Key Agricultural Services Inc.'s began grid soil sampling in 1977.  We incorporated GPS into the system the early 90's, and started using GPS yield monitor data as a component in determining variable rate fertilizer requirements in the early 1990's.  We have been at the forefront of Precision agriculture ever since.  Our diverse and detailed knowledge of the physical and chemical properties of soil, crop production practices, agronomy, and GIS systems gives us a background and level of expertise second to none. 

A major specialty of Key Agricultural Services, Inc. is to observe management practices, identify potentially problematic components of management activities, make recommendations to minimize the effects of the practices on agricultural crop production, and increase on farm efficiencies and profit.
