Supplementary skills: soil science, biosphere engineering, systems analysis
Plant culture practices (3 credits)
Temperate major crops. Soil evolution and crop evolution through the seasons. Agricultural works (soil management, seeding, fertilizing, weeding, crop protection, harvest). Weed identification in major crops at a young stage and specific identification keys.
Mechanization (2 credits)
The tractor. Soil management. Seeder. Manure spreader. Soil pulverizer. Harvest machines.
Precision agriculture (1 credit).
The approach of precision agriculture. Techniques (GIS, GPS, captors). Application (soil, plant pathology, water). Success and adoption requirements.
a. Contribution of the activity with regards to the referential of leaning outcomes
Control a pool of scientific knowledge in crop production (M1.1, M1.2, M2.2)
Control a pool of knowledge in the fied of bioengineering through a quantitative approach, facing a complex problem of agronomy at the scales of the plant and the field (M2.4)
Apply a rigorous, innovative and systematic scientific approach in order to deepen a research problem in the field of crop production (M3.3, M3.4)
b . Specific formulation for this activity AA program (maximum 10)
At the end of this activity, the student will be able to :
- Define the agricultural practices in major crops and justify them on the basis of plant physiology and ecophysiology
- argue a crop protection method according to environmental and physiological constraints of the crop
- criticize the adequacy of plant culture practices in the global frame of the production system
- describe the functions and functionning of the main components of the farm tractor
- describe the mode of action of the main working soil tools and be able to justify their choic according to the objectives
- describe the main components and functionning of seeders, manure spreaders, soil pulverizers and harvest machines
- document and discuss the variation sources inside a field plot
- identify situations in which precision agriculture make sense

Introduction : definition and motivation
Basic components
Technologies : computer, geographic information system, GPS, captors and control systems
Making the difference between «precision agriculture » and « precision of agriculture »
Approch of precision agriculture: variabilty assessment (types of variability, quantifying methods and techniques, modelling), variability management (pH, main nutrient, weeds, pathogens, pests, water and culture management)
Evaluation: economic profitability, environmental impact, technology transfer (innovation)
