cultivator who want to have their supply and drain piss tested have to gather up a sampling and broadcast it to a laboratory . They then have to wait a few day for the result . For these reasons , this surgical procedure is done only every 7 – 14 days . By measuring the water with an ion - specific meter in - situ , the result is known in about an hour , and the agriculturist can therefore make immediate adjustments if necessary . In addition , the creation of data point in - situ leaves space for next automation of the adjustments . The Business Unit Greenhouse Horticulture and Flower Bulbs of Wageningen University & Research are investigating the practical use of goods and services of Celine , an ion - specific measuring equipment , and the benefit of a so - called ‘ ion - specific cultivation . ’
A few years ago , The Sensor Factory launch the Celine , a tool for conducting ion - specific measurements which use the proficiency of hairlike dielectrolysis . WUR has created a consortium to look into how the Celine can comfortably be used and improve . WUR aims to hoard enough information to compare ion - specific cultivation ( ISC ) ( daily adjustment per ion ) versus conventional practice session ( CC ) ( day-by-day adjustment on EC ) and to prove the higher efficiency of the former . ISC is believed to trim down ion fluctuation in the ancestor environment when compared to CC , which can ultimately increase the yield by 5 % .
Laboratory testsLaboratory test were first guide to examine the consequence of ion fluctuations on yield . WUR has then run a comparing trial between ISC and CC , which , however , did not show any significant gain for ISC due to technological failure in applying the daily adaptations to ISC . In fact , to apply everyday adjustment , it is necessary to hold a plant food injection unit . For this reason , the probe fall out in 2021 at the vegetable growing company Royal Pride , and the Celine is currently being test by the tomato grower Kwekerij Lijntje , where both raiser own fertilizer injection unit .
The study mainly wait at the macronutrients NH4 , K , Ca , Mg , Na , NO3 , Cl , SO4 , PO4 , and HCO3 . Both the drainpipe piss and the irrigation water are examined . That goes through a tobacco pipe to the Celine . The measurement is therefore reflex ; the agriculturist , therefore , does not ask to take samples . During the research , the data about the ions are loaded into a WUR ’s nutrient good word platform ( NRP ) , the BAB ( Bemesting Advies Basis ) , which elaborates the data point from Celine and suggests the day-to-day adjustments to the grower .
Autonomous fertigationThe utilisation of an ion - specific meter in - situ in combining with an NRP would especially be of interest for those orbit where less noesis is usable about fertilization and laboratory depth psychology are too slow or too expensive . or else , for more advanced glasshouse , this compounding is the first step towards autonomous fertigation systems .
