This year, Bio-Gel®—a bio-based polymer fertilizer coating—was put to the test in corn and alfalfa fields across Southeastern Minnesota and the Central Midwest.
The goal? To measure how Bio-Gel® performs across different soil types and cropping systems.
The results? Bio-Gel® consistently improved nutrient delivery, reduced salt stress, and boosted forage yield and quality, especially in soils challenged by compaction or inconsistent moisture.
Biggest Gains in Heavy Soils
Fields with Greenbush silt loam and Webster clay loam, soils notorious for poor drainage, saw the strongest responses. In Webster clay loam, soil moisture rose 6%, alfalfa dry matter yield climbed 26%, and forage digestibility improved 20%. Corn in these soils also showed better nitrogen uptake and early vigor.
Higher Forage Value
Alfalfa grown with Bio-Gel delivered stronger feed quality: crude protein increased up to 7%, with higher levels of key amino acids like lysine (+7%) and leucine (+8%). Mineral content, including calcium, boron, and zinc, also improved, reducing the need for costly supplements.
Moisture and Salt Management
Bio-Gel reduced sodium levels by 10% while improving osmotic regulation, helping plants manage salt stress and water balance. This proved valuable in fields prone to salt buildup or moisture swings.
Works Across Farming Systems
In conventional systems, Bio-Gel drove quicker responses, including higher soil temperatures (+6%) and leaf nitrogen (+2%). In organic systems, where nutrients release more slowly, the benefits were steadier but still clear—particularly in moisture retention and long-term soil health.
The Bottom Line
From improving yield to enhancing forage value, Bio-Gel® is proving to be more than a coating. It’s a performance tool that helps crops thrive in tough soil conditions. Bio-Gel® is a win for both soil health and livestock nutrition.
