SLU Agricultural Long-Term Experiments

Many effects of crops, crop rotations and cropping practices used within agriculture only become visible in the long term. The SLU Agricultural Long-Term Experiments are funded by the Faculty of Natural Resources and Agricultural Sciences at SLU, and the data collected in these constitute a unique and valuable resource for research, education, and professional advice. We welcome researchers to use data from our archived long-term field trials or to take new samples. Information from the experiments may also be useful for advisors and others who are interested in Swedish agriculture.

The GLTEN is network of long-term agricultural experiments and associated researchers. The network spans six continents and represents a range of climates, environments, cropping systems and farming practices. Through the portal you can explore agricultural experiments from around the globe, including information about our trials.
