: A.C., J.F., and S.H. are co-applicants on the patent (PCT/EP2013/069899) describing the use of chlorophyllafluorescence to determine the nutritional status of plants, and are founders of the university spin-out SpectraCrop IVS, marketing a hand-held device for predicting the P status of plants. For this reason, there may be a conflict of interest in order to show that the developed P model is able to predict the P status of barley leaves under field conditions. It should be noted that similar OJIP transients, as the ones recorded in this study, can be obtained by a broad range of standard chlorophyllafluorescence instruments, including Photon Systems Instruments (PSI), Walz, Hansatech, Opti Sciences, Phenospex and MultispeQ.
