It takes a very long time for soil to form. A number of processes are involved in soil formation. Weathering of the underlying rocks is one of these processes. Another process is where plant materials decompose. When materials get deposited in rivers and seas, a type of soil known as alluvial soil is formed. On the other hand, the action of wind leads to formation of loess soils. Topsoil is the soil found on the outermost layer of the earth. When in search of Topsoil Grand Blanc MI should be given priority.
Regardless of the manner in which topsoil is formed, there are four basic components that make it, that is, air, water, organic matter, and mineral particles. Mineral particles exist in the form of clay, silt, and sand. Typical topsoil contains fifty percent of spore spaces that are filled with air and water to varying levels. The composition of air and water will depend on the moisture content of the soil at the moment.
The remaining fifty percent consists of mineral particles and organic matters. Organic matter makes about 2 to 6 percent of the weight of typical mineral soils. In organic soils such as peats, organic matter makes about 30 to 100 percent of its weight. A country can have a wide range of different types of top soil. The composition and qualities of these soils vary widely from one place to another.
Even small farms can have various types of soils. This is contributed to by a number of factors such as the process of soil formation that occurred there. Farming and other activities which happen in the location also determine soil characteristics. The climate, farm management, vegetation, type of parent material, time, and topography are the biggest determinants of soils found in a certain area.
Top soil only covers a small depth into the ground. The layer mostly occurs to a depth of less than 30 centimeters where the subsoil layer begins. There are great differences between top soil and subsoil. For soil to be classified as top soil, it has to meet certain requirements. If it fails to meet the conditions, then it is placed under subsoil.
One major characterizing feature of topsoil is the fact that it has a darker color than subsoil. The darker color is brought about by the presence of organic matter that results from decaying plants and plant roots. Even decaying animal tissues contribute to the dark color. The presence of organic matter in the soil makes the top soil more fertile in comparison to subsoil.dd
Manure, fertilizer, compost and other additives added to the top soil also contribute to its fertility. The layer is also looser and less compacted due to presence of organic matter. This makes it to have less bearing strength. The layer is also looser than subsoil because of human activities such as plowing.
Most crops and plants have their roots growing in the top soil layer. That means that global food production is heavily dependent on these soils, making its preservation very important. The shortage of suitable top soil has led to the invention of commercial top soil that can be bought from garden stores for farming activities.
