Ecotoxicology

Electrical weeding is a nonchemical weed control method that uses high-voltage energy without introducing harmful substances into the environment. Though not regulated under European chemical laws, Zasso conducted extensive ecotoxicological studies to assess its impact on soil organisms and ecosystems. Field trials in grasslands, orchards, and agricultural fields—performed by independent labs such as BioChem agrar GmbH and CTIFL—showed that Electroherb™ applications had no significant adverse effects on earthworms, springtails, or soil microarthropods. A separate study by the Univeridade Estadual Paulista (UNESP) confirmed that microbial respiration, biomass, and enzymatic activity remained stable or improved post-application. Compared to mechanical and chemical methods, electrical weeding demonstrated superior preservation of soil structure, biodiversity, and microbial health. These findings confirm the technology's environmental safety, highlighting its suitability as a sustainable, residue-free alternative to herbicides. Electrical weeding thus emerges as an effective and ecologically responsible solution for modern agriculture, with minimal impact on soil biota and long-term ecosystem integrity.
