Abstract

Turkey’s soils are generally alkaline and calcareous. Approximately 70-90% of the phosphorus applied to the alkaline and calcareous soils phosphorus (P) becomes unavailable forms by plants. Therefore, there is a need for forms of fertilizer that can provide greater uptake of phosphorus fertilizers by plants. However, there is not enough study about the effect of organomineral fertilizer and chemical fertilizer applications on the soil P content. The aim of this study was to determine the effect of chemical (DAP; 18% N, 46% P2O5) and organomineral (OMG; OM 15%, N 8%, P2O5 20%, SO3 10%, 10% Humic + Fulvic acid) on available P in soils. The experiment was designed as a randomized plot design with three replications. Soil samples were taken on 1, 15, 3, 60, 90. Days, and the available P contents were determined in soils. According to the obtained data, the high average available P content of the soils was obtained in the samples taken on the 1st day and the lowest on the 90th day. The available P content in the soils decreased with by the time. The effect of fertilizer forms (OMG and DAP) on the average available P content of soils was statistically significant at p <0.01 level. When DAP fertilizer and OMG fertilizer were compared, depending on time the available P contents of the soils were 16-21% higher in OMG fertilizer applications. However, detailed studies in different ecologies are needed.
