Three Dutch cultivator have started measuring photosynthesis efficiency every moment at more than 1,000 samples per sec . They are doing so with a new type of photosynthesis efficiency sensor , from PhenoVation . Vincent Jalink give an update .
" Over the preceding twelvemonth , we have received many asking for a sensing element that can measure greenhouse photosynthesis efficiency . Although we introduced a alike solution in 2013 with the CropObserver , the mart was not ready for this innovation then . "
But now things are different , he observes . Six paradigm of the new sensor , CF2GO , have been make grow . Three of them are already in use by customers selected by PhenoVation . " These customers have experience with the CropObserver or already have experience with other photosynthesis efficiency sensor from other provider . "
Without a license , the CF2GO can be integrated into any mood computer or decision political platform . " The primary difference with the CropObserver is that this raw system will be amply integrated into Ledgnd ’s online weapons platform MyLedgnd . When the CropObserver was put in , we had to render the data ourselves . This worked but was unmanageable to scale and difficult to automatize . Now , by focalize more on data moulding and automating recurring pattern , the product becomes easier to incorporate and the scheme can take over specific tasks from the grower , such as fencing . "
The detector can be used stationary or on a moving mechanics such as a atomiser godsend , to which it can be mounted . The sensor is 30 % tawdry than its herald , the CropObserver .
CAM plantsAmong other things , Vincent sees chance for measuring photosynthesis efficiency in CAM plants . In growing potted plant , Vincent sees the fastest Return on Investment . " Here we can ensure higher output , as growers have less fearfulness of tip sunburn or discoloration at higher idle intensities . "
The sensor can be used to mensurate at CAM flora when a CAM works is no longer absorbing CO2 during the day . " This is a challenge with other sensing element that often solve with cartridge clip and can only measure a diminished part of the plant . With the CF2GO , we can measure photosynthesis efficiency up to 100 centimeters from the crop , without physical physical contact . As a consequence , the system offer not only more flexibility but also a much more arrant picture of what is happening in the greenhouse . "
DLIIn gain , the CF2GO offers the power to accurately determine the Daylight Integral ( DLI ) of plants . " By quantify photosynthesis efficiency in real - fourth dimension , we can determine exactly when a plant life is damaged by too in high spirits a light vividness at a yield time . We can also see if the total amount of light per Clarence Day ( the DLI ) is too high , which can go to lite tenseness and in the end plant damage . These insights help growers to interpose chop-chop and create the idealistic scant conditions . "
PhenoVation ’s new system can be applied in both illuminated and lightless culture . Especially in unexposed cultivation , light fluctuation in spring and autumn are sometimes so great that there is a risk of overexposure , Vincent make love . " For example , after four dark daylight , a sudden cheery twenty-four hour period can furnish too much light for the plant . In well-lighted culture , this system can help deploy LED lighting as efficiently as possible , so that the DLI is achieved with as little LED luminance and as much sun as potential . "
Automatic screeningVincent knows that there is still much to study about using the sensor , but he points out that previous experience has already show that robotlike screening is ' unquestionably feasible ' . " That is why we will get automatic screen at an orchid grower in January so that the plant never receive too much and never too little luminance . "
When using sensing element data for concealment decisiveness , the grower only has to pose the want DLI , Vincent explain . " CF2GO ensures that the plant life receives the accurate amount of light it require . Sometimes this can be slimly below the dictated DLI , but sometimes above it if the plant life feel ' happy ' , which we can monitor with real - time mensuration of Fv / Fm , ETR , TFM and NPQ(t ) . This four - stage depth psychology shows us exactly when the plant is fix too much or too little light . "
No AIPhenoVation ’s scheme measures straight plant wellness parametric quantity . " No AI is used to come up a correlation with photosynthesis . We really valuate the efficiency of photosynthesis . Of course , we do habituate certain models and algorithms to find patterns , but we want to keep everything as close as potential to really measuring flora health . "
trial in other crop , such as tomato and pepper , will follow in March .
