Which consequence results from excessive soil salinity in Aztec chinampa agricultural systems relying on maize cultivation?

💡 Explanation

When soil salinity increases excessively, osmotic pressure diminishes water potential gradient between soil and maize roots, impeding water and nutrient uptake because ions attract water from root membrane. Therefore nutrient uptake is reduced, rather than increased disease, leaching, or photosynthesis which require different soil condition shifts.
