More Info


Valley Agronomics provides a wide variety of seeds including grass, corn, alfalfa, grains, & cover crops. Our plant in Arco, Idaho cleans and treats seed, giving us the ability to contract seed production that is unique to our coop members’ needs.

What we really pride ourselves in doing is not just selling you seed but selling you a seed that matches your needs. When our agronomists help you in choosing your seed varieties, besides the quality of the seed genetics, they look at all the factors that will affect the production of that seed: your management style, your soils, fertility, and your water situation.

Crop Nutrition

“Your fertilizer is the same as the other guys’, right?”, is a question we’re often asked. Nothing could be further from the truth! At Valley Ag, we bring new and innovative products to our coop members. We were the first to bring in a competively priced nitrogen, phosphate, sulfur, & zinc (NPSZ) product.

The innovation doesn’t end with our dry products either, we are constantly looking for new ways to improve our liquid fertilizers also. Whether it’s building our biological package with Pharmgrade, teaming up with Actagro to provide Organic Acid technology, or delaying the tie up of liquid phosphate by adding Magnet. At Valley Ag, we are always looking for the next great solution that our coop members are seeking.

Adjuvants & Crop Protection


Through our relationship with Winfield United, we offer adjuvants that are far superior to our competitors. Winfield employees an entire team whose only focus is making and improving adjuvants. WinField United Product and Market Development Manager, Dr. Eric Spandl, says, “Our Spray Analysis System allows us to capture data more rapidly than other systems, which spurs quicker and more precise product development.”

How effective are Winfield United adjuvants? Just ask any applicator that has used “lock” products what they think! Clay from Red Baron Ag says, “We test Winfield United’s drift deposition aid products every year, each time Winfield United’s ‘lock’ products are the best out there.”

Herbicides, Insecticides, & Fungicides

We have the same approach to pesticides that we have with all our products: provide the best and then look for ways to make them better. We do this in many different ways, with an adjuvant from Winfield United, looking for tank mix partners that will create synergies, or looking for ways to precisely apply the chemical only to portions of the field that need it.

As with everything that we do, coop members purchase pesticides from us because, despite the fact the product may be the same thing as the other guys, they know with Valley Ag we have the tools to help the pesticides perform better than our competitors.
