摘要：Using information from precision farmer surveys conducted in the southern United States in 2005 and 2013, we evaluated changes in the use of precision farming information sources among cotton producers. Although Extension remains an important source for producers interested in precision farming information, the percentage of cotton producers using Extension to obtain precision farming information has decreased over time. Results from our study should motivate Extension professionals to re-evaluate the precision farming information they provide to producers and the practices they use to provide such information in efforts to maintain Extension's importance as an information source.
