Which consequence resulted from intensive maize cultivation during the Mayan Classic Period collapse?

💡 Explanation

When intensive maize cultivation increased, subsequent soil depletion of nutrients forced reliance on monoculture planting, leading to increased vulnerability to soil pathogen virulence because there was no crop rotation to disrupt pathogen life cycles. Therefore, increased pathogen virulence results, rather than changes in aquifers, methane, weathering, each require different soil ecological mechanisms.
