Broadly speaking, there are three types of topsoil available such as natural topsoil, skip waste dirt, and blended soils. Natural topsoil is highly variable in quality and accessibility 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 aren’t acceptable for the plants grown in the soil, then the plants can fail to grow, and this can be quite expensive. Natural topsoil always contains a bank of seeds, such as perennial and annual weed seeds; and can frequently comprise rhizomes of persistent weeds and grasses, such as creeping buttercup, and couch grass. This topsoil is derived from former agricultural land and might contain elevated levels of heavy metals as a result 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 common in urban areas and are a consequence of the substances derived from building and demolition operations, which are then screened. Skip waste soils are a mixture of topsoil, subsoil, clay and contain numerous fragments of construction waste materials such as concrete, brick, mortar, ash, clinker and to lesser extent asbestos, glass, metal, wood and plastic.

Skip waste soil is usually extremely alkaline with a pH range of 8 – 10, saline, deficient in organic matter and plant nutrients, and may often have elevated levels of zoo-toxic and phototropic contamination. Although skip waste soil can seem like good topsoil, it often results in either failure in the growth of the plants or, stunted growth. In addition to this, the consequences of using skip waste soil include possibly having contaminants present in a backyard. Blended Soils result when two or more components are intimately mixed to form a developing medium. Composting is a excellent start. By turning organic materials into compost, you are using a wide variety of materials and so putting back a excellent range of nutrients and minerals. 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 the soil.
Do not dig over your soil. It’s not necessary to turn over, or twice dig your dirt, and it may destroy the soil texture and the micro-organisms that are of great advantage to your soil. In any case, you do not need to dig. Let your earthworms do the bulk of the work. 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 great benefit – so let the worms work the soil for you. These components can be prime organic topsails recycled from the food production industry, and also recycled, peat-free, soil conditioner. These soils are mixed 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 components of a blended 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 sharp or waste materials. Ideally, this would be available all year round in bulk or bags.
