Which risk increases when long-fallow crop rotation on pre-Columbian chinampa (raised bed) agriculture lacks consistent organic replenishment?

💡 Explanation

Nutrient depletion intensifies because the mechanism of nutrient cycling via decomposition of added organic matter is reduced. The soil's natural reserves are steadily removed and none are put back; therefore, the problem magnifies rather than stabilizes, and the plants effectively starve.
