Precision agriculture variable rate technology will be the focus of a July 26 field day at the Kings County, Calif., farm of Ted Sheely, which has become the research lab for a wide array of precision ag practices.

Sheely's farm on the Avenal Cutoff off of Highway 198 in Western Kings County is the focal point of project called Ag 20/20 where aerial imagery is being used to test a wide array of variable rate technology.

Bruce Roberts, University of California Kings County Cooperative Extension farm advisor, is organizing the event which will be held from m 8:30-11:30 a.m.

“We will have precision agriculture equipment on display that was used in variable rate seeding, soil amendment applications and plant growth regulator applications on Ted's farm,” said Roberts.

“Every field on Ted's farm has had some form of variable rate technology used on it, and we'll have field tours to show the results of that work,” said Roberts.

Sheely's farm has been aerially mapped and those maps have been used to vary the rates of fertilizer applications, plant growth regulators and seeding to match soil and plant conditions. Sheely also has several tractors equipped with Global Positioning System (GPS) guidance systems, which are an integral part of his precision agriculture/variable rate programs.

Several presentations

There will be presentations from government and university researchers and commercial firms who have worked on Sheely's farm.
