Nitrogen Workshop 2018

Side event

Note: the side event will take place on AGROCAMPUS OUEST (see Access map for location) on Wednesday 27 June 2018.

Nutrient management and decision support systems

For instructions to Authors, see page "Practical information".

The proceedings of the side event are on a USB stick you will receive at your arrival; you ca also download them here:

The side event links the knowledge of processes affecting nitrogen and other nutrient cycling and their use for managing cropping and livestock systems.

It is co-organised by the Fertilisation & Environment technological network (RMT) and the COMIFER association.

The side event focuses on decision-support tools for inorganic and organic crop fertilization, and diagnostic tools for nutrients management. This seminar aims to provide a relatively complete overview of approaches developed in various European countries and beyond, and to discuss them according to several aspects:

  • The conceptual bases of decision-support tools: which approaches are developed in which countries? What operating scales (field, farm, region) do these decision-support tools cover? What farming systems are addressed?
  • What tools are available for joint management of several nutrients?
  • What tools are available for managing multiple nutrients at the same time?
  • National and European regulations: to what extent are they integrated in tools, and how?

These issues will be addressed over the course of a day, on Wednesday 27 June 2018, combining a workshop of tool demonstrations, poster presentations and oral presentations in plenary session.  Proposals for contributions to this side event should be submitted on the common Workshop website, specifying the wish: demonstration of a tool, oral presentation, presentation in the form of a poster.

Gestion des éléments nutritifs et systèmes d'aide à la décision

L'événement organisé en marge du 20ème N workshop à Rennes a pour objectif de faire le lien entre la connaissance des processus affectant les cycles de l’azote et des autres nutriments et leur mobilisation dans la gestion des systèmes arables et d'élevage. Cette manifestation parallèle est organisée par le Réseau Mixte Technologique Fertilisation & Environnement (RMT) et le COMIFER.

Ce séminaire est centré sur les approches et les outils d'aide à la décision pour la fertilisation minérale et organique des cultures, et les outils de diagnostic pour la gestion des éléments nutritifs.

Cette manifestation a pour but de fournir une vue d'ensemble la plus complète possible des approches développées dans les différents pays européens et au-delà, et d'en discuter, avec plusieurs aspects :

  • Bases conceptuelles des outils : quelles approches sont mobilisées dans les différents pays ? Quelles sont les différentes échelles de fonctionnement de ces outils (parcelle, exploitation, territoire) ? Quels sont les systèmes de production concernés ?
  • Quels sont les outils disponibles pour la gestion conjointe des différents nutriments ?
  • Diffusion des outils, et utilisation avec/par les acteurs : quelles méthodes, quels problèmes ?
  • Dans quelle mesure les législations nationales et européennes sont-elles intégrées dans les outils et comment?

Ces questions seront abordées au cours de la journée du mercredi 27 juin 2018, combinant un atelier de démonstration d'outils, des présentations par affiches et des présentations orales en séance plénière. Les propositions de contributions à communication doivent être soumises sur le site Web commun  du 20ème N workshop en précisant le souhait: démonstration d'un outil, présentation orale, et/ou présentation sous forme d'affiche.
