Possible outcomes of amendment experiments. 1A = aerobic nitrification of 15NH4+; 1B = heterotrophic denitrification with 14NO3- and/or 15NO3-; 1C = OLAND with 15NH4+ or partial nitrate reduction to nitrite followed by anammox with 15NH4+ ; 1D = same as 1C except with standard nitrate; 1E = heterotrophic denitrification with standard nitrate; 1F = assimilation. 2A = aerobic nitrification of standard ammonium; 2B = heterotrophic denitrification with 14NO3- and/or 15NO3-; 2C = OLAND with standard ammonium or partial nitrate reduction to nitrite followed by anammox with standard ammonium; 2D = same as 2C except with 15NO3- ; 2E = heterotrophic denitrification of 15NO3-; 2F = assimilation.
