Explain what happens when NaCl and other salts build up in soils?
What will be an ideal response?
The buildup of salts decreases soil water potential. Reducing soil water potential can lead to plant
wilting because the movement of water from the soil into the roots and up to the leaves depends on a
water potential gradient. When soil water potential is at the wilting point, leaves will wilt.
