Earthworms are beneficial for the soil in our gardens as they aerate the soil by digging tunnels, promote the mixing of different soil layers, and break down organic matter into essential nutrients for plants.
Earthworms contribute to the increase in soil fertility by promoting the decomposition of organic matter. Their activities of digging and ingestion help to break down plant debris, dead leaves, and other organic matter present in the soil. By digesting these materials, earthworms transform them into humus, a component rich in essential nutrients for plants. Humus improves soil structure and promotes water retention, helping plants to grow and thrive. Thanks to this action, earthworms contribute to maintaining a biological balance in the soil, promoting the growth of crops and the overall health of the garden ecosystem.
Earthworms contribute to improving soil structure by naturally aerating it through their movements and promoting the mixing of different layers of soil. Their burrows help to decompact the soil and facilitate deep root penetration for plants. By stirring the soil, earthworms also promote the circulation of water and nutrients in the soil, which is essential for plant development. Thanks to their actions, the soil structure becomes more stable and conducive to crop growth. Earthworms thus help create a favorable environment for microbial life and plant development in our gardens.
The presence of earthworms in the soil promotes increased air and water circulation. By digging tunnels, earthworms allow for better soil aeration, thus promoting the development of beneficial microorganisms. These tunnels also facilitate the infiltration of rainwater into the soil, thereby reducing runoff and erosion. Furthermore, the passages created by earthworms allow for better water retention in the soil, limiting the risk of flooding during heavy rains. By improving soil porosity, earthworms contribute to better water regulation, promoting plant growth and overall health of the underground ecosystem.
The regular presence of earthworms in a garden generally indicates that the soil is healthy, balanced, and free from harmful chemical pollutants that could affect biodiversity.
Earthworms do not have lungs: they breathe directly through their moist skin, which is why it is crucial to preserve soil moisture for their survival.
Yes, the intensive use of pesticides or chemical fertilizers significantly reduces earthworm populations by disrupting their habitat and can even kill them directly. Instead, choose gentle or organic fertilizing methods to preserve their presence.
Earthworms are generally beneficial. However, in excessive numbers, some species can eventually create unsightly piles of waste on lawns. The benefits-to-drawbacks ratio remains very much positive, and these cases are quite rare.
Earthworms primarily feed on decomposing organic matter, such as dead leaves, plant residues, or compost. They absorb this material and transform it into excrement that is rich in essential nutrients for plants.
Sure! Here's the translation: "Yes, they can come from different types of soils, but they prefer loose soils that are rich in organic matter and have good moisture. In very clayey or very sandy soils, regular addition of organic matter will help ensure their sustainable establishment."
To naturally attract earthworms, focus on creating a garden rich in organic matter (compost, decomposed manure), limit intensive tilling, keep the soil covered (with plant mulch) to retain moisture and freshness, and avoid excessive use of pesticides or chemical products.
