Observation: During the winter, you spread salt daily on your driveway to melt the snow. In the springtime, when the lawn begins to grow, you notice that there is no grass growing for about 3 inches from the driveway. Furthermore, the grass seems to be growing more slowly up to about 1 foot from the driveway.
Question: Might grass growth be inhibited by salt?
Winter times are the tough times every year in a since because you have to do so much to keep your yard healthy and safe. It’s when you shovel the snow, pave the driveway, and place salt down so that the ice doesn’t freeze up on your driveway and make it unsafe. Was wondering what happens to the grass around the driveway that gets salt on it. Considering you put the salt down just about every day until the weather becomes warmer. In my observation I noticed that the grass wasn’t growing right when the springtime comes back. With a little research I found that the salt raises the solute level of the soil around the plant root, since plants roots sometimes absorb water by raising the mineral level within the endodermis layer, actively, the amount of salt outside the root prevents water from entering the high solute level within the root. As well as possibly “sucking” water out of the cortex. There saying in simple terms plants need water to grown and get its nutrition from. With the salt having been put on every day for the amount of time it was winter it just collected and by time the springtime came around the water was unable to get to the root of the grass. With water not getting to the roots to help them grow they don’t grow or take longer to grow. Hypothesis is what would happen if there was a way to put a border protection for the grass so the salt doesn’t affect the grass. Prediction that there is so kind of salt that helps keep the ice gone and dissolves before springtime so it doesn’t affect the grass growing. I will try to find 3 different types of salt that prevents ice and is healthier for the grass. Went to a hardware store found three different salts products that seemed to work for the experiment. Was able to get sample packs, because that was all was needed. I also got the hardware store samples of grass to use as the grass in my experiment. Next I make an area where I would do the experiment. It had a small area of concrete where I would put the ice and so grass on the side of it. I did each salt one at a time with a few days between each one. I would put the salt on with ice water froze on the concrete and place salt on the ice and grass and put it in a safe area in the freezer. As each salt was put on I took a picture of before and after. As each came out the freezer I would let it sit outside for a few days with watering the grass and put what you would normally put on the grass to help it grow. I also took pictures of before and after during this process. Once that was done I recorded what the outcome was and what happened each day between the samples going in the freezer to being outside growing. As a result the salt product two was the most affective product. It didn’t completely hurt the grass, but the grass grow slow but not as slow as with regular salt.
In conclusion in all the experiment was a success in most ways I would say. The thing is salt is salt no matter what kind you get you really can’t change it too much, because if you do that than it wouldn’t be salt. I was able to find the best result to at least help grass during the winter instead of hurting it. It is really a hard thing because without the salt your home would be in danger, whereas with the salt your grass is in danger. I think that my experiment was a success, because I was able to find the best outcome to help both parties without changing any of the products. Meaning I was able to find a safer, lighter salt that didn’t harm the grass as bad but still did the job you needed it to do which was prevent ice from forming on your driveway.
