We are looking for a Researcher in Plant Nutrition and Fertigation to join the Efficient Use of Water in Agriculture Program team, based in Lleida. We offer the opportunity to be part of an organization with a dynamic, collaborative work environment focused on professional development.

The successful candidate will lead and contribute to competitive research projects and collaborative contracts focused on sustainable water and nutrient management in agricultural systems. The research activities will address the interactions between irrigation, plant nutrition, soil management and crop performance. The position encompasses research on irrigation and fertigation management, nutrient cycling, dynamics in soil-plant systems, and the process governing nutrient transport and nitrate leaching under different irrigation regimes.

Emphasis is placed on applied research on these topics and transfer of the outcomes to the agricultural sector.

Head of the Program: Dr Joaquim Bellvert

Program’s key researcher/s for this position: Dr Jaume Casadesús & Dr Víctor Blanco.

Tasks and Responsibilities:

- To lead and contribute to the research line on sustainable water and nutrient management in agricultural systems, addressing the interactions between irrigation, fertilization, soil processes and crop performance. The research activities will include the development and evaluation of strategies to improve irrigation and fertilization efficiency, including fertigation management, nutrient application strategies, irrigation system performance, and the sustainable use of water and nutrient resources.
- To perform research on soil–plant–water–nutrient interactions and the processes controlling water and nutrient dynamics in agricultural systems, including nutrient mobility and availability, nitrate leaching and environmental losses, nutrient cycling processes, and the interaction between irrigation practices, soil properties and crop uptake.
- To develop and apply approaches to assess and optimize water and nutrient use efficiency, including experimental approaches, monitoring strategies, and the use of mechanistic and/or empirical models to evaluate water and solute transport under different soil conditions, irrigation regimes and climate scenarios.
- To contribute to the development and evaluation of innovative fertigation and irrigation management strategies, including the optimization of irrigation scheduling, nutrient delivery systems, and the management of irrigation infrastructure (e.g., irrigation networks, filtration systems and fertigation equipment).
- To participate in research projects and collaborative contracts by planning, implementing and monitoring field and laboratory experiments, analysing results,



contributing to scientific publications, and supporting the transfer of knowledge and technologies to the agricultural sector.
- To contribute to the scientific production of the research and innovation activities of the Program.
- To lead and actively contribute fund rising through the preparation and submission of project proposals for public competitive calls and for contracts with the private sector, as well reporting process, such as writing progress and final reports of research activities.
- To identify opportunities for cutting-edge research and innovation to address strategic priorities of the research program on Efficient Use of Water in Agriculture.
- To contribute to the teamwork and team-spirit in the research program on Efficient Use of Water in Agriculture, fostering collaboration and integration activities.
- To create synergies with other research programs at IRTA.
