What Midwestern Bioag does
Midwestern BioAg is a privately held, biological-farming-focused agricultural inputs and services company headquartered in Blue Mounds, Wisconsin, founded in the early-to-mid 1980s by dairy nutritionist Gary Zimmer. The company designs, manufactures, and distributes a portfolio of proprietary soil health, fertilizer, soil amendment, water efficiency, livestock nutrition, seed, and wildlife products — built around a thesis that improved soil biology drives farm productivity. Its flagship proprietary technologies include the TerraNu® line of carbon-based homogenized granule fertilizers, Bio-Cal® (a multi-source calcium soil amendment), Bio-Gel® (a carbohydrate-based hydrogel for water and nutrient retention), and OrganiCal™ for organic operations, complemented by a WinterKing™ alfalfa seed line, L-CBF liquid fertilizers, and a complete livestock mineral/nutrition range.
The company's business model combines direct-to-grower agronomic consulting (soil testing, plant tissue analysis, forage analysis, and variable-rate fertilizer application using owned spreader carts and floater trucks) with a two-tier channel: a dealer network (which buys at dealer cost and resells with local delivery/application) and an agent network of 1099 commission contractors across the United States and Canada. Pricing is quote-based and not publicly disclosed, with a tiered Field Rebate Program (Gold/Silver/Bronze at $2,000/$1,500/$750) used to drive multi-year on-farm trials and yield-data capture. Customer segments span row-crop producers, organic farmers (approximately 30% of the customer base), dairy operations, produce growers, conventional-to-organic transitioners, wildlife food-plot managers, residential homeowners, and increasingly financial institutions/land funds and large food companies seeking supply-chain sustainability. Documented yield and efficiency outcomes — such as 45% nitrogen savings in oats, 0.5–0.7 lbs N/bushel corn versus a 1.2 lbs industry average, up to 17% corn yield gains with Bio-Gel, and up to $12/acre ROI with TerraNu — form the technical backbone of its value proposition.
The company has raised approximately $48 million in disclosed funding across 2015–2018, with the largest round ($21.3M, November 2016) led by S2G Investments alongside Bison Capital, Franciscan Sisters of Mary, Madison Bay Capital Partners, and the McKnight Foundation. In January 2026, Brad Griffith was appointed CEO following an October 2025 'new era of growth and partnership' announcement, suggesting the company is positioning for an accelerated growth and partnership-driven scaling phase.

Midwestern Bioag product offering
Product offeringCore offering
Midwestern BioAg develops, manufactures, and sells proprietary biological farming inputs—including carbon-based TerraNu® fertilizers, Bio-Cal® calcium soil amendments, Bio-Gel® hydrogel water-efficiency products, livestock nutrition minerals, seeds, and wildlife plot products. The company pairs these products with agronomic consulting, comprehensive soil testing, and variable-rate fertilizer application services for row crop, dairy, organic, and produce growers across the United States and Canada.
Product overview
Midwestern BioAg offers a comprehensive portfolio of biological farming products organized into five main categories: Fertilizers (TerraNu® homogenized carbon-based fertilizers, conventional fertilizers like MAP and Sulfate of Potash, organic fertilizers, and liquid fertilizers including L-CBF line), Soil Amendments (Bio-Cal® conventional calcium amendment and OrganiCal™ organic calcium), Water Efficiency (Bio-Gel® carbohydrate-based hydrogel for water and nutrient retention), Livestock Nutrition (complete mineral and vitamin packages under the 'O' product line, Bio-Vet® probiotics, silage inoculants, and forage supplements), and Wildlife/Residential products. The core platform is built on the company's 40-year legacy in biological farming, with TerraNu® products representing the flagship homogenized granule technology that combines carbon with micronutrients. Products are designed to work as an integrated system—fertilizers feed both plants and soil biology, soil amendments correct deficiencies, and water efficiency products retain nutrients in the root zone. The company also offers seed products (WinterKing™ alfalfa and HQF pasture blends) and programs for dairy, produce, and row crop operations.
