What is this calculator for?

This calculator works out the seed quantities of a forage mixture from the share of each species. Starting from the target share of plants per m² for each species in the mixture and its germination rate, it gives the seeding rate of each one needed to reach the overall target density.

Who is this tool for?

It is mainly intended for agricultural technicians and agronomists, to fine-tune advice on forage mixtures. It is also for farmers who simply want to work out their seeding rate, and for agronomy students.
