Which limiting factor constrained large-scale chinampa cultivation surrounding Tenochtitlan?

💡 Explanation

When organic matter accumulated in chinampas, decomposition rates limited land restoration, since the microbial activity breaking down plant waste required suitable temperature and moisture, slowing soil creation. Therefore the decomposition rate becomes a limiting factor, rather than flooding, labor, or nutrient depletion, which could be more readily managed through existing technology.
