Demonstration trial Wulfener Bruch/GermanyThe receptor site Wulfener Bruch (11° 55' 50'' E, 51° 50' 34'' N) is located in the glacial valley of the river Elbe, c. 20 km east of the city of Bernburg at an altitude of 52 m. The climate is continental with only 462.5 mm average annual precipitation and a mean yearly temperature of 9 °C. The substrate consists of floodplain loam above deep carbon-rich fluviatile sand; the soil is a eutric Gleysols (Humusgley). For many years, the area was used as arable land, mainly for maize cultivation. The study site has an extension of 1 ha and the trial was realised on 0.78 ha. OSTsowing of seed-rich material from on-site threshing, first cut, 21 g per m²; ratio donor : receptor site c. 3 : 1, harvesting 7th September 2009, application 18th September 2009. GHapplication of Green Hay, first cut, c. 1700 g dry weight per m²; ratio donor : receptor site c. 3 : 1, harvesting and implementation 18th and 29th September 2009. OST +S, GH +SOST and GH variant with additional sowing of target species (low growing species, very early respectively late flowering species) with seeds from local origin (seed propagation or collection). In total, 17 species were sown with a density of 0.8 g seeds per m² (= c. 556 seeds per m²). On the receptor site, the sown area reached in total 3900 m² (12 x 325 m²). The seeds were sown before application of OST and GH on 18th September 2009.
