← HistoryWhich 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.
