Paper on plant response to e-fertilizer

This paper will present the results on plant response to efertilizerThe eFertilizer will be based on a PEDOTbased conducting polymer bearing moieties composed of nitrogen eg ammonium ions developed in WP1 The mechanism of nitrogen release is based on the reductionoxidation of PEDOT In order to control the nitrogen release the number of ammonium species per polymer chain the crosslinking of PEDOT and the charachteristics type of the electrical stimuli and will be tuned and their efficiency to release ammonium will be evaluated We will evaluate the nitrogen gradients in soil and gel medium using various stimulation protocols constant release accelerated release and pulsing in various frequencies The electronic control offers flexibility on the release rate of the nitrogen Bordeaux INP LiUAs a next step we will evaluate the electronically controlled nitrogen response in various plants Hydroponically grown plants will be subjected to various changes in nitrogen availability through electronic control Then the release of compounds from root surfaces on potgrown plants will be monitored This will be based on a recently developed technique for monitoring of plantsoil interactions microdialysis The ultimate goal is to identifying key molecules that are released by the plant in order to design better fertilizers The experiments will be performed with various types of plants cereals ornamental plants and tree seedlings and in different growth settings This will enable generalization of results and help designing different release functions from the materials used for fertilization SLU
