Abstract/Summary This paper aims to investigate the relationship between physicochemical properties of zinc fertiliser crystals and their uptake on foliar surfaces. Three kinds of zinc-containing crystal samples were synthesised by controlling temperature and solution chemical compositions. The samples and a commercial zinc fertiliser were applied on Capsicum leaves to determine and compare the foliar uptake of zinc. The samples were characterised by X-ray Diffraction (XRD), Fourier Transform Infrared spectroscopy (FTIR) and Scanning Electron Microscopy (SEM). The physical shapes of the samples determined via SEM were nanosheets, nanorods and nanospheres. The mineralogical and chemical compositions of samples determined by XRD and FTIR closely matched the theoretical mineral phases. The release of soluble zinc on the foliar surface appeared to be governed by the zinc solubility. The highest (9.3% of applied dose) and lowest (3.7% of applied dose) foliar uptake was obtained with the nanosheet crystals and the commercial zinc fertiliser, respectively. The nanocrystals can be used to control zinc release and foliar uptake with desired biological efficacy and low phytotoxicity risk.
