Deep soil = high water resources
Hilly area = low water resources
La Hourre farmThe rotation of crops set up at La Hourre :
1 short rotation : On deep soils (2 plots)rotation : soya and wheatcrops for human consumption = economic aim
1 long rotation : 3 to 5 yearsLegume species between two crops

lentils)
Straw cereals (winter wheat)
Sunflower
Cereals
