Topsoil or organic topsoil is known as the upper layer of a soil profile; this layer is usually darker in color (due to its excessive organic matter content) and more fertile than its counterpart (subsoil).
Topsoil is produced as a result of some natural biological and environmental processes. The depth of topsoil ranges from 5-20 cm (2-8 inches) deep and can be evaluated as the distance from the surface level to the subsoil. This layer is the strong base of most biological activity and because it consists of the highest concentration of microorganisms and organic matter, due to animal decomposition, plants, etc.
The primary elements of the topsoil composition are:
- Organic matter
- Mineral particles
The strength of the soil, including its bearing capacity, hinges on its skeletal form and reduces with the presence of organic matter. Water run-off leads to minerals from the topsoil layer moving down into the subsoil, which can result in some mineral shortage in the topsoil. This effect of this process is that roots have to go deeper to obtain nutrients. During construction, it is essential to remove the topsoil. Still, it should also be taking into consideration that by removing this layer, there will be an increase in the rate of erosion of soil minerals.
Construction activities can make organic matter present in the topsoil to compact and set in diverse ways, like roadbeds and foundations.

Use of Topsoil In Repairing Lawn Damage
Topsoil can be utilized to cover low areas of lawn to make the yard level, and it can also come in handing when top-dressing bare regions.

Ensure that the plant roots aren’t agitated while this process is going on, or discard the plant before the existing plants are revised and replanted later, or review the current soil before the plant are placed on the site.
Since including topsoil can also affect the pH level of the soil, adopt a soil test to determine if the pH of the soil needs adjustment or not before you plant grass or other plants.
Types of Topsoil
There exist three primary types of topsoil. They are as follows:
Sand consists of mineral particles and neatly separated rocks. Sand is a highly variable of topsoil and its hinges on the category of available local rock in the vicinity. There are two common types of sand; they are silica (which is normally made from quartz) and aragonite (which is formed from several years old life forms). Sand can be utilized for diverse purposes, like agricultural use, the building of bricks, glass, mortar, concrete, road, paint, etc.
This type of topsoil consists of uniformly concentrated levels of constituents such as silt, clay, and sand. The quantity of clay, silt, and sand can change, forming diverse types of loam-like clay loam, silty loam, and sandy clay loam. All these loam soils come with different ranges of characteristics, but the normal loam consists of more nutrients, moisture, and humus than sand. You can find loam in big fertile lands and is very good for farming. Loam can also be used for constructing walls of homes because it can regulate air humidity. This strategy is known as the oldest form of house construction.
The third and ultimate type of topsoil is the clay. This type of topsoil is formed and created from decomposed organic substances, normally wilted plants with a mix of powder rocks formed after several decades due to weather conditions. Also, because water can’t penetrate clay, it is usually utilized in the construction of dams, or it can be used as a hindrance to landfills.
