BonaRes SIGNAL, Site: Reiffenhausen, biomass production 2016/2017

This data was collected in cropland agroforestry (=alley cropping of poplar clone max 1 with summer barley) at Reiffenhausen/Germany during 2016/2017. Data was taken at 4 replicates each in the tree strip component of agroforestry, the cropland of component of agroforestry at different distances from the tree strip (=1m, 4m, 7m) and at the monoculture. We measured productivity as dry mass of harvested (plot combine) corn and straw as well as above-ground biomass production of trees (calculated with allometric equations of the form dry mass = a x dbh^b and adjusted to a subsample of 25 harvested trees within the observed dbh range) plus leaf litter in the tree strip (taken from one litter trap per replicate).
