Maintaining living roots in the soil

At a time of growing challenges related to environmental protection, a changing climate and soil degradation, regenerative agriculture is becoming a key tool for building a more sustainable future. One of the fundamental practices of this approach is maintaining living roots in the soil. This means keeping fields covered with vegetation all year round – there are no living roots without living plants.

Why is this so important? Let’s take a closer look at this method, which not only improves soil health but also supports agricultural ecosystems.

The role of roots in the soil

Plant roots are not just “anchors” that hold plants in the ground – they also play a key role in building healthy soil structure and give the soil the right biological, chemical and physical properties.

What exactly are the benefits?

Soil protection: plant roots protect the soil from erosion caused by wind and rain. When the soil is left bare, rain and wind can easily destroy its structure, leading to the loss of valuable organic layers. Cover crops, growing in winter or between main crops, help maintain its structure.

Better water storage: roots act as natural “channels” that allow water to penetrate deep into the soil. Soil that regularly has access to living roots is better able to store water, which is especially important in the face of climate change and periods of drought.

More organic matter: as roots decompose, they supply the soil with organic matter, which supports the development of microorganisms and increases its fertility.

Better nutrients: plants with deep roots can take up nutrients from deeper soil layers that are normally out of reach for shallow-rooted crops. At the end of the season, these plants leave nutrients in the soil that are available to the following crops.

Support for microorganisms: living roots support microorganisms and other soil organisms, such as earthworms and fungi. These organisms not only help break down organic matter but also improve the availability of nutrients to plants.

CO₂ reduction: living roots help capture carbon from the atmosphere, which limits greenhouse gas emissions.

What benefits does this bring to farmers?

Maintaining living roots in the soil brings farmers many benefits. Better soil structure and a greater capacity to retain water reduce the need for irrigation and protect against erosion, which lowers cultivation costs.

Living roots also help plants take up nutrients more effectively, so the use of synthetic fertilisers can be reduced.

Healthier soil, richer in microorganisms, produces higher yields without the need for intensive use of chemicals. In the long run, farmers gain more stable crops that cope better with difficult conditions such as drought.

How can you introduce this practice on your farm?

To introduce the practice of maintaining living roots in the soil effectively, it is worth using several strategies:

1. Cover crops: after the growing season, it is worth sowing cover crops (e.g. clover, rye, lucerne). They will continue to photosynthesise and protect the soil over winter.
2. Diverse crops: introducing greater crop diversity, especially crops with different root types, can significantly improve soil health.
3. Agroforestry and perennial plants: planting trees and shrubs together with agricultural crops (known as agroforestry) keeps living roots in the soil permanently, which benefits its health in the long run.
4. Minimising ploughing: reducing ploughing, for example by using no-till systems, helps preserve the natural soil structure and healthy roots.

At a time when healthy soil is the key to the future of agriculture, practices such as maintaining living roots in the soil are essential for protecting the environment and using natural resources responsibly. They bring many benefits for the functioning of nature, but also deliver measurable gains for farmers.
