Effect of unconventional phosphorus sources and phosphate solubilizing bacteria on fractions of phosphorus in a calcareous soil cultivated with wheat plants

A pot experiment was conducted at the experimental farm of Faculty of Agriculture, Ain Shams University, Egypt. To study the effect of recycling fish bone and bone meal as well as rock phosphate in a comparison with the ordinary superphosphate on the fractionation and availability of phosphorus in a calcareous soil. These treatments combined with or without adding specific bacteria. Wheat plants were grown under these treatments and their combinations to evaluate the residual effect of such treatments compared to the control (without any treatment) under different physiological stages of grown plants. Generally, the non-traditional phosphorus sources could succeed to substitute the ordinary superphosphate, as a source of phosphorus for soil and wheat plants, especially with addition of specific P-dissolving bacteria. The treatments of ½ OSP+FB and FB alone with adding P solubilizing bacteria were the best, which gave an acceptable results for the availability and fractions of P in the studied calcareous soil, more than giving a vigor plant growth compared with the other treatments. It means that recycling house wastes such as these unconventional P sources can replace with the traditional P sources without any contamination to the soil and growing plants with heavy elements, considering them environmentally friendly.
