Salinization

Salinization:

In this experiment, there were seven bags; each was filled with a 120 mL salt solution, a paper towel, and five beans. The concentrations were as follows: 0, .5 1, 2, 3, 4, and 5 grams salt per 100 mL water.
The only bags that showed signs of germination were the control (0 grams) and the smallest concentration (.5 grams). The one that grew the best was the .5 gram concentration of salt. Based on this data, we can conclude that large amounts of salt (1 g per 100 mL or more) are not good for growing. We can also conclude that no salt can still work for growing, but a little bit of salt is the best. The .5g salt/100mL water solution was the equivalent to the amount of salt found in natural water such as rain (not acid rain) and fresh water.

Too much salt can cause problems such as toxicity, inadequate amounts of moisture and oxygen, and a high pH that makes necessary nutrients unavailable to plants. To remediate the soil, one can use deep tilling, breaking up larger pieces of soil to improve downward flow of water, soil flushing, using low-salt water to flush the root zone, chemical remediation, adding lime, sulfur, or calcium to the soil to replace the salt, and a combination of these methods which is the most effective.
