Project code: TI-WO-08-PID1419
Contract period: 01.09.2010

Purpose of research: Applied research
The most important factor for the yield of energy resource is the availability of water. Due to the dry conditions of the Thuringian Arable Plain, the use of local water resources is a necessary condition for an optimal yield of short-rotation coppices. The Thuringian basin is one of the driest regions in Germany. The irrigation of short rotation coppice (SRC) stands with biologically treated wastewater is an interesting option to compensate water shortage and to increase biomass production for energy use. The studies are aimed at examining the additional yield potentials in irrigated versus non-irrigated short rotation coppice (SRC) stands. - Development of concepts for wastewater irrgation. - Measurement of irrigation demand of short .rotation coppices (SRC) by an irrigation model ('ZEPHYR'). - Implementation of a furrow irrigation by a tank wagon. - Establishment of field plots; assessments of field ecological and yield parameter.
- Due to irrigation regime the short rotation coppice (SRC) stand could grow in the years 2012 and 2013 under optimal water supply (50% of the soil available water storage), and thus could produce high amounts of biomass. - Irrigated stands showed a higher radial and height increment than the non-irrigated ones, and produced more leaf and woody biomass.
