COLUMBUS, Ohio — The benefits of adopting precision agriculture technologies far exceed the costs required to use such systems, according to a 2003 survey of Ohio farmers.

The survey, which analyzed the adoption and use of 18 precision farming components, found that over half of the respondents believed that their overall precision farming system was useful enough to justify the costs. Respondents also commented that precision farming components, such as variable rate application of lime, phosphorus and potassium, georeferenced soil sampling and satellite field photography were beneficial to their farming operations.

Marvin Batte, an Ohio State University professor and agricultural economist who led the study, said that such results might aid in the decisions of those farmers looking to adopt such technologies.

“The survey shows how others who adopted this technology are evaluating it and what individual components they are finding most useful,” said Batte. “It also helps growers make careful decisions on what technology to adopt so that it fits their operational needs. Not every precision agriculture component is for every farmer.”

Batte will be on hand at the Conservation Tillage and Technology Conference in Ada, Ohio Feb. 27 to discuss the results of the survey. About 2,500 farmers were contacted and half responded to the study. Similar to a study conducted in 1999, the survey analyzed the adoption and use of a variety of precision agriculture components such as yield monitors, guidance systems, boundary mapping and a host of GPS-related techniques. Characteristics such as farmer age and educational background, as well as farm size, were also analyzed to determine their impact on precision agriculture use.

“Overall, precision farming adoption has increased. About 30 percent of farmers surveyed had adopted at least one precision farming component, about eight percentage points higher than in 1999,” said Batte. “And the average adopter uses about four precision farming components.”

The most widely adopted precision agriculture components were georeferenced grid soil sampling, variable rate application of lime, phosphorus and potassium, and the use of a yield monitor, all of which increased in use by an average of 7 to 12 percent from four years earlier.

One interesting result was the adoption of precision guidance systems, such as light bars or auto-steer technologies. Over 5 percent of respondents have adopted some form of guidance system, whereas in 1999, such technology was virtually unheard of and unattainable.

“You can say that such technology is being adopted rather briskly,” said Batte.

The survey also revealed that the rate of adoption and use of precision agriculture technologies is dependent upon a variety of characteristics, such as the size of the farm, age of the farmer and his/her employment status.

“Larger farms lead the way in use and adoption of precision agriculture,” said Batte. “For variable rate application of P, K and lime, which usually is priced on a per acre basis, adoption rates are just over twice as large for the largest farms relative to the smallest sales group. For technologies such as yield monitor, GPS receiver, and precision guidance where a fixed investment is required, adoption is 10 to 15 times greater for the largest than for the smallest farms.”

Fifty-eight percent of those surveyed who have adopted one or more precision agriculture components have gross farm sales of over $500,000 a year.

Farmers age 35 or younger tend to adopt such technologies much quicker than those in older age groups. Nearly 50 percent of young farmers have adopted precision agriculture technologies, as opposed to 31 percent of those aged 50-65. And farmers who work full-time on their farm are more likely to adopt precision agriculture technologies than those farmers who work part-time on the farm or work full-time at another job.
Some technologies that farmers have not embraced include variable rate seeding, variable rate application of pesticides and GPS or sensor-directed spot spraying of pesticides and herbicides.

Batte speculates the rate of adoption of such components is slow because not enough information is available to make recommendations or accurately apply applications for maximum benefit.

The Conservation Tillage and Technology Conference will be held Feb. 26-27. The event is designed to bring together speakers from land-grant universities, the farming sector and agricultural industries and organizations to discuss a wide range of topics including agriculture-related panel discussions, precision agriculture, soil fertility, water quality, insect and disease management, strip-till research, value-added farming, crop management and producer programs. Over 65 sessions will be offered over the two-day conference with nearly 70 different speakers.

The tillage conference is being sponsored by Ohio State University Extension, Northwest Ohio Soil and Water Conservation Districts, U.S. Department of Agriculture Natural Resources Conservation Service, USDA Farm Service Agency and the Ohio No-Till Council.

Early registration is $25 per day or $40 for both days. Registration after Feb. 18 is $35 a day or $50 for both days.
