Research discovers surprising role of moles in soil health

Uncategorized By Mar 28, 2023

Moles are often viewed as garden pests, but recent research highlights that these digging creatures can significantly advance soil health. Research has found that mole activity can help to improve soil structure and fertility, making it simpler for plants to grow and flourish. Moles create complex networks of tunnels and chambers beneath the soil surface, which improves soil aeration and drainage, breaks up compacted soil, and mixes soil layers to bring nutrient-rich soils to the surface where plants can access. Moles also help keep populations of earthworms and other soil-dwelling organisms in check, which prevents over-grazing of plant roots that reduces plant growth and health.

Research Discovers Surprising Role of Moles in Soil Health

Moles are often seen as pests in gardens and lawns, but recent research has found that these burrowing creatures play a surprising role in soil health. Scientists have discovered that mole activity can help to improve soil structure and fertility, making it easier for plants to grow and thrive.

So what exactly are moles doing underground, and how does this impact soil health? Let’s take a closer look at these fascinating creatures and their relationship with the soil.

Moles and Soil Structure

Moles are burrowers, digging tunnels and creating complex networks of tunnels and chambers beneath the soil surface. This activity can help to break up compacted soils and improve soil structure, which is the arrangement of soil particles and spaces.

When soil is compacted, there is little room for air or water to move through it. This can lead to poor drainage and reduced aeration, which can be bad news for plant growth. By digging tunnels and breaking up the soil, moles can create channels for air and water to move through, improving soil drainage and aeration.

Moles and Soil Fertility

In addition to their role in improving soil structure, moles also play an important role in soil fertility. Their burrowing activity can help to mix up soil layers, bringing nutrient-rich soils to the surface where plants can access them.

Moles also eat earthworms and other soil-dwelling organisms, which helps to keep populations in check. This can help to prevent over-grazing of plant roots by these organisms, which can reduce plant growth and health.

The bottom line is that moles are doing some important work underground, helping to improve soil structure and fertility in their own unique way.


Q: Are there any downsides to having moles in your garden?

A: While moles can provide some benefits to soil health, they can also be a nuisance if their burrowing causes damage to lawns or garden beds. Molehills can be unsightly and may require filling in, and their burrowing activity can damage plant roots.

Q: How can you encourage moles to stay in your garden?

A: If you want to encourage moles to stay in your garden, providing a diverse range of plants and soil types may help. Moles prefer loose, sandy soils and will avoid waterlogged or compacted soils. Providing plenty of organic matter can also help to improve soil structure and fertility, making your garden a more attractive place for moles to burrow.

Q: Are there any natural ways to control mole populations?

A: While there are some chemical methods for controlling moles, these can harm other animals and are not always effective. One natural way to control mole populations is by encouraging natural predators, such as owls, hawks, and foxes, to visit your garden. You can also use physical barriers, such as mesh or wire, to prevent moles from accessing certain areas of your garden. However, be aware that this may also prevent other beneficial soil-dwelling organisms from entering the soil.

In conclusion, moles may be seen as nuisances, but their burrowing activity plays a significant role in improving soil structure and fertility. By providing the right growing conditions and using natural control methods, you can coexist with these creatures and reap the benefits they provide for your garden.
