Drought 2018: maize crop benefits from treated wastewater
by Ruud Bartholomeus PhD MSc

The 2018 drought affected agriculture heavily, especially in the sandy Eastern part of the Netherlands where freshwater supply by rivers is not possible. Treated wastewater is increasingly being considered as freshwater source for irrigation. Our experimental site in Haaksbergen clearly showed the benefits for crop yields of subsurface irrigation using treated wastewater. Additionally, the drought provides insight in the ‘worst...
