Limiting environmental impact

NuReDrain: Nutrients Removal and Recovery from Drainage Water (2016 – 2020)

Contact: Els Pauwels (PCS, Centre for Ornamental Plant Research)


The North Sea region is recognized as an intensive farming area. Nutrient inputs from land have resulted in eutrophication in rivers, lakes, estuaries and coastal zones. This shared territorial challenge will be combined with efficient use of the resource phosphorus.

Bio4safe: An innovative approach to enhance resource efficiency and safeguarding by using biostimulants and innovative sensors in horticulture (2017 – 2021)

Contact: Els Pauwels (PCS, Centre for Ornamental Plant Research)

This project aims to reduce water and fertilizer use in horticulture by using biostimulants and innovative tools. This combination will result in up to 20% reduction of water and 10% of fertilizers, depending on the crop. By including BS based on seaweeds, economic opportunities for seaweed producers will be created.

PROSODOL: Strategies to improve and protect soil quality from the disposal of olive oil mills´wastes in the mediterranean region (2009 – 2013)

Contact: Maria Doula (Benaki Phytopathological Institute), Federico Tinivella (CeRSAA)


The consumption of olives and olive oil is believed to bring health, however, the side products (wastewaters-OOMW and solid wastes-SW) from their production and treatment could be disastrous for the environment if no precautions are taken.

Vlaio – Supply strategy of nitrogen and water in soil cultivation strawberry as a sustainable transition towards elevated quality in taste and shelf life (2014 – 2018)

Contact: Pieter Janssens (Bodemkundige Dienst België)


Designing a fertigation table to meet the demands of productivity, fruit quality and limited emission of nutrients towards the environment in soil cultivations of strawberry. Different fertilizations trials are executed in the multiple cultivation systems of strawberry. Using soil humid balances and sensors the irrigation is monitored and adapted.

Growing qualitative plants on tray and container fields whit reduction of nutrient leaching (2012-2014)

Contact: Peter Melis (Proefcentrum Hoogstraten)


The purpose was to find a solution for the run-off of nitrate in the drain water. Leaching curves for nitrate were determined for different dosages of fertilizers. Based on these data a model was suggested to collect drain water after each fertilization in order to respect the allowed nitrate levels in natural waters.

REDUNG: Reduction of nitrate leaching in soil bound vegetable crops under protection (2013 – 2017)

Contact: Sara Crappé (Provinciaal Proefcentrum  voor de Groenteteelt Oost-Vlaanderen vzw)


REDUNG aims to provide “best practices” for growers in order to prevent nitrate leaching in soil bound vegetable crops under protection by reasoned irrigation and fertilisation.To achieve this a decision support system is developed based on a evaporations model (using soil sensors). Moreover, the salification effect of different fertilizer regimes is observed. Guidelines are prepared to minimize the growers needs to flush their soils due to high salinity levels.

Innovative approaches for nitrate reduction in agricultural and horticultural areas (2016 – 2020)

Contact: Elise Vandewoestijne (Provinciaal Proefcentrum  voor de Groenteteelt Oost-Vlaanderen vzw)


This project aims to develop a best available technique for nitrate removal from drainage water. With denitrification techniques, a maximum concentration of 50 mg nitrate/L will be provided in the drainage water.

FERTILIFE: Agricultural carbonic fertilization with ceramic industry greenhouse gases emissions (2015 – 2018)

Contact: Maria Dolores Corvinos (Sistemas Avanzados Energeticos S.I)


The project focuses on reducing GHG emossions of ceramic industries in the area of Castellón de la Plana using the CO2 captured in agriculture, promoting it as a natural sink for CO2 to enhance this residual gas by using it as acidifier in irrigation water.
