Site Soil

a.At my site the soil is sandy loam.

b.Because my site’s soil is sandy loam, it doesn’t retain as much water as loamy soil would, however, it holds more water than a sandy soil would. Water flows slower in sandy loam but slower than sandy soil in sandy loam.

c.In this area there are plenty of bushes, trees, grasses, lichen, insects, gophers, and earthworms (and probably some others).

d.The plants take nutrients from the soil through their roots, however animals like gophers and earthworms add nutrients back to the soil as fecal matter. Other organisms, like lichen, can also add nutrients (like Nitrogen) back to the soil when they fall to the ground from the trees.

e.Because there are plenty of plants holding the soil in place, erosion (especially quick erosion) isn’t likely. If there was a lot of heavy rain causing lots of run-off, it could erode. This would create steeper areas and crevices for water drainage that would lead to the pond. Erosion of the soil into the pond would make the pond larger, but more shallow.

f.It’s important to think about soil texture because it’s important for knowing the flow of water and the types of organisms present. For example, when we look at salt marsh soil you see clay soil that is low in oxygen and holds large amounts of water because the water cannot drain through. This means that the plants that survive there have specific adaptations for dealing with lots of water and low oxygen, you can’t just plant a poppy field there because they wouldn’t survive.
