Improving soil health through sustainable farming

Shawn Feikema combines tradition with modern soil practices

Meet Shawn Feikema, a third-generation farmer from Luverne, Minnesota, who operates a 7,000-acre farm alongside his family. Shawn's daily mission is shaped by two questions: how to maximize efficiency and how to leave the farm better for future generations. His approach reflects a balance of tradition and modern sustainability.

Shawn's farm produces corn, soybeans, small grains, and hay, while also managing a cattle feedlot that markets 6,000 head of cattle annually.

The farm employs a systems approach, creating a symbiotic relationship between crop production and livestock. Manure from the feedlot serves as an organic fertilizer, replacing commercial alternatives and enriching soil health.

“It’s really a systems approach to soil health is how I look at it,” Shawn explained. “We use everything the soil gives us, and we return it back to the field.”

Recent regulatory changes in Minnesota restricted manure hauling during peak months, prompting Shawn to build a stacking pad for storage. With support from USDA’s Environmental Quality Incentives Program (EQIP), the farm installed a waste storage facility and other conservation practices, covering 90% of the cost.

This project resolved a major challenge, ensuring the farm’s long-term sustainability. Shawn emphasizes his core principle: “We do the best we can with what God has given us. This is the Earth he’s given us, and we’re to make the most of it.”

US Soy: Pig growth is impaired by soybean meal displacement in the diet

Video: US Soy: Pig growth is impaired by soybean meal displacement in the diet

Eric van Heugten, PhD, professor and swine extension specialist at North Carolina State University, recently spoke at the Iowa Swine Day Pre-Conference Symposium, titled Soybean Meal 360°: Expanding our horizons through discoveries and field-proven feeding strategies for improving pork production. The event was sponsored by Iowa State University and U.S. Soy.

Soybean meal offers pig producers a high-value proposition. It’s a high-quality protein source, providing essential and non-essential amino acids to the pig that are highly digestible and palatable. Studies now show that soybean meal provides higher net energy than current National Research Council (NRC) requirements. Plus, soybean meal offers health benefits such as isoflavones and antioxidants as well as benefits with respiratory diseases such as porcine reproductive and respiratory syndrome (PRRS).

One of several ingredients that compete with the inclusion of soybean meal in pig diets is dried distillers grains with solubles (DDGS).

“With DDGS, we typically see more variable responses because of the quality differences depending on which plant it comes from,” said Dr. van Heugten. “At very high levels, we often see a reduction in performance especially with feed intake which can have negative consequences on pig performance, especially in the summer months when feed intake is already low and gaining weight is at a premium to get them to market.”

Over the last few decades, the industry has also seen the increased inclusion of crystalline amino acids in pig diets.

“We started with lysine at about 3 lbs. per ton in the diet, and then we added methionine and threonine to go to 6 to 8 lbs. per ton,” he said. “Now we have tryptophan, isoleucine and valine and can go to 12 to 15 lbs. per ton. All of these, when price competitive, are formulated into the diet and are displacing soybean meal which also removes the potential health benefits that soybean meal provides.”
