Giessen long-term field experiment 'biological nitrogen fixation' - treatment plots

This data set describes the plot names and treatments of the Giessen long-term field experiment into biological nitrogen fixation. The treatment comprises a four-year crop rotation in which the first year is variable (fava bean, wheat or maize) crossed with various fertilization treatments (no fertilizer, PK fertilization or NPK fertilization). The experiment and data described in Hobley et al. 'Decoupling of subsoil carbon and nitrogen dynamics after long-term crop rotation and fertilization ', 2018, Agriculture, Ecosystems and Environment. https://doi.org/10.1016/j.agee.2018.06.021
