Pesticides vs. soil fauna: a difficult coexistence. How small animals dwelling in soils do not allow pesticides to be in their homes, tables, and beds. They simply die, starve, or escape somewhere else, if possible. There is a simple methodology that allows to assess the effects of poisons spread onto soils. Using it, we can effectively and in a very cheap way check if there is still life into soil, and try to make sustainable agriculture in stead of greenwashing. The most recent results of specific studies show that there is a chance to get aknowledgement on pesticide use, organic agriculture, and desertification-prone soils. The way is simply to monitor soil fauna, and particularly soil microarthropods, animals smaller than 2 mm that live in soils and participate the fundamental ecosystem services that soils provide, constantly and for free! Multinational corporations know what is their worst enemy, yet they exclude research on these non-target animals, which provide decomposition rates, quality, and resilience to soils, both in agriculture and in the wild.
