The study investigates the impact of long-term vinasse application from sugarcane bioethanol production on soil properties and herbicide effectiveness in a subtropical agroecosystem in Tucumán, Argentina.
Findings show that vinasse increases soil pH, electrical conductivity, and organic carbon, which in turn affects the dissipation rates of atrazine and ametryn herbicides.
The research suggests that while vinasse application reduces groundwater contamination risks from these herbicides, it also decreases their effectiveness for weed control, indicating a need for modified herbicide management practices.
