| Abstract | ||||
| Laboratory experiment was conducted to study the effect of single or dual inoculations of association nitrogen fixed bacteria (Azosperillum Lipoferum) and Phosphate dissolved bacteria (Bacillus Polymyxa) which were isolated and identified in microorganism lab., soil department, Agriculture college at Basrah University with full dose(300 Kg.ha-1) of mineral nitrogen as urea (46%N) and 50Kg.ha-1 as super phosphate (47%P2O5) on some physical, chemical and biological properties of sandy loam soil from Al-Barjessia station in Al-Zubeir city, Basrah, Iraq, which was planted With corn seeds of Zea mays L. crop and was irrigated for field capacity with tap water during that, bacterial inoculations soil were added as broth nutrient at initial 1.8*108CFU.gm-1 at 10 ml. for 15 days of planting period (two months). After that height of plants were determined then were harvested and determined the dry weights of shoots, total numbers bacterial , soil aggregates stability, water content, bulk density, total porosity, saturated hydraulic conductivity and some soil chemical properties like PH, EC. The results showed that high significant effect for dual inoculations which promoted with full dose of nitrogen and phosphorus, (treatment ABNP) on these parameters like total numbers bacterial, mean weight diameter as index for aggregates stability, total porosity, saturated hydraulic conductivity, and water content whic | ||||
