Generally speaking, there are three types of topsoil available such as natural topsoil, skip waste soil, and blended soils. Natural topsoil is extremely variable in quality and availability and ranges from an acidic, nutrient-deficient sand, to a strongly alkaline silt-loam, and to organic-rich peaty clay. If the characteristics of the topsoil are not suitable for the plants grown in the soil, then the plants can fail to grow, and this can be very expensive. Natural topsoil always contains a bank of seeds, such as annual and perennial weed seeds; and may frequently comprise rhizomes of persistent weeds and grasses, such as creeping buttercup, and couch grass. This topsoil is derived from former agricultural land and may contain elevated levels of heavy metals because of the repeated application of sewage sludge, etc.. This is important if the topsoil is used for sensitive plants like domestic gardens. Skip Waste Soils are more prevalent in urban areas and are a consequence of the materials derived from building and demolition operations, which are then screened.

Skip waste lands are a mixture of topsoil, subsoil, clay and include numerous fragments of construction waste materials such as concrete, brick, mortar, ash, clinker and to lesser extent asbestos, glass, metal, plastic and wood. Skip waste soil is usually extremely alkaline with a pH range of 8 - 10, saline, deficient in organic matter and plant nutrients, and can often have elevated levels of zootoxic and phytotoxic contaminants. Although skip waste dirt can look like good topsoil, it often results in failure in the growth of the plants or, stunted growth. In addition to this, the consequences of using skip waste dirt include possibly having contaminants present in a backyard. Blended Soils result when two or more parts are intimately blended to form a growing medium. Composting is a excellent start. By turning organic materials into compost, you are using a wide variety of substances and so putting back a great array of minerals and nutrients. Compost provides humus in the soil, which improves the soil structure and the moisture holding capacity of the soil. Add compost as a 5 to 10cm layer of mulch to the surface of your soil. Don’t dig your soil.
It’s not required to turn over, or twice dig your soil, and it can destroy the soil texture and the micro-organisms which are of great advantage to your soil. Besides, you don’t need to dig. Let your earthworms do the bulk of the job. They take nutrients from the surface and work their way deep into the soil, making tunnels as they go, which enables both air and water to penetrate deeply. This is a superb benefit - so allow the worms work the soil for you. These elements can be prime organic topsails recycled by the food production industry, and also recycled, peat-free, soil conditioner. These soils are blended from raw materials to ensure consistent quality-soil is produced, with no variation in consistency. It is necessary to account for the full tractability of all the elements of a mixed soil and to have them analysed for PTE’s regularly. Ideally, landscaping topsoil is organic-rich topsoil, with a ph ranging from slightly acidic to slightly alkaline, and is a fertile sandy loam, free of contamination with no waste or sharp materials. Ideally, this would be available all year round in bulk or bags.
