Which organism is considered the best tiller of the soil?

Earthworms are often regarded as the best tillers of the soil due to their essential role in soil health and structure. As they burrow through the ground, they create channels that improve aeration and drainage, allowing water and air to penetrate more deeply into the soil. This activity enhances root growth for plants and facilitates access to nutrients.

Moreover, earthworms contribute to the breakdown of organic matter, which further enriches the soil. Their digestive process transforms organic materials into nutrient-rich castings, which act as a natural fertilizer. This dual action of aeration and nutrient cycling makes them invaluable in agricultural practices for promoting soil fertility and crop yields.

While other organisms, like ants and termites, also play roles in soil mixing and aeration, earthworms are particularly noted for their efficiency in improving soil structure and providing essential nutrients, making them the most effective tillers among the options given.
