Grassland yield and quality, leaf litter input, and wood yield in a short rotation coppice agroforestry systemin Lower Saxony, Germany, in 2015, 2016, and 2017

Data were collected at a short rotation coppice agroforestry site established at Mariensee (Lower Saxony, Germany) in 2008. At this site, three 10 m wide willow strips ("Tora" (Salix schwerinii x S. viminalis)) are alternating with 48 m wide grassland strips. Yield and selected quality parameters of perennial grassland were assessed yearly from 2015 to 2017. The total amount of litter per square meter was also assessed yearly during the whole period of litterfall. The biomass yield of the willow short-rotation coppice was measured in 2016 as well as estimated yearly (2015 to 2017).
