I think it does. I learned in geography that in the Savanna, when water evaporates from the ground, salt from the evaporated water is left on the surface, which harms the plants around it.
I hope that helps!

What happens when you mix water and salt and leave it for a week?
If you mix water and salt and leave it for a week, the water will evaporate but the salt will remain. As the water evaporates, the salt crystals will gradually become more concentrated. Eventually, you will be left with a solid mass of salt crystals.
How do you crush a rock salt?
The large rock salt crystals can be cleaned with a small stream or light spray of luke warm water. As the water passes over the salt, brush off the dirt and then place on a towl to dry. Spray a clear coating over the dry salt to keep it from dissolving and preventing damage.
Where in nature can you find crystals?
The longer a molten material has to cool, the greater its crýstals may grow. Water frost grows in still weather. Frozen lava grows into spar and ore by ancient volcanos. Salt grows on seashores and in caves.
How do you separate salt from the solution?
It is possible to remove salt (chemical name, sodium chloride) from aqueous solution by the evaporation of the water. The water will boil, turning to a gas, and leave behind a dry salt residue. This can be done in the following experiment: Apparatus - Salt solution Tripod Heat (bunsen burner) Boiling dish Method - Pour the salt solution into the boiling dish. Place this dish on the tripod with the heat underneath it. Carefully apply the heat, and keep an eye on the experiment. The water will start to boil, and evaporate away. Once the water has completely evaporated, remove the heat. You are left with salt crystals in the dish.
What are examples of molecular substances?
Salt, Snow, Ruby Crystals, Gypsum Crystals, and Fluorite Crystals.

How do you separate a mixture of water and salt?
Evaporate off the water leaving the dry salt crystals behind.
How does salt water evaporate?
The water in the salt water evaporates, leaving a dry residue of salt crystals.
Are the crystals of salt really dry?
no
Does salt absorb food coloring?
Yes. But this occurs because salt is soluble in water, in which the coloring is dissolved. The color is retained by the salt crystals when they dry.

If you made a mixture of iron fillings and salt how could you separate that mixture into its 2 original substances?
Place the mixture in water. You recover the iron once the salt dissolves. Then allow the water salt mixture to dry and allow salt crystals to reform.
How does deicer dry up an earthworms?
De-icer is made of calcium chloride or other chemical like it mixed into water. Some are simply salt crystals or glycol. All lower the freezing temperature of water. If an earthworm is placed into it, the water that is in the worm will leave and try to equalize the water in the worm with the water outside the worm. That will not work and so the worm is "sucked" dry of water.
How can you show salt water is a mixture not a compound?
Evaporate the water from the salt water to leave the salt. Get fresh water once it is dry and add it to the salt. The salt dissolves again. A compound cannot be separated by simple means (e.g. Evaporating). A mixture can be.
Can salt water be used for cement mixtures?
Generally, salt is harmful to concrete. It will seriously corrode any reinforcing steel. The salt crystals, when the concrete is dry, will weaken the concrete. The setting of cement is a complex set of chemicals, calcium sulphates and silicates mainly. The presence of salt may interfere with these crystals forming, which may take years.
Where in nature can you find crystals?
The longer a molten material has to cool, the greater its crýstals may grow. Water frost grows in still weather. Frozen lava grows into spar and ore by ancient volcanos. Salt grows on seashores and in caves.
How do you separate salt and sand from water?
Fist filter off or sink off the sand from water with dissolved salt. Then evaporate the water (by boiling off) from the solution, leavinfg the dry solid salt crystals.
