If farming is like football, harvest is a soybean farmer’s championship game. They’ve clocked countless hours planning, preparing and nurturing their plants to provide nutritious food for South Dakota’s families. Now, it’s time to discover the results. Since farmers are always thinking ahead, and looking for ways to improve, it’s also a time for them to evaluate how their strategies worked and make even better plans for next year.
Last fall, we chatted with David and Miriam Iverson as they prepared for harvest on their farm in Brookings County. As combines began rolling this season, we checked back in with the family to see what updates they made and how they’ve paid off.
“We’ve had a really good growing season this year, and overall the crop looks really good,” said David. “When thinking about changes and improvements moving forward, we typically consider factors like the resources that will be needed, harvest costs and balancing the workload.”
For South Dakota soybean farmers, sustainability means doing the right thing for the environment and continuously improving the land for future generations. That’s why farmers evaluate their practices each season and make adjustments accordingly.
The Iversons made a few changes this year, such as increasing the amount of soybeans they planted and cutting back a bit on corn. They also decided to dabble in a new soybean variety and planted 300 acres of non-GMO high-oleic soybeans for the first time. High-oleic soybeans provide a source of vegetable oil for the food industry that is low in saturated fat, high in unsaturated fat and trans-fat-free.
Since they’re food-grade soybeans, the high-oleic variety is managed and harvested a little differently. Extra elbow grease is needed to clean out the combine, trucks, grain bins and augers before they’re harvested, and farmers have to use a slightly different crop protection strategy. However, their premium price is worth the extra effort. David said they’ve grown well on his farm so far and he may look to plant more next year.
The Iversons also use tools like soil sampling to determine which crop nutrients they’ll use for the next growing season.
“Once everything is harvested, I work with an agronomist to pull soil samples. We do this when we’re ready to rotate crops because the requirements vary for different plants,” explained David. “We send our samples to a lab, and they send back a full nutrient analysis so when a field is changing from soybeans to corn, we know exactly what that corn crop will need in the upcoming year.”
By working with experts to determine specific nutrient needs, David can be efficient with fertilizers and only apply exactly what is needed. Preserving crop and soil health is important for sustainable farming because it supports the longevity of the land, minimizes waste and maintains a healthy environment for future crops to flourish in coming seasons.
“Sustainability to me has a few different legs,” shared David. “One is maintaining soil health. There’s a lot of agronomy that goes into that aspect. There’s also the economic part of it. Improving the soil helps economically, and to be sustainable long term, you have to make decisions that financially benefit the farm.”
David’s family has passed their farm down for four generations and have achieved success through the changing times by implementing new techniques and best practices.
“The biggest aspect in recent years has been adding technology like autosteer and yield mapping,” said David. “That data helps us make better crop decisions and improve parts of the farm that are producing less.”
Today’s technology helps farmers interpret harvest and yield data of past years to grow safe and healthy food in the future. Whether reflecting on this year or planning for the next, harvest is special time for soybean farmers.

Hungry for Truth is an initiative about food and farming funded by the South Dakota soybean checkoff. The goal is to connect South Dakotans with the farmers who grow and raise their food.
