Why are buried earthworms difficult to catch?

1. When the temperature rises, the water in the soil will evaporate easily, making the soil dry. This makes it difficult for earthworms to survive and move in the soil. They will move to the surface of the soil in search of water or a wetter environment.

2. In wet soil, microorganisms will multiply rapidly and consume oxygen in the soil. This reduces the oxygen content in the soil, makes it difficult for earthworms to survive and move, and also moves to the soil surface.

3. After lodging, the radiation intensity of the sun increases. After the water in the soil is irradiated by the sun, it will produce a lot of heat energy, which will raise the temperature in the soil, which also brings difficulties to catch earthworms.

If you want to catch the fallen earthworm, you can choose to catch it on the wet soil surface in the morning or at night, or pay more attention to the weather forecast at ordinary times and choose cloudy or cloudy weather to improve the success rate of catching it.
