While AgSource Laboratories is not “older than dirt,” the organization does have a 50 year history of analyzing soil and contributing to the overall health and productivity of thousands of acres of land. What started as a county extension milk lab has grown into a full service agronomy lab, complete with nutrient management planning and GPS soil sampling services. AgSource Laboratories, in Bonduel, Wis., became a part of AgSource (then called ARC, Agricultural Records Cooperative) in August 1967. That first year, the lab processed just 5,301 soil samples. Today, the lab can analyze that many samples in under two days.
