Title: Characteristics of phosphate rock powder and its fertilizer efficiency
Abstract: The chemicophysical properties and fertilizer efficiency of the superfine phosphate rock powder was studied through indoors simulation analysis and pot experiment.The results indicated that the diameters of the superfine phosphate rock powder were 7.26 μm、 4.06μm,and the available phosphorus content increased significantly;the pot experiment indicated that superfine phosphate rock powder could promote the growth of corn and increased the utilization rate of phosphorus,the significant difference existed between the ordinary phosphate rock and the superfine phosphate rock powder;superfine phosphate rock powder could increase the content of available phosphorus in soil compared with ordinary phosphate rock.
