Two field experiments were conductedunder surface irrigation system during two successive winter growing seasons 2017/2018 and 2018/2019in private farm atEl Qantra-West, Ismailia Governorate,Egyptto evaluate the effect of combinations three levels phosphorus fertilizer (0, 15.5 31.0 kg P

Returning straw to the field is an effective method for optimizing soil phosphorus (P) availability, in which bacteria play important role. However, effects of various incorporation strategies on P transformation between different pools remain unclear. In this study, variations fractions, phosphatase activities and abundance genes (phoD, phoX phoC) as well a P-solubilizing gene (pqqC) at DNA (t...

The interactive effect of phosphate-solubilizing bacteria and arbuscular mycorrhizal (AM) fungi on plant use of soil P sources of low bioavailability (endogenous or added as rock phosphate [RP] material) was evaluated by using soil microcosms which integrated (sup32)P isotopic dilution techniques. The microbial inocula consisted of the AM fungus Glomus intraradices and two phosphate-solubilizin...

This paper reports a study of the effect of three nuclear and one thermal power plants on the microbial ecology of soils. Populations of bacteria, actinomycetes, fungi, cellulolytic microbes, phosphate-solubilizing microbes and nitrogen-fixing microbes in the soil in the vicinity of each plant were studied. Soils were acidic at three sites, and moisture contents of the power plant soils were lo...
