Abstract

After nitrogen, between the essential nutrients, phosphorus is the most important limiting factor in agricultural yield production in the world. There are different methods for assessing the phosphorus status in soil and water. One of the new techniques in this regard is diffusive gradient in thin films (DGT) techniques. This method based on the ion transport in a diffusion layer and its absorption by a resin layer. In manufacturing the gels in DGT, the material used is monopolies and patented. In this study, acrylamide - alyl agarose gel was used as the diffusion layer and ferryhydrite in acrylamide - alyl agarose gel as the resin layer in DGT assembly and the effect of diffusion coefficient in diffusive gel, diffusive gel reactivity, and phosphorus desorption kinetics from resin gel, phosphorus recovery efficiency from the resin gel and DGT performance in soil and water were examined. The results showed that the diffusion coefficient of phosphorus ions in the gel with a 0.3% of alyl agarose at 25 °C was 8.2×10-6 cm2/s and decreased with increasing alyl agarose concentrations. Phosphorous recovery efficiency from resin gel measured by 10 ml H2SO4 0.15 M was almost 100 percent. The measured P using DGT, showed a strong linear correlation (r=0.98**) with the phosphorus concentration in the examined solution. In this study, an excellent correlation (r=0.99**) between the P measured by DGT and the available P measured by the traditional Olsen method were observed in three calcareous soils, implying that DGT may be a suitable alternative method for rapid available P measurement in calcareous soils.
