Het Groene Hart


Precision and Sustainability at the Heart of it All

On the farm of farmer Jasper Roubos, Het Groene Hart, we work together to promote and demonstrate sustainability in practice and share our knowledge in this area with farmers, citizens, policymakers and other stakeholders. Jasper keeps a close eye on key production factors such as soil fertility, quality seed selection, and water management – in addition to smart weed, disease and pest control, optimum fertilization and proper handling and storage of the harvest. Crop rotation is of major importance at Het Groene Hart to ensure retained soil fertility. At harvest, wheat and straw are shredded and left in the field to improve the organic matter content of the soil. To create a good nutrient base, fields are also fertilized with manure and cover crops are planted to contribute to the rich organic matter in the soil.


Technology is progressing even faster with the evolution of communication networks and the availability of a wide range of new sensors, opening up new opportunities for farming. Respectively, Het Groene Hart participates in The Internet of Food and Farm 2020 (IoF 2020) project funded by the EU to develop systems integrating sensor technology, real-time data analysis like soil moisture, crop health, weather data, etc. to improve crop performance and farm efficiency.

We’ve always been interested in sustainability and motivated to contribute to a better environment. Even in our home we separate all our garbage and run completely on solar energy. The farm is named after the area we are in; “Het Groene Hart”, which literally means “The Green Heart”. We think it is quite fitting that it is now a place that brings sustainable agricultural practices to life. When Bayer approached us about becoming a ForwardFarm, it was a natural extension to the work we were already implementing on the farm. Bayer supports us by providing innovative solutions, valuable services and cutting-edge technology for our farm, so that we can meet the needs of not only our business, but also the environment and society in which we live.

Pollinator Care - Varroa-Gate Protects Honeybees

In partnership with beekeeper Erik Dolstra, Jasper had several bee hotels installed on Het Groene Hart – all of them equipped with Varroa-Gates at the entrance to the hive. The Varroa-Gates are airlock devices that liberates a small amount of acaricide every time a bee passes through the gate. This simple measure is sufficient to control the mite population but harmless to the bee, keeping a healthy pollinator population on the farm.
