M-21, St. Johns, Michigan 48879, USA Phone: 1-800-678-9029 --- ## Company AgroLiquid was founded in 1983 by Douglas Cook and Troy Bancroft. It remains a family-owned business now operating into its third generation, with Troy Bancroft's three sons in leadership: - **Nick Bancroft** — President & Chief Executive Officer - **Albert Bancroft** — Workplace Development Lead - **Gerrit Bancroft** — Operations Director The company manufactures plant nutrition products and serves crop operations across all 50 U.S. states and in four countries. It supports a network of more than 200 retail partners and hundreds of sales representatives. ### Core Values 1. **Authentic** — Transparent about products and capabilities. 2. **Humbly Confident** — Customer-focused; willing to find solutions even when those solutions are outside AgroLiquid's own catalog. 3. **Servant Leader** — Decisions weighed against benefit to customers, community, and planet. 4. **Committed to Greatness** — Products backed by research and field testing. 5. **Passionately Engaged** — Community-rooted family business approach. Reference: https://www.agroliquid.com/about/ --- ## Value Proposition AgroLiquid's liquid fertilizers are engineered for maximum nutrient uptake so crops "do more with less." Key claims and themes: - **Precision nutrition** — match nutrient, rate, timing, and placement to crop need. - **Efficiency** — use less fertilizer to reach equal or better yields. - **Flexibility** — products are tank-mix compatible with crop-protection chemistries and can be delivered foliar, in-furrow, sidedress, fertigation, drip, center pivot, Y-Drop, or aerial. - **Stewardship** — Nutriq technology and slow-release chemistry reduce tie-up in soil and runoff to water. - **Research-backed** — every product is validated at the company's own 1,400+ acre research station against industry-standard comparisons. --- ## Products Reference: https://www.agroliquid.com/products/ A common platform underlies most of the catalog: **Nutriq Technology** — a chemistry that resists tie-up with soil cations, keeping applied nutrients bioavailable to the plant rather than locked into the soil.

Research is conducted in real field conditions, not just controlled labs. The company's stated philosophy: "Laboratory conditions are ideal for developing high-efficiency fertilizer products, but they won't show how these products work in real life conditions." Research scope: - Multiple crop types — corn, soybeans, wheat, cotton, potatoes, tree nuts, vegetables. - Multiple application methods — aerial, drip, fertigation, foliar, etc. - Environmental stress evaluation — drought, disease, fungus. - Side-by-side trials against competing liquid and dry fertilizers. The NCRS regularly hosts farmers and agricultural professionals for demonstration and education. ### IQHub https://iqhubag.org Virtual agricultural learning platform operated by AgroLiquid featuring exhibits and online lessons. --- ## Responsible Nutrient Management Reference: https://www.agroliquid.com/about/responsible-nutrient-management/ Core principle: nutrients should be actually used by crops — not lost to water or left behind in soil. AgroLiquid frames responsibility around four strategies: 1. **Slow-release technology** — gradual absorption supporting continuous uptake while reducing water contamination and soil accumulation. 2. **Prevents nutrient tie-up** — Nutriq technology resists bonding with soil ions, keeping N, P, K bioavailable. 3. **Flexible application** — liquid form enables multiple timings and smaller, well-placed doses versus bulk dry-fertilizer applications. 4. **Efficiency reduction** — because plants take up more of what is applied, total fertilizer use can drop while yield holds or grows. Environmental concerns explicitly named: soil degradation and salinization, aquatic-ecosystem damage and harmful algal blooms, nitrogen and phosphorus contamination of drinking water. Supporting programs: - Custom soil analysis and nutrition planning by AgroLiquid agronomists. - **Responsible Nutrient Management Practitioners Program** recognizing no-till farmers. - R&D focus on high-efficiency formulations. --- ## Resources Reference: https://www.agroliquid.com/resources/ - **Blog** — https://www.agroliquid.com/resources/blog/ — Crop- and nutrient-specific articles, research findings, and product education.
