Brick recyclate, as same as brick, excel with very high porosity. for this reason this work deals with possible implementation of plant growth aids (fertilizers) on the inside surface of such highly porous material. This work studies possibilities of preparation of brick recyclate with the content of components supporting plant growth and what is maximum amount of supporting substances, that later will be released back into surrounding enviroment (soil), is possible to incorporate into the brick recyclate. Brick recyclate is a material that can bind water in the soil and nourish cultivated plants at the same time. Brick recyclate was saturated with commercial NPK fertilizer and laboratory prepared fertilizer based on NPK. Such prepared brick recyclate was used for growth experiment on agricultural plants (tomatoes, corn). Prepared brick recyclate was subjected to x‑ray diffraction, thermogravimetry and differential thermal analysis, scanning electron microscopy and energy dispersive spectroscopy analysis. Amount of available plant nutrients have been determined by ultraviolet‑visible spectroscopy and inductively coupled plasma optical emission spectrometry. Subsequently, the growth course, germination and yields of selected crops were monitored. It was verified that the material based on recycled brick enriched with nutrients improves the distribution of nutrients in the soil and positively affects the germination, growth and yields of tested crops.
