Which environmental effect resulted in pre-Columbian chinampa systems if drought increased evaporation concentrating dissolved salts?

💡 Explanation

When drought increased evaporation and limited rainwater flushing, salt concentration in chinampa soils increased because capillary action drew up subsurface minerals, negatively affecting the nutrient availability of maize. Therefore, reduced nutrient solubility resulted, rather than altering pest resistance, enhancing microbes or accelerating growth, because those depend on separate mechanisms.
