Soil Components Essay
The purpose of this lab is to separate soil by setting in water to find the % of various components. In this lab I learned a lot. I learned that there is a lot more stuff to the soil than we can see; there is floating leaf litter, Sunken leaf litter, silt and sand all in a jar of soil. However, it takes time to sort itself out and that is why we left it alone for a week so it could separate out into all the different layers. The composition of the soil could effect organisms in the quadrat for many reasons. The composition effects the nutrients. Plants require a certain amount of nutrients to produce what they need to. The nutrients come from the decomposed soil so it has to be the right amount of decomposition that takes place.
We have mostly granite rocks in this area and soil derived from granite this effects us and plants in a big way. Granite rocks cause acid rain because of the chemicals that they that they give off into the air. A plant requires a pH of 6.8-7.0. The acid rain will change the pH so that it
