Faced with environmental, food and energy issues, profound paradigm shifts must be initiated by societies.
The vulnerability of systems and resources requires the implementation of management methods that guarantee their sustainability. UniLaSalle is committed, through the activities of its AGHYLE research unit, to participating in the understanding of the biological and physico-chemical phenomena that impact the critical zone sphere.
The ecosystems that make up this zone provide many services to society: food and non-food biomass production, nutrient cycling and availability, water protection and remediation, soil erosion control, climate change mitigation, biodiversity conservation, etc.
However, these ecosystems are subject to strong anthropogenic pressures that can affect their functioning and production.

The scientific project
History of the unit
Created in 2016 following the Esitpa-LaSalle Beauvais merger and accredited by the HCERES in 2017, the AGHYLE inter-site unit (Agro-ecology, Hydrogeochemistry, Environments & Resources, UP 2018.C101 of the Ministry in charge of Agriculture) was built by capitalizing on its historical assets: its privileged links with, on the one hand, the National Network of the Chambers of Agriculture (APCA) and, on the other hand, the worldwide network of LaSallian universities.
This context has enabled the development of synergies between complementary skills and the capitalization of cutting-edge technological resources available to the teams, such as the Hydrogeology platform, which allows the study of the circulation of water flows and the transfer of pollutants in the soil, and the Normand Serre Experimental Station, which groups together laboratories and confined greenhouses for the study of the processes involved in plant nutrition and health.
The Unit, directed by Isabelle GATTIN and co-directed by Stéphane FIRMIN, now gathers about twenty permanent scientists and about fifteen PhD students around agro-ecology.
The AGHYLE Unit
The Unit aims to contribute to the understanding of the interrelationships between management practices, soil condition and plant diversity and to identify the consequences of these interactions on the dynamics of elements and plant quality through 3 research axes
1 - mechanisms of soil/plant/land organisms interactions
2 - processes of element availability in the rock-water-soil-plant continuum
3 - quantification and modeling of transfers
The challenge of the research work is to optimize the management of agro & eco-systems for their sustainability.
The knowledge acquired within these axes and their synergies accompany and create innovation in the fields of plant production for integrated crop protection, preservation of soil and water resources, and thus promote agro-ecological practices and ecological engineering. The numerous aims concern the identification and evaluation of biocontrol and/or fertilizing solutions, the development of new methods/standards for the identification of indicators or the construction of decision support tools for the evaluation of innovative practices.

The Condorcet federative research structure (SFR) was created through a synergy between researchers from the laboratories of the Universities of Reims Champagne-Ardenne and Amiens Picardie Jules Verne. It is based on the strong desire of researchers from both regions to pool their skills and expertise in the field of agri-resource development, the environment and sustainable development.
The SFR Condorcet, recognized by the CNRS since January 1, 2012, currently brings together 24 public and private research structures. More than 600 research professionals work in this federation. It includes other regional institutions such as UniLaSalle, ESCOM, UTC, Agro Paris Tech, CentraleSupélec, as well as non-academic partners such as ARD (Agro-Industrie Recherches et Développements, in Pomacle) and Extractis (former Centre de Valorisation des Glucides, in Dury). It also extends to the Hauts-de-France region through the "Charles Viollette" regional research institute in agri-food and biotechnology and the Environmental Chemistry and Life Interactions Unit of the Université du Littoral Côte d'Opale.
The objective of the SFR Condorcet is to federate the research activities of the laboratories, whether this research is public or private. To do so, the SFR Condorcet has set as its main objective to help laboratories to develop new collaborative projects.
AGHYLE is part of the actions of the Axis 1 of the SFR CONDORCET: "Sustainable production of plant biomass and environmental insertions".
This Federative Structure labeled in 2017 by the Ministry of Higher Education and Research co-founded and co-directed by UniLaSalle (Karine LAVAL) aims to federate the disciplines in plant sciences and agronomy in Normandy to generate new collaborations based on unique and complementary skills, strengthen the national and international legibility of the constituent units and increase the attractiveness of the Normandy territory.
The skills of SFR NORWAY's researchers cover disciplinary fields ranging from plant biology to agronomy, including microbiology, biochemistry, physico-chemistry, ecology and economics. The SFR promotes multidisciplinary research in the field of agro-ecology, nutrition and plant health, focusing its activities on plant-soil-microorganism relationships and relies on the technology of the Station Expérimentale Normand Serre for the realization of its research programs.
5 research units on the Norman territory, including the AGHYLE unit on the Rouen campus, that is to say about a hundred researchers, PhD students and post-docs are thus federated with the following objectives:
- the development of innovative agronomic solutions that promote the economy of inputs and the use of biocontrol products and methods for integrated crop protection (MAA's Ecophyto Et Produire autrement plans)
- development of agronomic resources
While promoting scientific collaborations with academic and socio-economic partners.
Each year, SFR communicates on the programs supported within its teams through a dedicated Scientific Day: The SFR Normandie Végétale Day organized in turn by the University of Rouen, the University of Caen and UniLaSalle.
This RMT will take over from the Fertilization and Environment RMT. Plant nutrition and crop production are at the heart of the issue of sustainable agricultural production: establishing strategies that allow the plant to use the nutrients available in the agrosystem, complemented with the right dose of inputs, minimizing their use and impact on the environment.
Nevertheless, these issues are being profoundly revisited in the light of changes in practices and cropping systems. These changes are induced by (i) the shift of agro-ecology to respond to the challenges of climate change, biodiversity conservation, and environmental and food quality, opening a growing place for organic agriculture, conservation agriculture, agroforestry, (ii) the voluntary transition to the circular economy to adapt to the scarcity of resources, leading to a wider mobilization of quality fertilizing materials from renewable resources, better use of nutrients from waste of increasingly varied origins and (iii) diversification of the methods of production and recovery of organic residues (various composts, methanization digestates) or minerals ("waste-sourced" derivatives): struvite, biochar, etc.) under the best agronomic, health and environmental conditions.
The RMT BOUCLAGE will conduct interdisciplinary work (notably in the fields of agronomy, agro-ecology and economics) aimed at 1) understanding the determinants of the practices, alone and in combination, mobilized for the management of biogeochemical cycles and crop fertilization and in a systemic and anticipatory approach, and 2) controlling their environmental and health impacts.
The RMT PHYTOSTIM took over from the RMT ELICITRA in 2020. This RMT is interested in phytostimulation in general, and will lead at the same time, scientific advances, methodological progress and integration of solutions in cropping systems. AGHYLE Rouen is a partner of this network.
The AGHYLE team aims to share with the RMT research work in the field of plant protection in a context of agro-ecological transition through the stimulation of the plant immune system and development, which is one of the research axes of the Unit.
