AgSource

AgSource is an agricultural services company serving farmers with laboratory testing, dairy records processing, herd management and agronomic consulting. Founded in 1959 as a farmer-owned dairy records processing cooperative, it remains focused on delivering accurate, timely data to support decisions on the farm. The company operates in Wisconsin and across the Midwest United States, working in agriculture, dairy farming and agronomy.

Its laboratory testing services cover soil, plant tissue, water and manure, delivered through a network of six laboratories across the Midwest. Alongside these, AgSource provides soil health analysis and agronomic nutrient management recommendations derived from test data, as well as milk recording and herd management services that trace back to the company's founding business.

The company's stated aim is to serve as a reliable source of truth for farm operations. Team members bring practical agricultural experience and knowledge of farming challenges firsthand, and the organisation points to a long-standing presence in its communities since 1959.
