According to the European Water Framework Directive, as of 2027, no emissions from greenhouses may reach surface water. At the same time, horticulture is working towards autonomous cultivation. Starting next year, Wageningen University & Research, BU Greenhouse Horticulture will research how sensors and models for water and fertilizers can contribute to this goal. Researcher Francisco Mondaca Duarte explains: “The question is, how can we further optimize fertigation application in substrates?”
For emission-free cultivation, the grower—or the computer—must know how much water and fertilizer the crop uses.
