The influence of soil p roperties on pesticide toxicity to soil invertebrates

Worms in Danger? That Depends on the Soil

Pesticides can be harmful to small soil animals such as earthworms and springta ils, but the extent of the damage appears to depend on the soil they live in. Toxicologist Bart van Hall discovered that some soils retain pesticides better, making them less toxic to animals. Other soils re lease the substances more quickly, increasing their harmful effects.< /p>

Better Testing Needed
Van Hall warns that s tandard laboratory tests often use only one type of soil. This does n ot provide a complete picture of how pesticides behave in nature. "If we know that a certain pesticide is more dangerous in sandy soil tha n in clay soil, farmers can take that into account," he explains.

More Sustainable Use of Pesticides
Van Hall's research helps promote the safer use of pesticides and refine regulat ions. This can contribute to healthier soil, more sustainable land us e, and a better balance between food production and nature.
