A Partnership for Technology-Driven Sustainable Agriculture

The state-of-the-art BraZander nursery is owned and operated by Rob Brabander and Paul Zantman. Together, Rob and Paul are passionate about producing tomatoes and other vegetables of the highest quality – not just in yield, but also in flavor and disease resistance. Since the beginning of their partnership in 2001, the duo has been driven by their pursuit of modern, technology-driven growing solutions to allow them to grow a bountiful crop in a sustainable manner. The growers partnered with Bayer in 2018 to establish the De Ruiter Experience Center, which welcomes thousands of visitors – growers, traders, experts and consumers – each year to see how new tomato varieties are being developed and produced using the latest breeding, cultivation, digital, recycling and sustainable pest management technologies as well as intelligent glasshouse climate steering.


Not only are visitors introduced to the latest technologies, but they can also see, smell and taste some of the approximately 300 tomato varieties offered by De Ruiter. With the Experience Center, Rob and Paul are working together with the De Ruiter team to develop smart ways to grow tasty and healthier crops that are both more environmentally friendly and economically sustainable. Together with Bayer ForwardFarming, sustainability practices are embraced and demonstrated even stronger.

  • Farm name and location: BraZander, Bleiswijk, near Rotterdam and The Hague.

  • History: Sharing a common vision on vegetable production, Paul and Rob joined forces in 2001. After a small-scale start, BraZander expanded to five locations including the De Ruiter Experience Center.

  • Farm Size: 12 hectares.

  • Primary crops: Tomatoes – for the fresh fruit market and approximately 300 varieties in testing.

Though the Netherlands is recognized internationally for its innovative technology and best practices in glasshouse production, it is often not known just how sustainably we are working and just how safe and healthy our products are. We hope that the connection with Bayer will help the glasshouse tomato community bring that message to the broader public in a clear, transparent and continuous way.

Responsible Water Use

The BraZander team utilizes a system of drippers to transport water and nutrient solutions to the tomato plants. Depending on the phase of the crops, there are approximately 20 90-second dripping sessions per day. An adult plant needs between 2 and 4 liters of water per day, with the total amount varying based on the amount of light the plant receives as well as the temperature of its environment. Plants are given just enough water in response to light intensity, humidity and temperature, and the team uses a climate computer as a central tool to ensure water efficiency.


The amount of water given to the plants always exceeds the uptake amount, but a 30% drainage is implemented to prevent salt accumulation in the root zone. We collect and reuse all of the water that the plant does not absorb, so no water is wasted. Even the condensed water on the glasshouse’s ceiling is recycled.
