On behalf of our farmer-members, Landus is honored to support the full circle of the food chain—from seed to commodity, from product to feed and from cow to the kitchen table. 


Something That Matters

The farmer-members of Landus are an integral part of a remarkable story that begins with planting AcreEdge® seed and includes working with our agronomists to maximize yields.

Farmers sell their harvested soybeans—which represent a season’s worth of sacrifice, hard work and hope—back to Landus.

These soybeans, in turn, are processed at Landus facilities and transformed into a line of specialized, high-quality, soybean meal-based dairy cow feed that is distributed worldwide.

Dairies in six continents use SoyPlus, SoyChlor and PasturChlor to help improve cow health and performance for optimum productivity.

And eventually, the farmer-members of Landus find the dairy products—from milk to cheese, baby formula and more—in their grocery stores.

The History of Landus is the History of Iowa Cooperatives

The earliest known roots of Landus developed in 1888 with Farmers Elevator and Livestock Company in Jordan, Iowa.

Over the years, dozens of elevators, grain companies, feed millers and suppliers, agronomy facilities and even a hardware store and energy company have merged, changed hands and banded together to remain relevant and strong in a global marketplace.

The transformations culminated in 2016 with the founding of Landus. Take a look at our family tree, which lists the 60+ companies that helped build Iowa agriculture.
