                      (HCA) in the soil can promote microbial nitrogen (N)
                      immobilization. HCA incorporation is thought to reduce N
                      loss via nitrate (NO3−); however, it often increases
                      nitrous oxide (N2O) emissions in upland soils.AimsWe aimed
                      to investigate N2O emission and soil N retention in
                      different soils after co-application of mineral N
                      fertilizer, HCA, and phosphorus (P) fertilizer for
                      alleviating potential microbial P limitation.MethodsWe
                      conducted a 42-day incubation experiment with nutrient-rich
                      silty soil (RUS), nutrient-rich sandy soil (RSS), and
                      nutrient-poor silty soil (PUS). Soils were amended with
                      wheat straw, leonardite or sawdust, with 50 mg N kg–1 soil
                      dry weight (dw) and additionally with 0, 140, or 250 mg P
                      kg–1 soil dw.ResultsThe addition of 250 mg P kg–1
                      significantly increased CO2 emission by $88.6\%$ and
                      $19.8\%$ in wheat straw-amended PUS and RUS, respectively.
                      In the nutrient-rich soils, HCA co-applied with P mostly did
                      not reduce N2O emissions. In the sandy soil, sawdust and
                      leonardite with 140 mg P kg–1 significantly reduced the
                      cumulative N2O emissions by $76.3\%$ and $76.8\%,$
                      respectively. In the silty soils amended with wheat straw,
                      the retention of N in the form of microbial biomass and
                      ammonium in soil was paralleled by significantly lower
                      NO3− concentrations.ConclusionsWe conclude that P
                      co-application with HCA, such as wheat straw, might improve
                      N retention, even if N2O emissions did not decline. However,
                      we also found that different soils respond very differently
                      to combined HCA, N and P addition, which calls for further
                      research into the underlying mechanisms.},
