The project consists of four components, each contributing to concrete solutions and practical recommendations for the sector.

The first part of the project focuses on optimizing nitrogen fertilization. Fertilization guidelines will be updated and aligned with changing climate conditions, cultivation methods, and varieties. New visualization tools will make these recommendations more user‑friendly. In addition, innovative fertilizers and techniques, such as band fertilization and split applications, are being tested for their impact on nitrogen emissions and economic feasibility.

Once nitrogen is applied to the field, it must be taken up to prevent leaching. If this does not happen through the crop, other strategies are needed to retain nutrients or remove them in a controlled way. Experiments include (mixtures of) cover crops, undersowing, incorporating green manures, and removing crop residues to reduce nitrogen losses and improve nutrient cycling.

Sometimes it is not possible to manage all nutrients through the measures above. In such cases, so‑called ‘end-of-pipe’ techniques are required to extract nitrogen from water. The techniques studied in this project focus on reusing drainage water in greenhouse cultivation and reducing nutrient leaching in soft fruit production through smart drainage systems.

Through study days, practice‑oriented publications, and collaboration with the sector, we ensure that the results are widely shared. Active feedback is also provided to policymakers and researchers so that the insights contribute to the development of a more sustainable agriculture in Flanders.
