Bio
Isabella Hof is a pioneering organic onion farmer in the Netherlands, taking over the farm from her father, who paved a path at a time when the market for organic was lacking.
Now, they have two businesses: their farm and an onion-sorting company. The main crops on their 200-hectare farm include onions, seed onions and flax, and they also grow wheat, barley, sugar beets, potatoes and grass seeds. The onions they grow and purchase are exported and sold to consumers through retail outlets in the Netherlands.
Due to the pressure of chemicals on the soil and climate, they have seen yields decline and weeds, diseases and pests increase for years, both on their farm and those of their growers. Because of these concerns, Isabella started taking courses at De Oorsprong and Agrosymbio and has begun experimenting with regenerative practices. Isabella is passionate about building healthier soil, products and business, and involving their growers along the way.
