The composition of soil can be broken down to a mixture of both abiotic and biotic matter. This composition can include animal waste, minerals, water, and even air. The complex nature of soil can consequently be affected by a large number of factors. These factors may range from simple weather alterations to complex human alterations to environments that could easily impose effects on soil. To see the effects humans can have on soil, this experiment was conducted in which three counties with varying levels of human activity (measured in population) had samples of soil collected to be tested for varying levels of pH and nutrients. Correlation tests were conducted to capture any significant correlation between the different levels of human activity and the variables tested in the soil. The results of these tests suggested that there was no significant correlation between varying degrees of human activity and soil pH and nutrient levels.
