A pot study was conducted in the Department of Soil Sciences and water resources, College of Agriculture, university of Al-Qadisiyah, during the agricultural season of 2017-2018 according to the design Completely Randomized Design (C.R.D).Four levels of phosphate fertilizer P0, P1, P2, P3 (0, 30, 60 and 90) kg P. h1- and one level of sulfuric fertilizer (agricultural and wettable) Sa and S (200) kg S.h1- were used. The corn seeds of DKC 6120 cultivar were planted on 15/7/2017. Available phosphorus in the soil was estimated during plant growth periods (40, 70, and 100) days of planting to study the effect of its application levels, sulfuric fertilizer application (agricultural and wettable) fertilizers and their overlap on the amount of available phosphorus into the corn rhizosphere. Results presentthat the highest amount of the available phosphorus is achieved with the third phosphate level P3 (42.83, 31.63, and 27.21)µg.g-1 in the rhizosphere area. Out of the rhizosphere, SP3, P3 and P3 quantities result (50.03, 37.58 and 29.46) µg. g-1 soil of dates of 40, 70 and 100 days of planting, respectively. Application of agricultural sulfur itself decreases the amount of available phosphorus as compared to the control. SaP0 application level of sulfur fertilizer resulted in the lowest amount of available phosphorus (10.73, 9.84 and 7.63) µg. g1- in the rhizosphere and (11.90, 10.51, 9.25) µg. g1- in the outside the rhizosphere at (40 and 70 and 100) days of planting dates, respectively.
