What We Stand For

It’s time for us to demand more from our plants and less from our planet.

At Verdesian Life Sciences, we enable a more sustainable, profitable future for farmers through nutrient use efficiency. We firmly believe that sustainability and profitability are not mutually exclusive, and our technologies are designed to protect the environment while helping farmers outdo what they’ve always done.

Everything we do at Verdesian has the best, long-term interest of the grower in mind. Our portfolio of products and technologies enhance nutrient uptake, reduce nutrient losses to the environment and improve yield potential.

We are committed to helping farmers maintain and improve water quality and soil health, and are adamant in our belief that we can do this together. Sustainability is a global movement, but big changes start with small actions. One practice, one tool or one new agronomic opportunity can improve nutrient efficiency, increase yield and dial up profits.

We Are The Nutrient Use Efficiency People

Established in 2012, Verdesian Life Sciences offers farmers and growers the biological, nutritional, seed treatment and inoculant technologies that maximize performance on high-value row crops and specialty crops, as well as turf and ornamental plants. With a diverse product portfolio of over 300 patent properties, our solutions are designed to enhance crop uptake, reduce nutrient losses to the environment, and improve yields for all growers. We are committed to the research and development of nutrient use efficiency technologies that make farming more efficient, more sustainable, and more profitable.

Our technologies are supported by exclusive licenses and research partnerships with leading global research institutions and universities, including Los Alamos National Laboratory, University of California Riverside, University of Chicago, and Pacific Northwest National Laboratory. As a 4R Nutrient Stewardship Partner, we are committed to researching and developing environmentally sustainable products.

Investing in both science and people, we develop and retain the best and brightest talent in the industry to bring our technologies to the grower.

Headquartered in Cary, North Carolina, we have production and manufacturing facilities strategically located in Pasco, Washington; Kentland, Indiana; Cape Girardeau, Missouri; South Salt Lake City, Utah; and North Lima, Ohio.

What We Believe In

As the Nutrient Use Efficiency People, Verdesian Life Sciences is committed to making farmers more profitable through sustainable and responsible means. However, those two words are not lip service; we live by them. Our nutrient use efficiency technologies are designed to protect the environment while helping farmers outdo what they’ve always done. Sustainably.

Just as important is our commitment to improving the lives of those around us. Agriculture is inextricably tied to every fiber of life, and so should everything we do. It is our duty to do what we can to improve the lives of those around us.

Verdesian and the IAWA

As a leader in Iowa agriculture, Dave Schwartz is passionate about sustainable farming, first as a grower himself, but also as a VP of Sales at Verdesian Life Sciences. Schwartz’s involvement on behalf of Verdesian with the Iowa Agriculture Water Alliance (IAWA) is a testament to that dedication.

The IAWA is increasing the pace and scale of farmer-led efforts to improve water quality in Iowa. Founded in 2014 by Iowa Corn, Iowa Soybean Association and the Iowa Pork Producers Association, IAWA is building public-private partnerships focused on implementing water quality solutions. Verdesian Life Sciences is a proud member of the IAWA Business Council, of which Schwartz has served as chairperson.


Doing what’s right doesn’t mean doing what’s just right for the bottom line. We also are committed to doing what’s right for people. Our most important asset is our people. That belief extends beyond just our own employees but also to our retail partners and our grower customers. But that philosophy also conveys just as equally to our neighbors and to strangers. At Verdesian Life Sciences, we are committed to making the world a better place for the great people that inhabit it.

Nebraska Strong

When floods ravaged parts of the Midwest during the spring of 2019, Verdesian Life Sciences employees decided to act. Over the course of several weeks in March and April 2019, members of Verdesian’s sales, technical services, marketing, operations (and more) departments crisscrossed across Nebraska cooking burgers and brats, delivering meals and hope to farmers and retailers impacted by floods that washed out roads and bridges, not to mention fields and crops. The group of Verdesian representatives fed and fellowshipped in places like Fullerton, Oakland, Tekahmah, West Point and more. “The agricultural industry is a family – it’s close-knit,” said Scott Ahrenholtz. “We are all one family and when they are in need we are here to help.”

Habitat for Humanity

As the son of a builder, home construction is in the blood of Kenneth Avery, CEO, Verdesian Life Sciences. Helping to build homes for those less fortunate is part of his DNA – and it has become a major part of the DNA at Verdesian, as well.

For 30 years, Avery has volunteered for Habitat for Humanity. He currently serves on the Board of the Wake County (NC) Habitat for Humanity. During his time in Cary, Avery has inspired his Verdesian colleagues to take time out at least once a year for a building project.

“I am a firm believer in the adage that we leave things better than we found them, and our involvement with Habitat affirms that. I am very proud of Verdesian’s commitment to giving back to those who just need a little bit of help.”

Verdesian Gives Back

In July 2018, Verdesian Life Sciences celebrated the winners of its Performance Guarantee Giveaway in two small farming communities in the Midwest. In Stitzer, Wisconsin, cattle rancher and grower Marland Bode and his wife LeeAnn received a brand-new Ford F-150, while in Ethan, South Dakota, ag retailer CHS Farmers Alliance Co-op won $30,000 to spend on local community causes.

The monetary prize will go far in Ethan, a 329-person town whose wide array of public resources and strong sense of community pride belie its tiny population. CHS Farmers Alliance Co-op manager Mark Endres divided the $30,000 prize between five programs in Ethan: $8,000 to upgrade the baseball diamond park, $10,000 for the public school, $5,000 for the city, $4,000 to complete the American Legion memorial park, and $3,000 to fund children’s art classes and other needed resources at the community center.

“We believe sustainability and profitability go hand-in-hand,” said Dave Schwartz, VP of Sales. “We call ourselves ‘The Nutrient Use Efficiency People™,’ and we’re constantly researching and producing new solutions to help farmers grow more with less inputs.”

Diversity, Equality, Inclusion, and Belonging

At Verdesian, we believe our most important asset is our people. This belief extends beyond our team to our partners, grower customers, neighbors, and communities we serve. Our vision is to leave the world better than we find it by embracing our differences and fostering a diverse and inclusive working environment where we value our team’s backgrounds and experiences.
