      abstract     = {Biogas digestate (BD) contains nitrogen (N), phosphorus
                      (P), and potassium (K) and is easily and largely available
                      in Germany and other countries in Europe. Nevertheless, few
                      studies compare BD to mineral NPK fertilizer, particularly
                      under soil compaction. The characteristics of these
                      fertilizers and soil compaction may affect rhizosphere pH
                      and root development, thereby affecting nutrient uptake by
                      plants. This 18-day rhizobox study evaluated initial maize
                      growth and root architecture responses to BD (derived from
                      maize silage+chicken manure), mineral NPK, and BD + NPK
                      fertilization under compacted (0–25 cm compacted; 25–55
                      cm loose) and loose (0–55 cm) substrates. Treatments
                      promoted similar shoot biomass, specific leaf area, and
                      sufficient shoot N, P, and K nutrition. Shoot P content in
                      BD + NPK and NPK was $29–33\%$ higher compared to BD. Root
                      P content in NPK was $26\%$ higher than in BD, independent
                      of compaction, likely favoring root proliferation and
                      explaining the higher root:shoot ratio in NPK. In loose
                      soil, the main root length in NPK was $49\%$ higher compared
                      to BD, but rooting was deeper in BD. Rhizosphere
                      alkalinization measured non-invasively suggested
                      preferential maize N absorption as nitrate. Combining BD
                      with fast-soluble P sources may provide maize performance
                      comparable to mineral NPK.},
