How many round in the glasshouse does a agriculturalist make in a day ? Enough to sometimes ‘ not really ’ see sure things . For example , a very dull , ill-gotten cloth filter or a condensation gutter that empty directly into the neat drain . latterly , during a day on which water in Dutch horticulture -including the WaterEvent- was central , some seventy mass foregather to reflect on H2O quality management and ozone technology in nursery horticulture . After all , you do n’t just add blank urine into the nursery in a boxful . In the running play - up to January 1 , 2018 , when in the Netherlands the water purification obligation was introduced , raiser had no choice but to follow with it : a water purification plant for their sack piddle . " For a time a lot of attending was paid to the water that leaves the nursery , " say Rinze Noordam of Agrozone . “ In the meantime , however , that focusing has shifted much more to the piss inside the greenhouse . Also legitimate , because if the water in the greenhouse is to stay in the water system , as a grower you naturally want the character of this water to be optimum .
advance in equipmentMuch is already get it on in the field of H2O , but at the same time much is still unknown . During the event , Jim van Ruijven , urine specialist at Wageningen University & Research ( WUR ) , talk over all the research that has been done over the years and the knowledge that has already been gathered . Knowledge also about ozone and the program program to agricultural water , with which Agrozone has also had extensive experience since its establishment in 2008 . Jim pertain that installation were already being develop in the 1980s and 1990s with which good results were achieved , but at the same time it turned out that the same answer were not always achieved , partly because the weewee quality was not measured at the time , while the materials of the installations were not ozone resistant . Rinze speaking
In the interim , that has been addressed and the critical period from the last century are a thing of the past . In fact , ozone was already successfully applied in 2014 in a WUR project with the emission - free greenhouse . " And since half a twelvemonth also in four departments of our fogey - complimentary greenhouse , " says Rinze .
But what exactly is ozone ? Roy Imming of Agrozone gave a presentation about this . Very shortly , it comes down to the fact that ozone is a born gas pedal that , after undertake pollution , is converted into oxygen , which is eagerly used by plant roots . This result in strong , white roots , and cultivator like to see that .
counterbalance in the pictureThat is , if the relaxation of the water supply organization is also in order of magnitude . " And there is still much to be gained , " says Rinze . " Everyone is talking about ‘ resilient culture , ’ ‘ not want to defeat everything ’ and especially ‘ balance in the water supply system ’ , but we guess the question is exactly what that ‘ proportionality ’ is . Not everything is clean about that yet . A water supply scan , which we offer to growers [ during the event , pepper grower Color Capsicum won a complimentary H2O scan ] , help to get an melodic theme of the timbre of the water that enters into the industrial plant and what the water quality is if it leave the plant . If you have determined that , the grower can start ensure based on that data point . "
Measuring really is know , according to Rinze . “ Now most growers often have their disinfectant examine once , twice or maybe three times a class , but that is no indicant about the quality of the water that ends up with the plant . And even the installation of an ozone antimicrobic alone is not enough to achieve that .
" Through meetings such as this one , with professional equal , we can take steps , create awareness and also learn from each other not to remain stuck in their own imaginativeness . Taking a moment to talk about urine , especially with the grower for whom it is not his chief occupation , is important . The vision of the raiser is what we want as feedback for the technology and the total water system . ”
