Loamy Soil

The soil at my site is loamy. I think because there are a lot of trees at my site that having sand that is more clay-like than sandy helps by grounding the roots so that the trees don’t fall over. Because the trees are on a slope, water needs to be able to be absorbed quickly, which is why it would be good to have sandy soil instead of clay so that the water doesn’t just flow past and down to the bottom of the hill. I think trees, especially large ones like the eucalyptus affect the soil by giving the soil more nutrients, and roots so large that it separates the soil. Also a lot of birds are in the area which can aid in seed dispersal. I don’t think the soil I collected will erode, when I squeezed the soil it stuck together for a bit and then broke up once I hit it into my other hand, but only if I threw it pretty hard. I think this would be helpful to avoid erosion because when the soil gets a little wet, which happens a lot here in SF, then it packs down tight enough that it doesn’t break-up easily. I think it is important to think about soil texture because based off of what the soil is like you can predict what could happen to that area in the future.
