The Role of Soil Manufacture in Sustainable Landscaping

Posted on

Sustainable landscaping is more than just a trend—it’s a necessity. With climate change, soil degradation, and biodiversity loss becoming increasingly concerning, the way we approach landscaping must evolve. A critical component of this transformation is soil manufacture, an innovative process that enhances soil health while reducing waste and environmental impact.

Soil manufacture plays a key role in sustainable landscaping by creating high-quality soil blends tailored to specific needs. Whether it’s improving drainage, increasing fertility, or reducing reliance on chemical fertilisers, manufactured soils offer an eco-friendly alternative to traditional soil use. In this blog, we’ll explore how soil manufacture benefits sustainable landscaping, what makes it a superior choice, and how you can integrate it into your landscaping projects.

1. What Is Soil Manufacture?

Soil manufacture refers to the process of creating engineered or blended topsoils using site won subsoils with a combination of organic and inorganic amendments. This method makes topsoils for various landscaping applications while reducing the need for natural soil extraction.  Compliance to BS3882 is possible, but not always needed.

  • Key Components: Manufactured soils typically include site won subsoils or poor quality topsoils, with a selection of the following:
    • Green waste
    • Composted sewage cake
    • Reservoir sludge
    • Inorganic fertilisers
    • Paper crumble
    • Lime
    • Kiln ash
  • Why It Matters: Using site subsoils can save a HUGE amount of money and reduce materials taken to tip.  In addition natural topsoil is a finite resource and takes thousands of years to form, but soil manufacture provides a quicker and more sustainable alternative.
  • Customisation: Depending on the subsoil, it can be tailored to specific conditions, whether for gardens, sports fields, green roofs, or urban landscapes.

2. Environmental Benefits of Manufactured Soil

Using manufactured soil contributes significantly to sustainable landscaping by reducing environmental impact. Here’s how:

  • Minimises Soil Depletion: Extracting natural topsoil can lead to erosion and habitat destruction. Manufactured soil helps preserve natural resources.
  • Reduces Waste: Organic waste materials, such as composted green waste, are repurposed rather than sent to landfill.
  • Carbon Sequestration: High organic matter content in manufactured soils can capture and store carbon, helping to mitigate climate change.
  • Better Water Retention: Many engineered soils improve water retention and drainage, reducing irrigation needs and preventing runoff pollution.

3. Enhancing Soil Fertility for Healthier Landscapes

Manufactured soils are designed to optimise nutrient content, supporting healthier plant growth and reducing the need for artificial fertilisers.

  • Nutrient-Rich: Compost and organic matter provide essential nutrients such as nitrogen, phosphorus, and potassium.
  • Improved Microbial Activity: Healthy soils encourage beneficial microbes, which enhance nutrient cycling and plant resilience.
  • pH Balancing: Manufactured soil can be adjusted to suit the needs of different plant species, ensuring optimal growth conditions.

4. Applications of Manufactured Soil in Landscaping

Soil manufacture is revolutionising various landscaping sectors. Some key applications include:

  • Urban Landscaping: Green roofs, public parks, and roadside plantings benefit from soil blends that improve drainage and support plant growth.
  • Gardens and Lawns: Custom soil mixes can enhance soil structure, ensuring healthier lawns and flower beds.
  • Sports and Recreation Areas: Specialised soils provide the right balance of compaction and permeability for sports fields and playgrounds.
  • Erosion Control: Blended soils can help stabilise slopes and prevent soil loss in vulnerable areas.

5. How to Choose the Right Manufactured Soil for Your Project

Selecting the best soil blend depends on your landscaping needs. Consider the following factors:

  • Soil Composition: Look for a mix that balances organic matter, minerals, and drainage properties.
  • Application Requirements: Different plants and environments require specific soil characteristics—check pH levels, nutrient content, and texture.
  • Sustainability Credentials: Choose suppliers that use recycled materials and eco-friendly production methods.

Conclusion

Soil manufacture is a game-changer in sustainable landscaping. By reducing soil depletion, repurposing waste, and optimising soil health, this innovative approach supports greener and more resilient landscapes. Whether you’re revitalising a garden, designing an urban park, or working on a large-scale landscaping project, incorporating manufactured soil can help you achieve long-term sustainability while enhancing plant health and ecosystem balance.
