Atrazine enables U.S. farmers to grow more crops with less of everything — less land, less water, less labor, less energy and less carbon released into the atmosphere. Conservation tillage and related practices, made possible in part
by atrazine and other triazine herbicides, have led to a 34% decrease in soil erosion from U.S. farmland over the past three decades.
Stewarding natural resources helps support climate resiliency and keeps farmers productive, profitable, and sustainable.
Less Land Lost
The use of triazine herbicides reduces aggregate soil erosion by 56-85 million tons per year, providing $210 million to $350 million in benefits,
annually. Thanks to atrazine and related herbicides, an estimated 210,000-310,000 acres of U.S. land can be used for purposes other than
growing crops. These non-cropped acres contribute not only to reduced soil erosion and less pollution from input use, but they also improve habitat for birds and pollinators.
Safe Streams
From 2002 to 2012, concentrations of atrazine decreased in more than one-half of 60 U.S. streams and rivers studied, and increased in only about one-third of these streams, according to a new study by the U.S. Geological Survey National Water Quality Program. The
streams and rivers are in a range of land-use settings.
Overall, the atrazine stream concentrations trends were mainly downward between 2002 and 2012, with some sites showing upward trends. Nationally, the amount of harvested corn acres increased from 2002–2012 by >60,700 km2 (15
million acres). The growth in corn acres was likely in areas not historically dominated by corn acres and is reflected in the scattered streams that showed upward trends in atrazine stream concentrations.
Clean Air
Atrazine and other triazine herbicides reduce consumption of diesel fuel for tillage by 18-28 million gallons per year, implying a decrease in carbon dioxide emissions of 180,000-280,000 metric tons per year.
