Agronomic summary
Corsica (brown soils over granite, red soils over schist, alluvial eastern plain) has a strongly Mediterranean terroir: 23.8°C summer, 2,268 GDD and 347 frost-free days. Sunflower, marginal on an island dominated by orchards and viticulture, still finds a warm, sun-rich environment. LS Forsy, LS Globsun and L 25-02-IOS are best suited to the eastern plain, with supplemental irrigation to offset the typical July–August water deficit of the insular climate.
