This scientific paper will answer questions on the effects of salt on grass growth. In the winter, many people place a salt compound on their driveways to melt snow and ice that has accumulated. The following spring, it is noticed that the edges of the driveway does not have any grass growing and grass a little further from the driveway is growing slower than the rest of the lawn. It will be determined if grass growth is negatively impacted in the spring after a winter of salt compound applications.
Salt and Grass Growth
In the winter, salt is spread daily on the driveway in order to melt snow and ice. In the spring, when the grass begins to grow, it is noticed that there is not any grass growing about 3 inches from the driveway. In addition, the grass appears to be growing slower about 1 foot from the driveway. Prior to an experiment being conducted, it must be determined what the salt compound being applied to the driveway is made up of in order to get a clear picture of how it may be affecting the grass growth. Salt is sodium chloride that occurs naturally on earth as mineral halite. When mineral halite evaporates, it turns into salt lakes. The chemical compound is NaCl with 60.663% elemental chlorine (Cl) and 39.337% sodium (Na). Salt crystals are cubic in form and can be modified by temperature. Salt that is commonly used for deicing is rock salt also known as halite. Rock salt’s crystals are much larger than the common table salt’s crystals ("What is salt?," 2013).
Based on the giving facts and the chemical makeup of salt, it is believed that the salt compound used to melt the ice and snow is effecting the growth of the grass around the driveway and along the edges of the lawn.
Evidence obtained from the experiment, if the hypothesis is correct, will indicated that grassy areas nearest to the driveway that are exposed to salt does not grow and the grassy areas less exposed...
