About US

We know agriculture because we were born into it.

In 1959, AgSource was formed to serve Wisconsin dairy farmers. What began as a regional, dairy records processing cooperative has now grown into the AgSource of today – serving industries that span the entire agricultural ecosystem.

From cutting-edge soil, plant tissue, and water testing, to agronomic consulting and full-service DHI testing, AgSource is at its core, a source of truth.

One test at a time, we help our clients make the best decisions – always grounded in data.
