During China's Warring States period, which consequence resulted when iron plows encountered heavily compacted soil?

💡 Explanation

Increased soil compaction raised resistance, causing increased shear stress concentration at plow defects, therefore the fracture probability increased rather than bacterial fixation, because bacterial nitrogen fixing requires loose soil rather than shear stress.
