Broadly, there are three types of topsoil available such as natural topsoil, skip waste soil, and blended soils. Natural topsoil is highly variable in quality and availability and ranges from an acidic, nutrient-deficient sand, into a strongly alkaline silt-loam, and also 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 quite expensive. Natural topsoil always contains a bank of seeds, including perennial and annual weed seeds; and may 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 as a result 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 result of the materials derived from construction and demolition operations, which are then screened.

Skip waste lands are a combination 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 may often have elevated levels of zootoxic and phytotoxic contaminants. Although skip waste soil can seem 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 mixed to form a growing medium. Composting is a great start. By turning organic materials into compost, you are using a huge variety of substances and so putting back a excellent range 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 the soil. Do not dig over your soil.
It’s not necessary to turn over, or twice dig your soil, and it can destroy both the soil texture and the micro-organisms that are of great advantage to your soil. Besides, you don’t 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 enables both air and water to penetrate deeply. This is a superb benefit – so let the worms work the soil for you. These elements can be prime natural 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 elements of a mixed soil and to have them tested 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 from contamination with no sharp or waste materials. Ideally, this would be available all year round in bags or bulk.
