Voorkomen en bestrijden emissies kasteelten : WP1. Waterstromen afwijkend van drainwater
Dutch greenhouse horticulture is putting much effort into implementing measures to reduce emission of nutrients and plant protection products to surface water. This report shows results of analyses of cleaning waterproduced during crop interchange of substrate grown crops, water flows currently not included in legislationon nitrogen emission and obligated purification of discharge water. Water for cleaning the inside of windows,irrigation pipelines and cultivation gutters/tables is evaluated. Measurements show that discharge of these waterflows to surface water can cause exceedance of surface water quality standards. Therefore, best practices aredescribed to prevent emission of nutrients and plant protection products with these water flows. First step is to adapt the cultivation system or cleaning strategy in such a way that collection of the water is possible. This creates an option for reuse or treatment of the water. Second step is close consideration of the use of cleaningor disinfection agents, as some of these products can cause damage to the new crop. If reuse is undesirable,it is advisable to purify the water before discharge for the removal of plant protection agents, by using a BZG approved installation, as this significantly decreases the emission of plant protection products.
