Fate of Atrazine in Argentinean Soils: Atrazine in Soils Susana Hang

In this book are shown the results of the atrazine behavior in Argentinean, conducted between 2001 and 2006. In the first work it was studied the behavior of atrazine in surface soils, and evaluated the effect of land use and how it affects the ability of soil to remove residual atrazine. In the second study it was evaluated two soil profiles characteristic of the province of Córdoba, and in each horizon, the effect of soil properties on the retention and degradation of atrazine mineralization was evaluated. The third study aimed to recognize the distribution along the profile of the soil's ability to mineralize atrazine. The soil sterilization was carried out to quantify chemical and biological degradation of atrazine. In the fourth and fifth paper it was analyzed different strategies of winter weed control and how weed management influenced on the atrazine persistence. In the sixth and final paper it is presented an original proposal to identify soils with rapid mineralization capacity of atrazine, based in corn crop history where atrazine is used. As a tool to reconstruct the history of the lot was used satellite images.
