Schematic diagram of the flow of the current study. Study 1 investigated the synergism of wollastonite on plant growth and provided the optimal application rate for Study 2. Study 2 investigated the synergism of silicon release and uptake on improved produce quality. Study 3 further investigated wollastonite amendment and silicon uptake in synergism with nitrogen fertilizer. Study 3 also considered an alternate way of applying wollastonite to soil (as a fertilizer coating), achieving synergism between ease of application, fertilizer efficiency, and crop benefit.
