Pesticides that are used on nearly every acre of conventional farmland in the United States are reducing crop yields by one-third.
Pesticides disrupt chemical signaling between plants and impair symbiotic nitrogen fixation (SNF), an important process for plant growth. At least 30 pesticides are known to disrupt SNF, including the most widely used pesticide in the United States, Roundup.
SNF plays a critical role in supporting crop yields and environmental quality, and well-functioning SNF can greatly reduce farm production costs. In Brazil, soybean SNF reduces production costs by $1.3 billion each year.
