In pre-Columbian chinampa agriculture, which effect resulted from the anaerobic decomposition of organic matter?

💡 Explanation

When organic matter decomposes anaerobically in chinampas, ammonification occurs because heterotrophic bacteria break down organic nitrogen compounds into ammonia, enriching the soil. Therefore ammonia enhances soil fertility in the plots supporting continuous maize cultivation, rather than increasing salinity, emitting inhibitory methane, or depleting nitrogen.
