← HistoryWithin Aztec chinampa agriculture, which consequence followed when poorly decomposed organic matter was added near maize roots?
A)Denitrification exceeds nitrogen fixation✓
B)Oxidation stress damages plant tissues
C)Methane production affects root respiration
D)Acidity hinders nutrient ion uptake
💡 Explanation
Denitrification exceeds fixation because anaerobic decomposition produces excessive nitrite; inhibiting nitrogen uptake, harming maize yields. This outcome arises from nutrient cycling imbalances, therefore impairing root health rather than direct toxicity.
