This finding was surprising as we expected neutral responses to time in the conventional fields, because conventional fields were never converted, and they were only plotted along the same time axis as the organic fields as controls,” say the authors. This suggests at least that changes in the microbiome may have driven changes in the enzyme activity in our fields.

The divergence between organic and conventional fields widened over time for enzymes in all cycles, and the Carbon-Nitrogen ratio/all C-related enzymes increased with time in organic fields.
