Which risk increased significantly when early Mesopotamian bronze-tipped plows encountered saline soils?

💡 Explanation

When saline soils contact bronze tips on plows, galvanic corrosion accelerates because the salt solution acts as an electrolyte between different metals in the bronze, preferentially corroding the more active metal component. Therefore, increased corrosion results, rather than reduced aeration, increased force, or embrittlement, which depend on other mechanisms like compaction or specific alloy composition and heat treatment.
