Özet
Rising food demand increases fertilizer use, but phosphorus resources are limited. This study produced alternative base fertilizers from poultry litter incineration ash (PLIA) and waste sheep wool (SW). The structural and functional properties of PLIA–SW-based fertilizer (W-Ash) and PLIA–Urea-based fertilizer (U-Ash) were analyzed using X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR), and their effects were compared with those of di-ammonium phosphate (DAP: 18–46-0) in two consecutive maize experiments. Fertilizer applications significantly increased plant weights compared to the control. In the first experiment, plant N content increased from 551 mg plant−1 in the control to 1205 mg plant−1 with DAP, 1106 mg plant−1 with W-Ash, and 1055 mg plant−1 with U-Ash. Plant P content increased from 41 mg plant−1 in control to 164, 138, and 118 mg plant−1 with DAP, W-Ash, and U-Ash, respectively. In the second experiment, residual fertilizer effects significantly increased N and P contents compared with the control, while DAP no longer differed from W-Ash and U-Ash in P content. Potassium content was highest with W-Ash in the first experiment, while U-Ash and control treatments showed the highest values in the second. All fertilizers increased Ca, Mg, S, and Fe compared to the control. Unlike DAP, which reduced Zn, W-Ash and U-Ash maintained Zn above control levels. The study demonstrated that W-Ash and U-Ash, produced entirely from waste materials, were at least as effective as DAP in supporting maize growth and nutrition. These promising results warrant further testing on different crops and soil types.
