels of very different quality. Own experiments and investigations have shown that bigger particles are advantages for long term storage due to improved drying by natural air ventilation. Different SRC harvest technologies have been investigated under praxis conditions regarding performance, wood chip quality and storage losses. A conventional forage harvester with SRC header and a novel tractor-mounted mower-chipper has been compared at practice. Results from harvest and storage such as harvest capacities, chip size distribution, water content and temperature in storage piles as well as dry matter and energy losses after 6 month storage in piles with storage volumes of 500 m³ each have been investigated in detail. The results indicate major differences for the storage behavior of the wood chips produced with the two different harvest systems.
