Terres Inovia is releasing its latest results from the Syppre Berry and Syppre Picardie platforms.
Syppre Berry - Another historically difficult year for field crops in the Berry region
Each year, researchers involved in the Syppre project review the results and lessons learned from the previous growing season, as well as conduct a multi-year analysis covering the entire duration of the experiment. This year, it is the turn of the Berry platform.
The 2024–2025 growing season was another historically difficult year for field crops in the region, severely impacting both systems. As in the previous season, it is characterized by an exceptionally rainy fall, which severely affects the establishment of fall crops, as well as a marked drought beginning in May, which hindered the late-season growth of fall crops and significantly impacted spring crops.
Consequently, the economic performance of farms in the region has deteriorated significantly. In this challenging climatic and economic context, it is noteworthy that the innovative system proves to be slightly more resilient than the control system of rapeseed-wheat-barley, as was the case in 2024.

Syppre Berry - The Benefits of Diversification for Improving Barley Yields
Diversifying crop rotations significantly improves winter barley performance. In this innovative system, foxtail weed pressure is much lower than in the rapeseed–wheat–barley rotation, leading to higher yields and greater economic margins. These results confirm the benefits of adjusting the timing of barley planting and introducing spring crops such as sunflowers to ensure a stable harvest.

Syppre Picardie - A Decade of Monitoring Changes in Carbon Stocks
As it enters its 10th year, the Syppre Picardie platform has reached a key milestone with the completion of measurements of organic carbon and nitrogen stocks in the soil. These analyses, based on 270 samples and conducted on the same plots as in 2016 as part of the AMG-Lab project (with financial support from Ademe), will make it possible for the first time to assess changes in these stocks and compare the results with simulations carried out to date.
