“ What we presently do is direct the plant using the environment , but my dubiousness is whether that is a serious approach . Would it not be better to look at the plant ’s energy ? We have to involve the craw itself in the automation and the ascendance , ” says Peter Kamp , craw systems trailblazer at Priva .
Managing water balance in the cropOn January 20 , 2022 , Peter presented at a webinar hosted by OMAFRA that focus on Priva ’s BioLogics glide path to glasshouse crop direction . The BioLogics approach focuses on bring off the piddle balance in the crop rather than centre primarily on temperature direction .
As Peter explains , monitoring the glasshouse temperature and other environmental parameters will always remain important but may not continue the most effective way of steering harvest growth . likewise , focusing only on photosynthesis and the output of scratch does not paint the whole picture .
“ Considering photosynthesis is really of import because , without the yield of sugars , the works can not make different plant organs and grow . But it is n’t the only matter . When baking , only sugar and flour does n’t make a cake . We need good penetration into water balance , ” say Peter .
craw guidance according to urine symmetry requires an understanding of water uptake , fixation by the works , and transpiration . To do so , Peter has ferment diligently with Priva ’s Horticulture Innovation Lab and with growers to develop development curves that chart the transpiration rate over time . The curves let in both an upper and lower limit beyond which the crop suffers dramatically , as well as an internal envelope where optimal increase occurs . On this curve , Peter has identify six setpoints that could be used to guide the crop .
Reducing the number of setpoints“With Priva ’s BioLogics for plant growth , we want to reduce the number of setpoints by focusing on the biorhythm of the plant and concentrate on water balance . We tested the traditional control and our new control for steerage . Under the new control , it was much more logical , ” explains Peter .
oversee air flow is a key method acting of controlling transpiration and the crop water balance , leave to improved production and harvest lineament by limiting the relative incidence of physiological disorders and susceptibleness to disease . As Peter explicate , merely look at the humidness levels in the nursery does not accurately present the water balance as flow of air is essential to transpiration under any humidity conditions .
“ If we take a foliage in an unvented greenhouse , without airflow , at 20C and 80 % comparative humidity and equate it to one in a greenhouse at 95 % relative humidity and air out , you ’ll find that more transpiration occurs under the high-pitched humidness tier due the airflow disrupting the folio boundary layer , ” Peter explains .
Priva ’s BioLogics principles applied through PlantonomyPriva has been testing and developing the BioLogics refinement method acting for more than ten years and has translate the principle into its New technology , Plantonomy . Plantonomy is a cloud - based service that integrates seamlessly in the Priva platform and uses smart algorithm to supervise the crop ’s biorhythm . In many cases , no additional sensors or modules are call for .
