At Meewisse Roses , Moleaer ’s Neo 150 Nanobubble Generator was installed for a pilot project to closely examine the added value of atomic number 8 nanobubbles in rosaceous cultivation . The installation was handled by Royal Brinkman , one of Moleaer ’s distributors and the leading gardening industry provider .
Meewisse ’s body of water scheme comprise of a freshwater tank , a dirty drain army tank and a clean drainpipe tank . In the mix tank , run out water and fresh weewee are sundry . The Neo 150 circulates the clean drain storage tank and enrich it with oxygen nanobubbles up to 35 to 40 mg / l dissolved oxygen storey ( DO ) . The DO concentration is show on the Neo ’s built in presentation .
Meewisseand Moleaer conducted frequent measurements and analyses throughout the pilot film to confirm the whim that oxygen nanobubbles put up to better water quality , quelling of plant pathogens and better nutrient uptake . In the end , measurements showed that the water from the dripper incorporate more than 200 % DO . This is up from 70 % - a big pace onward .
Tom Meewisse : “ The finish of a rosaceous craw on rockwool is special in a way , because the rose is a perennial shrub . That means the slab will often get entirely cover with beginning and become more compacted , causing less aeration into the lower parts of the mat . The amount of oxygen that can be deliver through the irrigation water supply thus becomes particularly of import . I was rather curious to see if we could improve this with the Moleaer Nanobubble Generator . ”
Michiel de Jong of Moleaer : “ For other craw on rockwool , we already have intercourse less O is useable in the lower parts of a slab , which can result in decreased root caliber , low-spirited nutrient uptake and even an surround contributing to the growing of pathogen like Pythium , Fusarium or Phythopthora . At the bottom of the slab , the localized oxygen demand is higher than the oxygen supply . plant can deal out with that to a certain extent , because in the Netherlands growers are at the top of their biz when it comes to climate , light , and fertilization . So visible defect are not to be expect , such as can be watch in soil - bound cultivations . Nevertheless , by ameliorate the availability of oxygen you may ameliorate root quality , nutrient uptake and craw resilience . ”
Tom Meewisse : “ I knew I could n’t immediately make comparison in the greenhouse . So , together with Moleaer we wait and measured meticulously . Every other week they gossip , following the water system from source to irrigation to drain and back to irrigation . We collected a lot of information that way . What also helped my understanding is that at some point , we flip-flop the nanobubble author off and on purposely , with interval of a couple of week . The atomic number 8 levels in the piddle was much higher when the nanobubbles generator was turned on , and pathogen analyses of the water showed increasingly lower amounts of Fusarium and Pythium . Not that those values were high to start out with , since we also expend a UV disinfector , but the nanobubbles still made quite a big difference . Moleaer also had weekly plant sap analytic thinking carry out , which prove that atomic number 20 consumption was higher in the week that we applied oxygen enrichment , and broken when the nanobubble generator was exchange off . For me , it ’s about the complete picture that I get from all this data : that nanobubbles chip in to sizable water and a source zone that ’s richer in break up oxygen , which conduce positively to cultivation . It ’s difficult to see it in the crop directly , but overall , higher atomic number 8 levels , white irrigation stock and better calcium ingestion , convinced me to continue with the Moleaer unit . ”
