River Valley Agronomy Gets It Done 

YieldVantageWhat’s important to the farmer when it comes to crop production? Getting things done.

That’s why River Valley Cooperative’s agronomy experts spend most of their time in the country throughout eastern Iowa and western Illinois, working one-on-one with growers. We’re not here to sell you stuff. We want to be a trusted partner who provides the agronomy solutions you need.

This commitment extends beyond our sales staff to River Valley’s location managers, professional applicators, skilled mechanics, and agronomy support staff. You can rely on us to make agronomy technology work for you, saving you time and maximizing your productivity throughout the growing season.


Caring for the land

Since environmental respect comes naturally to anyone who cares for the land, you can also count on River Valley to help you find effective ways to protect water resources and conserve the soil. We can advise you on cover crops like rye, oats, and tillage radishes.

After all, agronomy is not just about getting things done—it’s about doing the right things. We can help with seed, seed treatments, tissue testing, variable-rate nutrient application, custom application of crop-protection products, grid and whole-field soil sampling, field scouting, and more.
