S.T. Biologicals

What S.T. Biologicals does

S.T. Biologicals is a privately held agricultural inputs and advisory company headquartered in Plymouth, Minnesota, that helps row-crop, livestock, and organic producers in the U.S. Midwest transition to regenerative farming practices. Operationally, the firm combines a small in-house proprietary product line — Attest (copper-based growth nutrient), Attria (foliar micronutrient blend), Boron 10%, and Instill (low-dose copper bactericide/fungicide) — with a curated portfolio of distributed third-party brands covering nanoparticle nutrient delivery (the Aqua-Yield Nano-series), complexed micronutrients (QualiTech QMIN), biologicals (Bioactive / Purple Cow Organics LiquiLife+, Supercharger, Liquid Supercharger), soil amendment (Arizona Agricultural Holding's Calcine), and Actigate-technology inputs from Terramera. The technology layer rests on proprietary copper-delivery systems, nanoliquid carriers that drive chemistry into plant cells via endocytosis, polysaccharide-complexed nutrients, and advanced soil diagnostics (PLFA microbial biomass and Haney tests) that measure microbial diversity beyond conventional NPK analysis.

The business model blends one-time product sales with one-on-one regenerative agriculture mentoring from certified crop and livestock advisors, with pricing set via consultation quote rather than published rate cards. The go-to-market is dual-channel: direct field consultation supported by quote-based contact forms, alongside seven regional distribution partnerships that deliver SKU breadth into both organic and conventional operations. The customer base is exclusively SMB farmers — corn, soybean, small-grain, alfalfa, sugar beet, potato, livestock/dairy, and organic produce producers — with named case-study customers limited to Matt Willenbring and Rutkowski Farms. Corporate structure places ST Biologicals as a subsidiary of Seacole, providing parent-company scale on the back-office and supply side while preserving the small-team advisory identity in front of farmers.

Direct peers

• Indigo Ag: Indigo Ag is a direct peer offering regenerative agriculture products, biologicals, and agronomy services (including the Indigo Carbon program) to row-crop farmers. Both companies combine proprietary biological inputs with farmer advisory services to drive regenerative outcomes.
• Pivot Bio: Pivot Bio is a direct peer developing microbial nitrogen-fixing crop nutrition products for row-crop farmers. It competes in the biologicals/regenerative input space that ST Biologicals addresses through its BioActive and Aqua-Yield distributed lines.
• Advancing Eco Agriculture (AEA): AEA is a direct peer providing regenerative agriculture consulting, soil testing, and crop nutrition products to conventional and organic growers. Both companies sell biological/foliar inputs and pair them with one-on-one agronomic mentoring.
• Sound Agriculture: Sound Agriculture offers biological nutrient efficiency products for row crops and works with agronomy partners. It competes head-to-head with ST Biologicals' biological/distributed nutrient portfolio.

Emerging players

• AgBiome: AgBiome develops biological crop protection products (e.g., Howler fungicide) and is an emerging player in the agricultural biologicals space. It overlaps with ST Biologicals' biological and fungicide offerings (e.g., Instill).
• Biome Makers: Biome Makers provides BeCrop soil microbiome analysis (akin to ST Biologicals' PLFA testing). Both companies use advanced soil biology tests to support regenerative agriculture recommendations.
• MyLand Company: MyLand provides soil health services and microbial delivery systems to farmers. It is an emerging player in regenerative agriculture services with overlapping biological/soil-health focus.

Others

• Terramera: Terramera is both a partner and adjacent player developing the Actigate technology platform for crop inputs and biopesticides. As a partner, it is comparable but does not directly compete in agronomy consulting.

Broad incumbents

• General Mills (Regenerative Agriculture): General Mills has committed to advancing regenerative agriculture on one million acres by 2030 and is a downstream buyer of regen outcomes. It is a broad incumbent that drives market demand for ST Biologicals' offerings.
• Cargill (RegenConnect): Cargill's RegenConnect program incentivizes farmers to adopt regenerative practices and is a broad incumbent shaping demand for ST Biologicals' services. Comparable as a downstream buyer of regenerative outcomes rather than a direct competitor.
