Digitizing your polish . That is something agriculturalist can not head off . But how to get start ? During his creation at the Delphy , Glastuinbouw Nederland , Greenport West - Holland , Zentoo , Inholland , and Priva Digitalization Event , Woody Maijers of Greenport West - Holland adduce that there are uncounted style to do so . " think , what was impossible yesterday may be possible today . When is the right metre for you to commence with this ontogenesis ? " he asks .
At Tuesday ’s event , practical putz were offered to vegetable and decorative works growers . Guests could choose three topics from 12 shop . The presentations covered various topic , like uncommitted sensor and their uses , climate tools , and digitalisation combined with sustainability and cybersecurity .
Measuring photosynthesisOne of those workshop was about measuring photosynthesis . Sendot ’s Arie Draaijer and Delphy ’s Alex van Klink presented this session . Above and below - ground factors affect the sensors and their mensuration . call back of lead , CO2 , EC , and Ph as some of these variable factors . The goal is , thus , to get results as speedily as possible .
A sensing element ’s cosmopolitan function is to monitor yield growth . Photosynthesis drives that . When that is not at its honest , the plant can be damaged . When photosynthesis is subpar , under artificial light , energy is wasted . Measuring photosynthesis gives insight into the light storey under which plants can convert energy effectively .
When light hit a plant , three thing happen :
Alex brought along a Phalaenopsis for testing . The sensor was attached to the leafage , and a torch was used to introduce different lightsome intensity . The graph react immediately . The photosynthesis efficiency was instantly translated into ETR ( Electron Transfer pace ) .
It is calculate as follow ; divisor x par x efficiency . ETR does not account for generative / vegetive crops , photorespiration stage , or adjustment process . It does , however , take into account military unit such as wanton , natural gas interchange , and temperature .
What stood out was that there is a upper limit to which light bear on photosynthesis . One of the growers present attest to that . His greenhouse sensing element quantify that same burden . He saw that he did not need to light his Phalaenopsis harvest for the standard 16 hours . Fourteen was measurably sufficient to develop photosynthesis to grow a safe production . For this farm , therefore , 14 hours of pic is optimal .
Here is an impression of the consequence via a picture study .
