Bio

Joost de Willebois is the founder and owner of Domaine J. de Villebois, a family-run winery in France's Loire Valley.

Originally from the Netherlands, Joost descends from a French lineage dating back to 1180. In 2004, he and his wife, Miguela, acquired a 10-hectare vineyard in Mareuil-sur-Cher, marking the beginning of their winemaking journey.

They focused on producing Sauvignon Blanc, aiming to become specialists in this varietal within the Loire region. Over the years, the domaine expanded its reach across key appellations like Sancerre, Pouilly-Fumé, and Menetou-Salon.

Joost transitioned from a career in finance to dedicate himself fully to winemaking, emphasizing sustainable practices. Today, Domaine J. de Villebois is recognized for its high-quality Sauvignon Blancs and commitment to environmental management.

Results since implementing StimBlue+
StimBlue+ boosts nitrogen availability by 200% by attracting nitrogen-fixing bacteria, leading to more amino acid production and plant growth. It also improves calcium uptake by 3.5% through microbe activation. Treated plants gain natural pest protection from increased beneficial organisms, cutting down the need for chemical fertilizers and pesticides while supporting healthier, more sustainable crops.

The soil microbiome plays a critical role in optimizing crop yields, nutrition, and stress resilience. To assess the impact of StimBlue+ on the microbial pathways essential for wine grape development, we partnered with Biome Makers, a leader in assessing soil health at scale. Through their rigorous analysis, we examined the influence of StimBlue+ on soil microorganisms and their functions, providing incredible insights into how our product enhances soil health and vine performance. The tests were done on the vineyards of Domaine J. de Villebois.

Testimonial from BiomeMakers:

"With StimBlue+, we saw a unique boost in nutrient availability. Even through foliar application, BeCrop analysis confirmed these effects across fields, highlighting the reach and effectiveness of this biostimulant" Juan Rebori, BiomeMakers

La Junquera is a pioneering regenerative farm located in the Altiplano region of Murcia, southeastern Spain.

Spanning approximately 1,100 hectares, it stands as one of Europe’s largest regenerative agriculture projects, operating in one of the most desertified areas of the Iberian Peninsula. La Junquera transitioned to organic farming in 2010 and adopted regenerative practices in 2015. The farm's methods focus on restoring soil health, enhancing water retention, and boosting biodiversity. Key practices include:​

Soil Regeneration: Utilizing cover crops, vermicomposting, and minimal tillage to improve soil fertility.​

Water Management: Constructing swales, ponds, and sediment traps to capture and distribute rainfall efficiently.​

Biodiversity Enhancement: Planting native species, establishing wildlife corridors, and integrating livestock like the endangered Murcian-Levantine cow to promote ecosystem balance.​

These efforts have led to a significant increase in soil organic matter, from 2% to 6%, and the restoration of 2,500 hectares of degraded land.​

Besides their farming efforts, La Junquera hosts the Regeneration Academy, led by Yanniek Schoonhoven, offering educational programs in agroecology, soil conservation, and sustainable farming.

Isabella Hof

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.
