The Study of Soil Quality in Macomb County

The purpose of our experiment was to discover the quality of the soil and therefore the plant's ecosystem within Macomb County. By classifying and testing soil specifically for pH, nitrogen, phosphorus, and potassium we, with some amount of accuracy determined the soil quality of southeastern Michigan to be, for the most part, uniform throughout. On average our results indicated that we tested fairly neutral soil. Our nitrogen levels reported los results due in part to the season, but were actually large in the big picture. Nitrogen is used to make the chlorophyll in plants and because the plants are entering a dormant stage they do not require the nitrogen in the soil. Phosphorus and potassium both gave us results that reported either medium or high. Potassium is used by plants to help make the stem strong which explains why there should be high results. Phosphorus gave us the most variance within the tests. We hypothesized that this is because plants use phosphorus for root development and growth and some may still be completing this process.
