Clermont-Ferrand/Lyon, September 29th, 2026, 07:45 am CEST – AFYREN, a greentech company that provides manufacturers with bio-based and low-carbon products through its unique fermentation technology based on a fully circular model, and Terrial, a leading French company in the field of organic and bio-based fertilizers and a subsidiary of Avril, announce the renewal of their strategic partnership.

Known for its bio-based acids, AFYREN also produces a fertilizer in France that is particularly rich in potassium; this fertilizer is processed and used by Terrial to formulate high-value-added fertilizers under the FORTI K+ brand. It meets the needs of a wide range of crops, particularly for fruit and vegetable farming, vineyards and major crops. FORTI K+ provides a sustainable, local source of potassium. It contributes to greater supply autonomy for agricultural players across various regions of France.

Since 2021, AFYREN has been partnered with Terrial, a major player in organic and sustainable fertilization in France. The AFYREN fertilizer, marketed as part of Terrial’s range of innovative formulations, has been further developed to better meet market needs. Its compaction format is perfectly suited to the various spreading systems found on farms.
