The uppermost layer of soil is what is called topsoil. From the surface, this soil layer goes to a depth of between 5 and 10 inches. It contains a high concentration of microorganisms and organic matter. Topsoil is the layer of the earth where most biological activities take place. Materials such as air, organic matter, water, and mineral particles form part of this soil layer. When in search of topsoil Warren County NJ should be given priority.
There is so much variation in the quantity and composition of organic matter in the top soil from location to location. The strength of soil reduces with the increase in composition of organic matter. Normally, this reduces the bearing capacity of the soil. Different conditions determine the settling of organic matter and condensation. For example, settling of organic matter on roadbeds is totally different from settling in foundations. Normally, dewatering soils from these two sources affects their structure.
Top soils are needed for plants to grow. This is because plants obtain their nutrients from these soils in order to survive and grow healthy. Thus, most plants have their roots anchored in this soil. How deep the layer extends into the ground can be gauged by measuring the depth from the surface to the subsoil. Subsoil is usually more densely packed.
The term A Horizon or O Horizon is usually used in reference to topsoil, making it the topmost layer. Soil classification schemes used worldwide are British and US classification standards. There are certain conditions to be met for soil to be classified as top soil. These criteria usually consider factors such as carbon nitrogen ratio, particle size, nutrient content and extractable phytotoxic elements.
Factors such as electrical conductivity, pH, distribution, organic matter content, physical and chemical contamination and loss on ignition are also considered when classifying soil. The process of extracting soil for testing is done following certain standards. If an area needs to be used for construction, it has to be underlain by certified subsoil before construction is started
When starting farming or gardening project, it is mandatory to assess the soil to ensure that it has satisfactory properties. The nutrient composition of the soil should match to the requirements of the specific plant to be grown. Most plants require specific soil conditions. If the desirable conditions are not met, the soil can be altered by altering the quantity of various elements.
Nitrogen and carbon are the two major components in the top soil that enable plants to grow healthy. Tissues in plants are developed by nitrogen. In order for plants to develop, they require energy too and this energy is generated by carbon. These elements should be available in different ratios for the plants to grow well. The suitable ratio should fall below 20 to 1. This is according to standards established in the US.
One can buy topsoil commercially to improve the fertility of their lawns and gardens. The soils is sold in various mixture so that they are suitable for different applications. Examples include peat, potting soil, and container gardens. These products can be bought from garden stores around the US.
