Broadly speaking, there are three kinds of topsoil available such as natural topsoil, skip waste dirt, and mixed soils. Natural topsoil is highly 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 aren’t suitable for the plants grown in the soil, then the plants may fail to grow, and this can be quite expensive. Natural topsoil always comprises a bank of seeds, such as annual and perennial weed seeds; and can frequently contain rhizomes of persistent weeds and grasses, like creeping buttercup, and couch grass. This topsoil is derived from former agricultural land and might 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 crops such as 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 soils are a mixture of topsoil, subsoil, clay and contain numerous fragments of construction waste materials such as brick, concrete, 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 can often have elevated levels of zootoxic and phytotoxic contaminants. Although skip waste dirt can seem like good topsoil, it often results in failure in the growing of the plants or, stunted growth. Along with 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 mixed to form a developing medium. Composting is a great start. By turning organic materials into compost, you are using a huge array of materials and so putting back a great array 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 your soil.
Do not dig over your soil. It is not required to turn over, or double dig your soil, and it can destroy the soil texture and the micro-organisms which are of great benefit to your soil. Besides, you do not need to dig. Let your earthworms do the majority of the job. They take nutrients from the surface and work their way deep into the ground, making tunnels as they go, which allows both air and water to penetrate deeply. This is a superb benefit – so allow the worms work the soil for you. These components 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 entire tractability of all of the components 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 sharp or waste materials. Ideally, this would be available all year round in bags or bulk.
