Cadiz will host the XX SEFIN Congress and III BeMiPlant from May 26 to 28, 2026
Description
Cádiz will be the meeting point for the scientific community dedicated to nitrogen fixation and, increasingly, to a broader field of research: beneficial interactions between plants and microorganisms . From May 26 to 28, 2026 , the Andalusian city will host the XX Congress of the Spanish Society for Nitrogen Fixation (SEFIN) , which this year also coincides with the third edition of BeMiPlant (Beneficial Plant–Microbe Interactions) .
In recent years, the congress's focus has evolved from the study of symbiotic nitrogen fixation to a more integrative framework that includes multiple plant-microorganism relationships with an impact on crop productivity, sustainability, and resilience. This dual dimension (SEFIN + BeMiPlant) expands opportunities for collaboration, knowledge transfer, and the generation of new knowledge.
Sending communications and registration dates (updated)
The deadline for submitting communications is March 31, 2026 , and the official language of the congress is English , so abstracts must be submitted in this language (one communication per registration).
Regarding registration , the congress website lists the updated dates:
- Early registration: until March 31, 2026
- Late registration: until April 15, 2026
In addition, different fees are considered for members and non-members, as well as a junior modality (predoctoral and postdoctoral with less than 5 years since thesis defense), and the "late" fee implies an increase compared to the early one.
The organization has also indicated that SEFIN Junior members can opt for payment by bank transfer , leaving the payment pending until the scholarship resolution; those who are not beneficiaries must complete the transfer after said resolution.
Venue and logistical recommendations
The congress will take place at two venues in Cadiz:
- Constitution of 1812 Building (Former La Bomba Barracks) , Paseo Carlos III, No. 3
- Faculty of Philosophy and Letters , Av. Dr. Gómez Ulla, 1
Given the tourist nature of the city, the organization recommends booking accommodation in advance .
