Preserving environment, maintening food quality and managing energy are major challenges for our societies.

The vulnerability of ecosystems and resources requires the implementation of management methods guaranteeing their sustainability. UniLaSalle undertakes through the activities of its AGHYLE research unit to participate in the understanding of biological and physicochemical phenomena that impact the sphere of the "critical zone".

The ecosystems that compose this specific area provide many services to society: food production and non-food biomass production, cycle and availability nutrients, protection and remediation of water, protection against soil erosion, climate change mitigation, biodiversity conservation, etc.

However, these ecosystems are subject to strong human activities pressures which can affect their functioning and their production.

AGHYLE scientific project

The AGHYLE Unit

The AGHYLE Unit, headed by Isabelle GATTIN and co-led by Stéphane FIRMIN, brings together around twenty five permanent scientists around fifteen doctoral students on agroecology questioning.

It capitalizes on cutting-edge technological resources, such as the Hydrogeology platform which allows the study of water flows circulation and soil pollutant transfers and the Normand Serre Experimental Station which brings together laboratories and confined greenhouses, to study the processes involved in plant nutrition and health.

The unit aims to contribute to understand the inter-relationships between management practices, soil conditions and plant diversity and to identify the consequences of these interactions on the dynamics of elements and the quality of plants through 3 areas of research:

1 - Mechanisms of soil/plant/telluric organisms interactions

2 - process of elements 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 with a view to their sustainability.

The knowledge acquired within these axes and their synergies support and create innovation in the fields of plant production for the integrated protection of crops, the preservation of soil & water resources, and thus promote agro-ecological practices and ecological engineering.

The numerous purposes to relate to (1) the identification and evaluation of biocontrol and / or fertilizing solutions, (2) the development of new methods / standards for the identification of indicators or (3) the construction of decision support tools development to increase innovative practices in agriculture.

Research activities of AGHYLE are falling within most of the Sustainable Development Goals, as defined by UN, in particular the goal Zero Hunger (n°2) which includes the agroecology approach to enhance crop protection, quality and nutrition, or the goal Life and Land (n°15 which includes the soil biodiversity, the soil pollutions or the elements flows assessment, and the goal Climate Action (n°13) which includes understanding the microorganisms communities in the soil and their realtions with the plants in the climate change adaptation, the soil carbon storage process, and the connection between the soil biodiversity and the resilience state of the ecosystems.

The unit develops, by multidisciplinary approach, ecological, environmental and crop production performance indicators, applied to agroecosystems, in oreder to contribute to agroecological transition.

Research networks

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:

  1. 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)   
  2. 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.

More about SFR Day

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.
