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.

Main themes
1 Soil forming processes and pedological processes in tropical regions (inter-tropical and Mediterranean areas): alterationcomplex and major constituents, identification of major soil types and their constituents (WRB system).
2 Relations between constituents and properties: analysis of surface properties and charge through the study of permanent and variable charge models; implications for physical and physico-chemical soil properties.
3 Diagnosis of major soil constraints in warm regions: mineral reserves, humus stocks, acidity, salinity, nutrient depletion,mass recovery, compaction, erosion, water availability: derive constraints from the knowledge of constituents-propertiesrelationships.
4 Remediation and management techniques, viewed through some major cropping systems and soil types.

Content
Four topics will be adressed :
Part I ' Soil forming processes and pedological processes in warm regions : use of phase diagrams (stability, solubility), recognition of major soil types via the interpretation of morphological and analytical data of typical soil profiles.
Part II - Relations between constituents and properties: studyof permanent and variable charge models, isoelectric point and point of zero charge, retention of cations and anions, phosphate adsorption, carbon storage, micro-aggregation, implications for physical and physicochemical properties of the soils .
Part III - Diagnosis of major soils in tropical regions: determinants of fertility, estimates of stocks of humus and nutrients, diagnosis of constraints (nutrient depletion, acidity, salinity') and physical degradation (hard setting, compaction, erosion) based on morphological and analytical data.
Part IV - Techniques of remediation and management viewed through some major cropping systems and soil types (case studies)
