Potato Autumn Exchange 2025: Record Harvest and Transport Challenges Dominate German Potato Trade Talks

Rising transport costs, CO₂ pricing, and strained infrastructure: these were the central topics at the 72nd Potato Autumn Exchange hosted by the German Potato Trade Association (DKHV), which took place on September 23 in Hamburg.

Around 130 guests from the trade, logistics, science, and politics came together to discuss how the industry can secure its supply chains in an increasingly challenging environment — in a year when Europe is expecting a record potato harvest.

Market Dynamics Shaped by the Expected Large Harvest

In his opening speech, DKHV President Thomas Herkenrath highlighted the unique circumstances of this season. Thanks to favorable growing conditions and an expansion of cultivation areas, a large potato harvest is expected in Germany and across Europe this year. 

While a significant portion of table and processing potatoes is secured through contracts, freely traded and speculative volumes are coming under pressure due to weaker international demand. At the same time, a substantial part of the main harvest remains in the fields, facing weather risks that could decisively affect yields, quality, and market development.

Herkenrath emphasized that the current situation reflects a normal market cycle.

Thomas Herkenrath, President of the German Potato Trade Association (DKHV):

"Following last year’s high prices, more land was planted, and additional volumes were produced without concrete agreements with buyers."

DKHV President Thomas Herkenrath delivering his opening address, highlighting the prospects of a record potato harvest and challenges for transport logistics.

He added that the potato trade must now ensure that any surplus is used sensibly, thereby maintaining stability throughout the value chain.

Thomas Herkenrath:

"Consumers benefit from good quality at attractive prices, and at the same time, we are working to ensure sustainable returns for farmers. The sector has successfully navigated similar situations in the past, and I am confident that we will succeed again this year."

Political Frameworks as a Key Factor

Against this backdrop, Herkenrath stressed the importance of reliable political and regulatory conditions for the competitiveness of the sector.

Thomas Herkenrath:

"Especially with this year’s large harvest, it becomes clear how vital functioning transport routes are."

Wiechert Steert of BALD Logistics highlighted that lighter trailers could significantly improve transport efficiency, which is crucial when large harvest volumes need to be moved quickly and reliably. He also pointed to differences across Europe.

Wiechert Steert, Representative of BALD Logistics:

"While many European countries allow 44-ton trucks, Germany still maintains a 40-ton limit."

Harmonizing these regulations would provide considerable relief for logistics operations, he added.

Scientific Insights

Prof. Dr. Hanno Friedrich of Kühne Logistics University in Hamburg offered a scientific perspective on these developments. He explained that due to CO₂ pricing and the upcoming EU Emissions Trading System (EU-ETS 2), transport costs are expected to continue rising.

This impact will be especially pronounced for traditional diesel trucks, which still handle the majority of potato transport today. For an industry that depends on flexible and seasonal logistics solutions, this poses a particular challenge — especially in years with record harvests.

Opportunities and Challenges

In addition to identifying risks, participants also discussed potential solutions, including alternative drive systems, digital planning tools, and intermodal transport concepts. 

It became clear that there is strong interest in innovative ideas, and the potato industry is open to adopting new approaches, such as more efficient route planning.

Thomas Herkenrath:

"It’s about becoming even more competitive — not only in transport but across the entire value chain. This can only be achieved together: within the association, beyond association borders, with customers and farmers, as well as with the freight forwarders and logistics companies that move our potatoes every day."

Tradition Meets the Future

The 72nd International Potato Autumn Exchange concluded with open discussions and networking. The event remains a key fixture on the industry calendar, serving as a platform where tradition and the future of the potato sector come together.
