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.
The composition of organic matter in topsoil varies a lot in quantity from one place to another. Naturally, the more organic matter is comprised in soil, the less strong it becomes. This reduces its bearing capacity. The condensation and settling of organic matter occur differently under different conditions. For instance, the way organic matter settles in foundations is not the same to the way it happens in roadbeds. Dewatering such soils affects their structure.
Top soil is vital for plant growth. This is due to the fact that plants get nutrients for growth and development from these soils. As such, most plants are anchored in top soil. The depth to which the soil extends into the ground is measured from the surface to the subsoil. The subsoil is normally more densely compacted.
The phrases A Horizon or O Horizon are used to refer to topsoil in soil classification. This makes it the topmost layer. Some of the available classification schemes used in the world are the US and British classification standards. The soil must meet certain threshold criteria for it to be classified as top soil. The criteria consider factors such as particle size, extractable phytotoxic elements, nutrient content, and carbon nitrogen ratio.
Additional factors that are considered under most criteria include loss on ignition, Ph, chemical contamination, distribution, electrical conductivity, and organic matter content. There are set standards to follow in the extraction process too. In the event that the land is being prepared for a housing project, it is required that the top soil is underlain with a layer of certified subsoil. Afterwards, there should be proper compaction prior to construction.
Soil must also be assessed properly to determine if it has the required characteristics before starting a farming or gardening project. It should have the nutrients required by plants for good productivity. Soil conditions required by different plants vary. Certain elements of the soil can be altered if the soil does not meet the needed nutrient composition for a certain type of plant.
The two most vital parameters to healthy growth of plants in top soil are carbon and nitrogen. Nitrogen serves as a tissue builder while carbon provides the necessary energy required for development in plants. Plants require these two elements in different ratios for suitable growth. A ratio of less than 20 to 1 is deemed suitable according to standards observed in the US.
Fertility of land can be upgraded by adding commercial top soil. Since different applications require soils with different nutrient compositions, different mixtures of topsoil are available in the market. Container gardens, peat, and potting soil are the commonest products available. A purchase can be made easily from any garden stores in the US.
