There are various processes of soil formation which happen over a long period of time. One of the processes involves the decay of plant matter while the other involves weathering of underlying rocks. Alluvial soils are usually formed by the deposition of sediments on the beds of seas and rivers. On the other hand, loess soils are formed by wind action. Soil which is found on the topmost surface is referred to as topsoil. When one needs Topsoil Grand Blanc MI offers the perfect location to visit.
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 other half usually consists of organic matter and other mineral particles. There is about 2 to 6 percent composition of organic matter in mineral soils. Organic soils such as peats on the other hand have composition of organic matter of around 30 to 60 percent of their total weight. A country usually has wide range of top soils. Normally, their quality and composition is different from one location to the other.
Funny enough, even a small farm might have multiple types of soils within it. This is influenced by several factors, including the soil formation process that occurred in that place. Farming and other activities that go on in that location may also influence the characteristics of the soil. The major determinants of the type of soil found in a location include climate, type of parent material, vegetation, topography, time, and farm management.
The depth to which top soil reaches into the ground is not that much. Mostly, its depth is limited to about 30 centimeters. There are numerous differences between top soil and subsoil. As a matter of fact, there is a criterion to be met for soil to be considered as top soil. Else, it will be categorized as subsoil.
One difference top soil and subsoil have is that top soil is darker in color. Organic matter in this layer gives it the darker color. Organic matter is formed as plants and plant roots decompose. It also results from decaying animal tissues. Fertility in top soil is greatly influenced by organic matter. This also differentiates it from subsoil.
Fertility of top soils is enhanced by the fact that top soils have a lot of manure, fertilizer, compost and other additives which are added to them. Also, due to the presence of organic matter, top soils are looser and less compacted. As a result, its load bearing capacity is lower. Other factors contributing to looseness of top soils it the constant ploughing and other human activities.
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.
