A Study on the Effects of Potash Tailings on the Growth of Barley and Flax |

Conclusions After examining my results, I found that my hypothesis was primarily correct. I discovered that potash tailings do have very harmful effects on plants, like delayed germination, decreased size, and they can even kill plants. As I had thought, the barley plants were affected less by the potash tailings than the flax plants. This project introduced some frightening new facts to our society. Farmers face many problems everyday, like drought, insects and disease, and this just adds one more to that very long list. There are now some questions we need to ask. What is really happening to all crops in Saskatchewan, and around Canada? Are they actually growing to their full potential? Saskatchewan produces a large amount of Canada's grain, and also the majority of Canada's potash. The mines leave their waste outside in large piles, making it very easy for it to spread. We must also look at the other problems this research introduced. It showed that it is not only the salt in the potash tailings killing the plants, but the other chemicals found in tailings. We need to wonder what would happen if it got into the groundwater supply? If these chemicals have such staggering effects on plants, what could they do to humans and other animals? This project revealed a new problem, and now that we know about it, we can look to see who, or what it is affecting and how we can help.
