Abstract Stricter legislation forces growers to decrease discharge of water with nitrogen, phosphate and plant protection products. A demonstration was set-up to compare emission free cultivation with a traditional growing method. Goal was to achieve a comparable yield and quality. Essential differences were disinfection of rainwater, ring pipes for drip irrigation, no discharge of first drain in cultivation, a filter without rinsing and weekly analysis of the nutrient solution. It appeared that production and quality were similar as were other climate parameters. Water use was higher in emission free crop, discharge was 4% in traditional crop realizing 152 kg N discharge per ha per year, which was more than the allowed 133 kg. Specific end cultivation strategy is useful to decrease nitrogen and phosphate stored in slabs and stock containers.
