Cost source Scenario

Resowing Without resowing
Prevention Equipment (scaring), time spent... Not rated

Lower yield Non-optimal planting date: €110 Non-optimal population (density and structure): €129

Price reduction on oil content Not relevant

Cost of re-sowing Passage − seed: €119 Not relevant

TOTAL (excluding prevention) €229 €129
