Topsoil vs Compost: What Should You Use?
But what matters even more is the soil; it is essential for healthy plants that serve as a foundation for all your landscaping and gardening efforts. Topsoil and compost are the top two favourites, but they serve two different purposes in a garden and have their own benefits. At UK Construction Waste Co, we know how important soil selection is.
Key Takeaways
Topsoil provides a nutrient-rich base ideal for large-scale landscaping, establishing lawns, and filling raised beds.
Compost is excellent for boosting soil fertility, improving soil quality, and serving as mulch to retain moisture and regulate temperature.
Topsoil and compost can be combined to create an optimal growing medium, balancing nutrients, structure, and water retention.
Mixing topsoil and compost in a 60:40 ratio ensures even distribution of organic matter and nutrients, supporting diverse gardening needs.
Understanding Topsoil and Compost
What Is Topsoil?
This is the uppermost layer of soil, consisting of weathered rock, sediment, organic debris, air, water, and microorganisms that form soil bacteria that is vital for the growth of plant roots. It is usually used as backfill in large areas, in terracing a backyard and as the base from which we grow lawns and flower beds.
What Is Compost?
Compost is decayed and decomposed organic material made of either manure, kitchen waste or garden waste. It is a soil enhancer and a powerful plant growth stimulant and soil conditioner. The best part is that it is excellent at enriching garden soil, resulting in robust plant growth.
Key Differences Between Topsoil and Compost
Nutrient Content
Readily available type is rich in natural nutrients and organic matter, but quality of topsoil varies significantly depending from where it comes. On the other hand compost is teeming with nutrients and bacteria, to the point where it's a literal feast for your plants.
Water Retention
Topsoil also holds moisture and it is ideal for holding water in soil. Compost will help retain moisture, but is somewhat quickly utilised when alone. When combined with native soil, compost provides both the water holding capacity of a silt or clay soil and a soil medium which will provide a full range of nutrients in a balanced form for all plants.
Structure
Topsoil forms a dense base for the roots of thousands of plants. Compost enhances the condition of the soil it is mixed with because of the copious amounts of organic matter that it adds to the soil, contributes to aeration and improves root penetration.
When to Use Topsoil
Large-Scale Landscaping
Topsoil can be used for large landscaping projects which demand a solid, nutrient-rich foundation. Useful for laying new turf, garden bed fill and levelling uneven ground. Topsoil gives the basic support system to develop plants over a vast area.

It provides the perfect balance of nutrients, water retention and structure to assist with grass seed germination and root development. The top soil stimulates your lawn with a strong foundation from which to be victorious.
Filling Raised Beds
Topsoil helps build raised beds for vegetables, or flowers. It holds the plants up and holds and retains the moisture in the soil, helping to reduce the need for frequent watering. You can make the raised bed even richer by topping up with compost and have the best of both worlds.

Soil Amendment

This is a very good practice for heavy sharp clay soils or sandy soils that are structureless and low in fertility.
Mulching
You can use compost as a mulch to prevent the growth of plants, it helps to retain soil moisture, and it has a temperature-regulating effect in the soil. A layer of compost around plants can protect the soil surface and slowly release nutrients into the environment, encouraging continued plant health.
