The relationships between changes in OC and N stocks in total soils and changes in OC and N stocks in aggregate size classes.
<p>The units for the changes in OC and N stocks in both total soils and aggregates are kg m<sup>-2</sup>.</p
The effects of cropping systems on OC and N stocks and C/N ratios in aggregate size classes at the 0–20 and 20–40 cm depths.
