Prerequisites
A course introducing soil science
Main themes
· Soil-plant interactions : functioning of cultivated soils, determinants of soil fertility, dynamics of soil exploration by root systems, rhizospheric processes
· Biogeochemical cyles and processes : action of soil organisms (plants and animals) on the nutrient cycles, ecological requirements and biogeochemical action of organisms, soil degradation, modifications of biological properties
- Fertiliser science : estimation of crop demand, use of mineral and organic fertilisers, recent technological advances
· Biogeochemical cyles and processes : action of soil organisms (plants and animals) on the nutrient cycles, ecological requirements and biogeochemical action of organisms, soil degradation, modifications of biological properties
- Fertiliser science : estimation of crop demand, use of mineral and organic fertilisers, recent technological advances
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.
