Our Story

Field Ag & Co. is an independent agricultural retailer proudly based in Webb, Iowa, serving farmers across northwest Iowa and beyond. Founded in 2024 by Pete Crew and Brian Nash—two Iowa natives with a combined 60+ years of experience in agronomy, finance, and farm operations—we exist for one reason: to help you produce profitable, resilient crops while building long-term soil health.

We don’t just sell crop protection products. We challenge conventional thinking, run on-farm trials, share real-world data, and deliver recommendations that work in our local soils and climate. As a truly manufacturer-agnostic dealer, we source the highest-quality generics and top-tier branded products (including UPL North America’s industry-leading portfolio) so you get proven performance without inflated prices.

Whether you’re looking for cost-effective generic herbicides, biologicals, precision nutrient programs, or the latest soil-health tools, we’re here to be your trusted partner from planting through harvest—and for many seasons to come.
