Agronomic summary
Brittany, an oceanic terroir with 305 frost-free days and 1,014 GDD, offers conditions well suited to spring linseed. Acidic silt-loam soils (pH 5.5) require prior liming but otherwise suit the crop perfectly. Galaad, LS Kaolin and LS Riviera can diversify rotations dominated by maize and winter cereals, providing a low nitrogen-demand previous crop. Cool summer (17.4°C) limits stress.
