Interestingly, root N concentration (RNC) and nodule N concentration (NNC) exhibited a highly significant negative correlation ( p < 0.001) during both the V9 and R5 periods ( Figure 8 c,d). 3.

Regarding specific root length, it exhibited an increasing trend with lower sulfur concentrations and a decreasing trend with higher sulfur concentrations ( Figure 2 c,d), indicating that lower sulfur concentrations promoted the growth of fine roots, while higher sulfur concentrations inhibited their growth.
