When using bronze ploughs against clay-rich Mesopotamian soil, which risk prematurely limits efficiency?

💡 Explanation

Edge dulling significantly limited productivity because abrasive wear against siliceous soil particles exceeded bronze's hardness; therefore farmers needed frequent resharpening, rather than elastic yielding (too ductile) or shattering (insufficiently brittle), or corrosion (dry soil).
