General Info

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. Our soil-testing lab is staffed by qualified laboratory personnel, all with 10-plus years lab experience. We take great pride in our internal quality control program. By measuring one known standard for every four samples run through the lab, we do our utmost to provide customers with accurate, reliable results. ASM, Inc is a long-time member of the Illinois Soil Testing Association, and cooperates with their quality check programs. Doug Walk, Field Operations Manager, B.S.
