History

Which consequence results when intensive chinampa cultivation reduces topsoil's salinity?

A)Increased alkalinity and trace mineral availability
B)Decreased osmotic stress on crop roots
C)Accelerated rate of nitrogen fixation
D)Reduced susceptibility to temperature fluctuations

💡 Explanation

Decreased salinity allows osmosis favoring root water uptake; therefore, osmotic stress is reduced because more water moves into the plant due to the LOWER solute concentration, rather than water being drawn out by concentrated salts.
