Note from June 29, 2020
Although we do not yet know how long the social distancing related to the Covid-19 pandemic will last, and regardless of the changes that had to be made in the evaluation of the June 2020 session in relation to what is provided for in this learning unit description, new learnig unit evaluation methods may still be adopted by the teachers; details of these methods have been - or will be - communicated to the students by the teachers, as soon as possible.

a. Contribution of this activity to the program learning outcomes M1.2, M1.4, M2.4, M3.1, M4.3, M6.1 b. Learning outcome specifics for this activity At the end of this course, the student is able : · to understand soil-plant interactions at the field scale in order to optimise the management of the cropping system and its impacts on the soil and crop · to understand the dynamics and complexity of soil-plant interactions, with reference to the functioning of cultivated soils and to the strategies of soil exploration and exploitation by plants · to interprete plant responses to its environments and to crop management pratices and the impact of the cropping system on the soil · to consider fertility management in a systems framework respectful of environment, through the adoption of ad hoc crop management practices and the monitoring of the cropping system. |

Content
Table of content
1. Soil-plant interactions
· Properties, heterogeneity, fonctioning and evolution of cultivated soils
· Determinants of soil fertility.
· Notion of soil profile ; evaluation of humus and nutrients content, available soil nutrients , indicators of fertility (definition, monitoring)
· Soil exploration by roots : growth and development of typical crop root systems ; response of root distribution to transient and permanent soil conditions
· Rhizospheric processes : soil-plant interactions at the rhizosphere scale (uptake, acquisition strategies, exsudation) ; complexity and dynamics of these processes
2. Biogeochemical cycles and processes
· The soil biome
· Mycorhizal symbiosis
o Plant ' mycorhizae relations
o The mycorhized root
o Mycorhizal networks
· Biogeochemical cycles
o Nitrogen
o Phosphorus
o Potassium
o Sulfur
o Carbon
3. Fertiliser science
· Estimation of crop nutrient requirements : diagnostic and measurement (trials, soil and plant analyses, indicator species, deficiency symptoms, etc.) ; analytical methods
· Use of mineral and organic fertilisers : fertiliser use in crop management ; consideration of soil properties and wheather data (case studies)
· Recent trends in fertiliser use : delayed fertiliser, organic agriculture, intensive agriculture and environment considerations.
