Precision ag field day set July 24

The University of California and USDA are teaming up once again for a San Joaquin Valley precision agriculture field day July 24 on the Ted Sheely Farm west of Lemoore, Calif.

Sheely has been heavily involved in precision agriculture, virtually turning his farm into a laboratory as part of the national Ag 20/20 program where scientists and farmers are attempting to cut cost and increase yields by 20 percent using precision agriculture technology.

Sheely has tried just about everything on his farm and researchers and Sheely will give a progress report on the various projects.

The program begins at 9 a.m. and closes at noon.

Besides the presentations below, there will be field demonstrations and static displays of guidance systems, variable rate applicators, control systems for ground and air GPS systems.

Welcome — Bob Hutmacher, cotton specialist, UC Cooperative Extension.
