Seed ROI & Rate Calculators
Two free tools used by commercial seed buyers worldwide. Estimate the profitability of a planting programme and calculate how much seed you actually need per hectare — accounting for germination, target plant density and field loss.
Estimates are indicative only — actual yield and seed requirement depend on agronomy, climate, soil and management. SeedMatchGroup is not responsible for decisions made on the basis of these calculators.
