Abstract
The experiment has been carried out in the department of soil sciences and water resources, college of agriculture, university of Al-Qadisiyah, during the agricultural season 2017-2018 by using the design Complete Randomized Design (C.R.D). The experiment in pots has used four levels of phosphate fertilizer P0, P1, P2, P3 (0, 30, 60 and 90) kg P. h1- respectively and one level of sulfuric fertilizer (agricultural and wettable) Sa and S (200) kg S.h1-. Maize seeds of DKC 6120 variety have been in plastic pots grown. Dissolved phosphorus in the soil is 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 dissolved phosphorus into the corn rhizosphere. Results show that the highest amount of dissolved phosphorus in and out of the rhizosphere soil obtained with application of the phosphate level P3 (90) kg P. h1- which were (0.69, 0.58, 0.55) μg. g1- and (0.75, 0.63, 0.59) μg. g1- for the soils of the rhizosphere and beyond respectively during the periods (40, 70 and 100) days of planting.
