← HistoryWhich agricultural outcome resulted from slash-and-burn practices used to cultivate maize during the early Mayan civilization?
A)Increased long-term soil fertility
B)Reduced vulnerability to crop disease
C)Temporary boost in yields before decline✓
D)Improved water retention in karst soils
💡 Explanation
When forests were cleared via slash-and-burn, nutrient release occurs through ash deposition, enhancing the soil in the short term because of its readily available minerals, but this quickly depletes without replenishment. Therefore a temporary yield boost resulted before rapid decline, rather than long-term fertility, disease resistance, or water retention which require sustained soil management practices.
