← HistoryWhich consequence results when irrigating ancient chinampas with excessive dissolved salts during long dry spells for maize cultivation?
A)Increased nitrogen fixing bacteria efficiency
B)Accelerated anaerobic decomposition processes
C)Osmotic stress inhibiting root uptake✓
D)Decreased soil particle aggregation stability
💡 Explanation
Excessive salts increase the soil's osmotic potential, thereby causing osmotic stress that inhibits the roots' ability to absorb water; because of reduced turgor pressure, wilting and stunted growth would occur, therefore maize hydration suffers, rather than benefits from enriched nitrogen.
