Potato Sustainability Alliance welcomes new member companies and grower associates

The Potato Sustainability Alliance (PSA) has welcomed three new members to its organization in the first quarter of 2024. Soil Health Institute becomes the fourth Environmental NGO to join PSA, while Walther Farms and DeGroot’s Vegetable Farms join as Grower Associates, the newest member category offered by PSA. 

PSA is an inclusive, pre-competitive collaboration of all players in the potato value chain. Over the past 12 years, PSA and its members have worked to define, measure, and advance potato sustainability by using robust metrics to drive improvements in productivity and profitability. Efforts are focused on protecting the environment and streamlining how farm-level data is collected and made available to end users. 

A new Grower Associate category was added this year to address the unique needs and important contributions from potato growers. For growers that see value in demonstrating their sustainability commitment to their customers, PSA offers an opportunity to connect with an international organization focused on potato sustainability. 

“At every stage of the value chain, from growers to retailers, sustainability issues continue to grow in importance. Our job at PSA is to help the potato industry work together, across business lines, to proactively develop comprehensive sustainability guidelines,” said John Mesko, PSA CEO. “Every time we get to welcome a new member company or grower, our organizational reach extends further and we are able to be even more effective in our mission to advance potato sustainability.”

Companies interested in learning more about the benefits of PSA membership are invited to contact John Mesko at or visit for more information.
