Two hours in an afternoon were enough to talk over a lot of new interesting insights from detector data point . Some 50 budding horticultural medical specialist were present . MBO Westland and Sendot jointly direct a Masterclass Plant brainwave last week . The venue was the World Horti Center in Naaldwijk , Netherlands .
Bert van Tol , former theater director of the Delft Research Group , of which Sendot was also part , kick back off the masterclass on 12 January with a piece of history . A phone of credit rose from the way at the speech sound of making an ISDN link ( yes , the internet was not as well-to-do 20 old age ago as it is today ) .

New sensorsBert discussed developments in areas such as engineering science in glasshouse horticulture . Sendot was founded seven years ago to contribute to this with sensors . It already result in sensors to valuate photosynthesis and O , and it does n’t stop there . " We are also working , together with Normec Groen Agro Control , on the growing of a sensor to evaluate viruses in genuine - time , " he says .
There are already many detector on the market . Arie Draaijer , a technical director and aged researcher at Sendot , estimates that there are already around 50 detector that can all measure different thing in and around the greenhouse . " And there will be many more , " he betoken . " We also want to start marketing sensing element to measure pH , CO2 , and leaf temperature , among other thing . "
He drew the comparison with a Formula 1 car . " There are about two hundred detector on and in that alone . " automobile racing is a top sport as far as Arie is concerned , and so is growing in the nursery . " grower can , with the avail of their gullible finger’s breadth as well as datum , steer the plant in such a room that it too can give birth top execution . "
get a line to read graphsIn the room , in plus to fighting growers , were perchance future agriculturalist . After all , cooperation had been sought with Lentiz MBO Westland for the event on 12 January . " We explicitly require to connect with practice as well , " said grooming coordinator Roel van Heijningen in his presentation .

Both the students , the cultivator , and other interested parties were acquaint with a serial of graphs during the afternoon , which , in accession to Arie , were also covered by Bonte de Jong of Phytoconsult and Robert Zuyderwijk of B+H Solutions . Arie especially dwelt on what can be discovered additionally by evaluate photosynthesis efficiency . " With that , you measure the plant ’s locomotive . It also says something about the product of a plant life . "
In the graphs Arie demonstrate , one of the thing that stood out was that flora do not deal every bit efficient with the light they invite during the twenty-four hour period every night . After a daytime with too much light , the plant need recovery time , which come at the expense of increment .

Not always lightingAs an deterrent example , Arie hash out Phalaenopsis with Bonte , a consultant narrow down in potted plant life ( including orchids ) . This is a CAM plant life , an abbreviation for Crassulacean Acid Metabolism . CAM plants , include many other decorative plants besides orchidaceous plant , come together their stomata during the day to grow without drying out . With stomata closed , they can not plunge CO2 . With the CO2 they absorb at night , they also farm during the twenty-four hours . But when the stored CO2 provision run out , it give up . extra kindling is , therefore , superfluous . The figures in the graphical record shown also made that unmortgaged . The technical term ' malate dip ' was mentioned . In that pickpocket , the stash away CO2 run out .
Bonte explicate that in practice , together with growers and with the service of sensor , he came to the conclusion that it may be necessary to start lighting afterwards at night . If grower do it earlier , but the malate pot is still empty , the plant ca n’t actually do anything with the light . Moreover , the twinkle that the cultivator gives the plant at Nox may cause the plant not to be able to use all the natural twinkle ( which does n’t be any surplus energy ) later during the mean solar day , but instead damage the plant .
Another lesson is that it can pay off not to turn artificial light source on all at once but to switch it up step by step . With dimmable light-emitting diode luminaires , this is potential these days . This preclude growers from stress the industrial plant and allows the works to speedily maximize light . " This form it possible to ultimately create more net assimilation with a lower PAR marrow . "
It raised the question from the audience whether there are already sensors that make it possible to see the position of the malate raft in advance . Arie waffle but did designate that a lesson could possibly be learned from night efficiency combined with knowledge about the malate pot .

What does the deployment of flatware spheres do to a crop?After a series of graphical record , John van Helden of Yookr had the chance to introduce his company . Yookr provide sensors and a dashboard to clear expose measurement data . Among others , the party is busy with test in cucumber cultivation at a North Limburg agriculturalist . Like Sendot , Yookr also has ambitions to keep generate new brainstorm with Modern sensors . " We are working day by day on a user - favorable fascia with which we desire to furnish progressively sophisticated harvest prognostication insights . "

The closing speaker at the masterclass was Robert Zuyderwijk . Besides working for B+H Solutions and others , he is also a intercrossed ( part - time ) lector in Business Administration Agribusiness at Inholland Delft . Standing in front of a way of students and concerned party is , therefore , nothing new for him . On Thursday , his presentation addressed how the effect of a particular nano fertilizer free-base on silver spheres can be demonstrated using detector . After all : it sound a spot abracadabra , and so cultivator would like to see it corroborate in datum , in plus to in the craw .

Excellent results have been achieved in gerbera crops , among others , as well as in love apple , of which Robert shows some graphs . The special fertiliser from the German - origin company helps spread out the light better through the works and also helps the crop cope better with dispute in light . This prevents plant stress and results in increase yield . In the case of genus Gerbera , the impregnable gist was seen in fountain , during bright abstemious changes . In the tomato graphical record , Robert point to the ETR , the Energy Transfer proportion . This was high in the treated crop than in the untreated crop . In several crops , B+H Solutions sees that works experience less abiotic tension when using their fertilizer , making tomato plants less susceptible to tomato spy wilt virus ( TSWV ) , among other thing .
Sharing sixth sense more oftenThe material conclusion word was for Roel . He briefly charter the audience digitally into the nursery . The glasshouse the pupil work in are connect to Kassim , an on-line model tool for mood control . The students learn what turning the node can do to the crop and climate in the greenhouse without immediately being punished for a misunderstanding . For the two nursery compartments in the World Horti Center , the students are not allowed to hold the climate computer themselves .
Partly with the aid of Kassim , the would - be horticultural specialists are gaining fresh insights . The master key division also undoubtedly allow for new insights , both for the bookman and other attendees . Sendot , Phytoconsult , Yookr , and U stand for to unionise more frequent Roger Sessions around Plant Monitor and Plant Insights . Erwin Gräfe , Commercial Manager of Sendot , is felicitous to explicate more .
