Generally, one of the last things that happens on any kind of construction job is that the topsoil is replaced. That's because the topsoil is usually removed in order to excavate or to allow the construction company to get at a particular part of the structure they are working on.
What Is Topsoil?
Topsoil is the first layer of what makes up the entire soil setup. That layer is generally between 2 and 8 inches deep. However, it can go deeper in areas like farms, mostly because more topsoil may have been added to existing soil to amend the soil so that it will grow better crops. The topsoil is also the layer in which most smaller plants, like grasses and flowers while larger plants like trees will usually have roots that go much deeper.
What Kinds of Topsoil Are There?
Topsoil breaks down into three basic types. Those are sandy, clay, and silty. Topsoil is broken down into one of these three categories by how much of a particular basic ingredient there is in it.
Clay: Clay soil is generally pretty fertile, but it does have a problem with retaining water. That means that roots can get waterlogged and some plants don't do well when their feet are all wet.
Sandy: Sandy soil doesn't have the same problem wth retaining water. Water filters through this soil pretty easily. The problem with that is that necessary nutrients can also wash right out of the soil along with that water. Sandy soil also has a problem with erosion because of the fact that water runs through it, wind can also pick up and blow this soil around easily.
Which Topsoil Is the Right Choice?
There is no one right answer to this question. The best choice of topsoil depends on the site. The goal is to match the existing soil as much as possible. One way to do that is to do a pH test. The soil's pH will tell you if it's alkaline or acidic. Testing the soil can be easy. One way is to send the soil out to a lab. The lab gives a very precise result, including the breakdown of the basic soil components. Another way is to do a quick onsite test. There are test kits that are sold in lawn and garden stores. They usually involve test strips that turn a different color depending on the soil's pH. These tests don't give exact results, but they do give a good basic idea of what the soil is.
Finishing up a construction job with putting topsoil back on the site means that the site can be landscaped and look completely finished. Contact a local company, such as Purdy Topsoil & Gravel, for further assistance.
