Exploratory investigation about the behavior of the atrazine herbicide in an Entic Haplustoll soil of the State of Córdoba

Abstract

In Argentina, due to the intensification of agriculture and the replacement of conventional tillage (CT) by direct seeding tillage (DST), weed control is purely chemical, which promotes more frequent herbicide applications and, usually, with doses higher than for CT. Atrazine is a herbicide that has been and is widely used in the world for different crops, and is frequently found in groundwater. The objectives of this study were to contribute knowledge about the behavior of atrazine in soil with extensive crops in the Province of Córdoba and to analyze the regulatory framework on the use of herbicides in Argentina, specifically in the Province of Córdoba.
