← HistoryWhich outcome occurred with early Chinese cast iron agricultural tools placed in acidic paddy fields?
A)Reduced friction against the soil
B)Increased rate of phosphorous uptake
C)Decreased microbial activity period
D)Accelerated process of iron corrosion✓
💡 Explanation
Early cast iron plows experienced accelerated corrosion because galvanic corrosion occurred between areas within the iron's microstructure that had varying carbon content. This resulted in early tool failure, therefore accelerated corrosion rather than any intended benefit influenced farming practices.
