The present study aimed to evaluate the effectiveness of organomineral fertilizers, which have become widespread in recent years. For this purpose, a pot experiment under greenhouse conditions was carried out to show the effect of nitrogen (N), phosphorus (P), and potassium (K) applied together or separately with an organic fertilizer (OF) originating from the biogas plant on the growth and the nutrient uptake of the model plant wheat (Triticum aestivum L. cv. Adana-99). Two different fertilizer application methods (incorporating and placement) were mimicked, and the efficacy of biogas plant-derived organic fertilizers was determined. The results of the study show that the OF applied with the plant nutrients positively affected plant growth and nutrient uptake. According to the correlation analysis, significant correlations were found between the OF application and the shoot dry weights of the plants and their P uptake. The fertilizer application 5 cm below the seedbed caused the most effective results. The correlative relationships detected in plants where the OF and N, P, and K were applied together disappeared when plant nutrients were mixed to the entire pot, and OF was used 5-10 cm or 5 cm below the seedbed. The results showed that biogas facility-based OF applications, together with the plant nutrients in the form of an organomineral fertilizer, can increase the nutrient use efficiency of plants by improving their uptake, especially that of P.
