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.

There are 4 fundamental components of top soils regardless of the processes they are formed through. These are mineral particles, water, air, and organic matter. The mineral particles are in the form of sand, clay, and silt. Ordinarily, topsoil is made up of fifty percent spore spaces, which are filled with water and air in different proportions. The moisture content of the soil at a particular time determines its composition of water and air.

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.

The top soil does not extend too deep into the ground. In most cases, one will start accessing the subsoil after digging less than 30 centimeters into the ground. Subsoil is very different from top soil in many ways. In fact, soil can only be referred to as top soil if it meets certain classification criteria. Otherwise, it is classified 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 plants have their roots anchored in top soil. As such, it implies that global food production is highly dependent on the top soils, making it necessary to preserve it. Due to the shortage of appropriate top soil, there are commercial alternatives being produced as a result of advanced technology. These alternatives include peat, and they can be used for farming activities.
