Precision agriculture is an ever-evolving approach to farming in which producers use GPS, aerial images and geographic information systems software as well as sensors installed on farm machinery to gather detailed data about how soil fertility, terrain, weed populations, crop yields and other conditions affecting crop growth vary within a given field.

Fulton said that kind of information is helping Alabama farmers develop more refined understandings of their operations’ potential and limitations and make decisions that maximize their crop yields.

Two Lawrence County farmers, grain producer Don Glenn and cotton farmer Larkin Martin, were among the first growers in the state to venture into the age of precision ag when it was in its infancy, and both credit the tools of precision farming for helping them boost their productivity and profitability. They also acknowledge that the ongoing precision ag research scientists are conducting through the Alabama Precision Ag Program at Auburn and the training and technical help the Alabama Cooperative Extension System provides have been essential in advancing the technology.

“The program has provided invaluable assistance in cutting through the marketing hype to show what really works in the field,” said Glenn, and Martin, who believe the practical use of precision agriculture will be essential to successful farming in the future. They said researchers’ work to quantify the value of the various precision ag tools and Extension’s efforts to keep Alabama farmers informed “have brought and should continue to bring real value to agriculture in Alabama.”

Auburn scientists calculated the estimated savings realized through use of precision ag technologies based on the number of farmers they consult, the number of farmers enrolled in National Resources Conservation Service precision ag programs and the average savings for various technologies that have been determined through research, Fulton said.
