In this project we were collecting soil samples around the Lincoln Park area. We were testing the chemistry of these samples in order to be informed on how the soil feedback helps the vegetation in certain areas. The factors that we were testing for were nitrogen, phosphorus, potassium and pH levels in the soil. Looking at our data we concluded that the richest soil in the area was loam because the vegetation was mostly herbaceous. When we looked at  all of the soil types we found out that pH was very similar because all the levels ranged from a 7-8 pH. The fact that the soil is alkaline told us that the soil is not very acidic so therefore soil bacteria is able to give enough nutrients to the plants and grass. Sandy loam and sand had the highest nitrogen levels compared to the other soils. We decided to look at the percentage of vegetation for both of these soil, we figured that the percentage of grass, no vegetation and herbaceous plants were very similar to each other with only  a 5-10 percent of difference from each vegetation. The vegetation in both of these were balanced out. The lack of nitrogen worried us in the rest of the soils because nitrogen is in involved in the process of photosynthesis, making the plant have its green color pigment. Phosphorus levels were very low in silt and clay loam meaning that the plants in the area are not receiving enough water to have strong roots. We looked at the percentage of vegetation for these two soils and compared them,we discovered that both these soils had a high percentage of grass. Some uncertainties that exist in this project is the fact that we found very little soil samples of certain textures of soil which effects the data because of our sample size. We learned how ecological factors such as soil can affect plant growth and health. Lastly we learned how fertilizers can affect the nutrients in a plant. Our hypothesis was correct because when testing the chemistry and texture of the soil we were able to conclude the plant health and amount of vegetation in the Lincoln Park area with these samples.
