Results of ANOVA of soil N transformation rates for the factor treatment in control (NPK) and biochar (BC3N) treatments.

All transformation rates were measured and analyzed by one-way ANOVA for July 2011 data (“one date”). Nitrification and nitrate consumption was measured three times for NPK and BC3N treatments (“three dates”) and analyzed by two-way mixed ANOVA. Abbreviations: GP, gross production (influx); GC, gross consumption (efflux); Prot, protein; AA, amino acid; N min, N mineralization; NH4+, ammonium; NO3−, nitrate.
