During the past decade, climate change has become an important topic. A few ramifications include an excess amount of carbon dioxide and rising temperatures. It is predicted that ecosystems may change due to climate change and its effects on soil communities, resulting in a decrease in plant biodiversity. Soil communities contain tons of components with minerals being one. For this study, different treatments were formed, each containing varying levels of nitrogen, phosphorus, sulfur, and lime and altering the pH. I sowed three different species: Cosmos seeds, Myosotis Forget-Me-Not seeds, and Cruciferae Brassica nigra Mustard seeds. I hypothesize that as the treatment levels decrease in pH the sprouting time and plant growth will increase. Additionally, I predict that as the treatments increase pH, sprouting time and plant growth will increase as well. The results did not support my hypothesis. Only two pots have sprouts. The ANOVA results for the sprouting time in response to the treatment types was 0.042, a rejection of the null hypothesis. Moreover, the ANOVA p-value for the treatment type effect on plant height was 0.000024....
