The weewee quality in the greenhouse gardening areas in the management orbit of Delfland in the Netherlands shows positive developments in 2018 once more : a decrease in plant food and craw tribute residue has been noted in recent measurements . This is good news for everyone using the land , the Delfland water board says . “ Because clean water is something we can all benefit from , even the nursery horticultural sector itself . ”
Less plant food use intend less chance of duckweed in the Schie , de Vliet , and other H2O . Fewer pesticides in the water mean that , for greenhouse horticulture , more allowed products for pest control remain .
level presentationUnder the watchful eye of many interested parties , Ingrid ter Woorst of the water board presented the consequence of the measurements of the pee quality in 2018 on Thursday the 7th of March . These testify that the positively charged trend of N that was apparent in the previous years has continued in 2018 . The amount of harvest protective covering products found has decreased . The concentration of detected substances has however increased slightly in comparison to last twelvemonth . But the assiduousness of atomic number 7 and pesticide do both run into the amount given by the achievement indicators for 2018 .
Ter Woorst : “ It was pretty tightlipped though , since 2018 had been an exceptional twelvemonth due to the drouth , fortuitously it looks positive now . We are headed in the right direction , not just because of the piddle quality norms we have to conform to , but because , in the end , unclouded and healthy water is important to everyone . We have a plebeian goal : for us because of the water quality and the glasshouse horticultural sphere because of the admission policy , fair competition , and sustainable image . ”
According to Ter Woorst , the good results are chiefly due to the intensive cooperation of all the partners : manufacture association Glastuinbouw Nederland , the craw protection manufacturers merge under Nefyto and also the cooperation with the greenhouse gardening entrepreneurs themselves . “ Among others , this is also due to the fix - ground approach , in which we intensely supervise all greenhouse horticulture polder and together with entrepreneurs discover solution to their problem . But we need to stay alert . Because , unfortunately , we notice that if we were to leave one of these polder the attention to these trouble decrease andsome enterpriser finish up have similar mistakes again . ”
Jacco Vooijs and Theo Ammerlaan , presidents of Greenhouse Horticulture Westland and Eastland respectively , are also happy with the results . Vooijs : “ The current approach is working . The entrepreneurs are becoming more and more aware of the water . The drouth of 2018 has also bring to this : as refreshed water is no longer take for granted , it has become necessary to be more conservative with it .
I am happy that both the regional water authorities and the entrepreneur make an effort to get hold forward-looking ways to reuse as much fresh urine as they can . defilement with pesticide and fertilizers plainly does n’t descend in line with this idea . I trust that the next talk from Delfland also see that the current intensive approach is devote off and that the collaboration in all areas is being continued . ”
