摘要：Cotton farmers in Alabama, Arkansas, Florida, Georgia, Louisiana, Mississippi, Missouri, North and South Carolina, Tennessee, and Virginia were asked where they obtained information about precision farming. Farmers use Extension as a source of precision farming information, but in combination with other sources, including media, crop consultants, trade shows, and other farmers. Farmers using Extension as a source of information tend to be younger, with more education and higher incomes, compared to producers not seeking information from Extension. Understanding the profiles of producers using Extension resources for precision farming information may help Extension design programs to improve information delivery to clients.
