Soils

In my park there was a lot of sandy soil and top soil. The park had a majority of sandy soil even in the woods because it is so close to a beach. There was leaves everywhere in the park still, covering up some pretty good top soil. The trees grew in this sandy soil, but their roots were much farther down so they could absorb water constantly from better soil. This is because sand does not retain water very well and is not very good for growing plants.

Also in my park there was some highly organic top soil. This soil was in the field where the grass grew as well as the soil some flowers were growing in. This top soil is nutrient and very good for growing the grass in. It supplies sturdiness so the rain does not wash the grass away in a storm and the top soil since it is only a couple of inches supplies the small grass roots with nutrients. 







Soil is made up of a lot of organic compounds, but these compounds don't break down themselves. This compounds are usually dead plants or dead organisms and are broken down by other organisms eating and digesting the food. One example is a grub. This grub will eat a dead tree and its feces go into the dirt and make it more rich. This method applies to any living thing that eats and digests organic matter. In my park is was grubs, worms, slugs, and even a snake.







Over all my park had a lot of sandy and some high organic top soil. It takes a long time for top soil to form and it is from the break down of organic material. This material is broken down by things ingesting and then digesting the material. Soil type is important because some plants require a unique blend of soils.
