Which agricultural consequence results when chinampa fertility decreases?

💡 Explanation

Declining fertility decreases populations of soil microbes; therefore, ammonium oxidizing bacteria, crucial for completing nitrification, become scarce. This hinders nitrate mineralization efficacy because without sufficient nitrification, nitrogen remains in less usable forms rather than readily usable nitrates.
