History and Clientele
Since 1982, our business has grown steadily each year. The majority of
our business is providing GPS grid pattern soil testing programs for
farm managers, absentee landowners, and farmers. We were the first
company in Central Illinois to make site-specific fertilizer
recommendations. Today, we make fertilizer recommendations on nearly
600,000 acres in Illinois, Indiana and Iowa.
