Worms in Danger? That Depends on the Soil
Pesticides can be harmful to small soil animals such as earthworms and springtails, 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 release the substances more quickly, increasing their harmful effects.
Better Testing Needed
Van Hall warns that standard laboratory tests often use only one type of soil. This does not provide a complete picture of how pesticides behave in nature. "If we know that a certain pesticide is more dangerous in sandy soil than 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 regulations. This can contribute to healthier soil, more sustainable land use, and a better balance between food production and nature.
