Nuseed has world-class Innovation Centers in each hemisphere, earned seed sales in over 30 countries, and developed R&D programs, advanced trials and facilities in Australia, Europe, North America and South America.

Brent has helped drive Nuseed’s competitive market landscape and has maintained social responsibility in the geographies Nuseed operates. Nuseed has pledged a commitment to ‘Value Beyond Yield®’, which means that we are not content to simply meet expectations, but rather strive to surpass what is typically expected from a top seed and services company.
