The outermost layer of soil is referred to as topsoil. The layer extends from 5 and 10 inches into the ground from the surface. This layer has the largest concentration of organic matter and microorganism. Also, it is in this part that most biological activities on earth happen. Soil in this layer is composed of numerous materials such as organic matter, air, mineral particles and water. When one needs topsoil Warren County NJ offers the perfect location to visit.
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 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.
In top soil, nitrogen and carbon are the most important elements for healthy growth of plants. Carbon usually provides the needed energy for plant development while nitrogen is vital for tissue building. In order for plants to grow well, they require the two elements in varying proportions. The most suitable ratio in the US is 20 to 1.
One can purchase top soil in order to improve the fertility of their gardens and lawns. These soils are usually sold in numerous mixtures so as to be suitable for different farming applications. Container gardens, potting, and peat are among the commonest applications. In the US, they can be bought from garden stores.
