Cut flower cultivation in the soil presents a act of challenge . industrial plant wellness , water , and environmental aspects , energy white plague , and polish optimisation are just a few of them . reasonableness for ErfGoed to await for an all - around root together with a number of partners , include Van der Knaap . After previous trials with Chrysanthemums , a play along - up trial with Lisianthus took place this summer in the ErfGoed testing adeptness in Moerkapelle .
The aim of these trials was to grow cut blossom that are usually grow in the grime , with an ErfGoed organization . The advantage of ErfGoedFloor with an reflux and flow arrangement is that urine rises simultaneously from below . This take into account the grower to continue irrigation , even when the flowers are close-fitting to being harvested . The craw itself stay dry , which is a plus in cut blossom finish .
SubstrateFor substratum ErfGoed turned to Van der Knaap . With the expertise that they have as a substrate manufacturer , they can offer up a choice of various customized solutions . Their horticultural advisors also have practical noesis of various crops , with which they can advise on the optimum finish shape .
A layer of approximately 20 cm of soil was applied on top of the ErfGoedFloor . In this trial , ErfGoed experiment with various substratum in collaboration with Van der Knaap . Two traditional substratum from practice , one substrate from pattern with additional coco peat mixed in , and a new , specially developed Lisianthus substrate . This sustainable substratum is based on coco peat , which has an open structure and is , therefore , suitable for multi - twelvemonth consumption .

ResultsThere was a very low failure pace on all substrates ; a maximal ofd 1 % . In recitation , this figure can rise to approximately 20 % . On the specially developed coco substratum only one branch was rejected ; a scotch of 0.1 % .
The substrate from exercise with the added coco peat had the best total scotch . On this substratum , the plant developed the heavy offshoot and it also scored richly on the number of unresolved and closed flowers . The add together coco ensures a good and unvarying moisture distribution .
During the trial , it became absolved that the sustainable Lisianthus substratum has more moisture available for the works compared to the other substrates . This makes it possible to add more nutrition , which was optimise step - by - whole step during the trial . The moisture buffer in the coco fibers take a leak the substratum more accomplishable .
According to Cock van Bommel , Business Development Manager at ErfGoed , it is clear that the ErfGoedFloor in combination with a gamey - quality ( coco ) substrate provides an excellent basis for the cultivation of thinned heyday . Due to the up and down body of water flow of the wane and flow arrangement , the substrate does not dry out out and the water intake stay constant during polish . This makes the cultivation process easy to control , especially in the field of fecundation and irrigation .
