The temporal response of bacterial community, especially that bacteria with Fe(III) reducing ability, in flooded paddy soils to initial pH changes, is not well-documented. This work demonstrated variations concentration Fe species, activity and community succession shift acidic or alkaline level. causal links shift-induced reduction was also assessed. Results showed soil shifts greatly influenc...

The northeast region of Birjand is located in Lut structural and geological province. In this area we can distinguish two separate volcanic rock groups: intermediate to acidic volcanic rocks, including dacite, andesite, rhyolite and trachyandesite; and basic rocks, including basaltic andesite, mugearite and basalt. In this region, intermediate to acidic rocks, which belong to the Eocene-Miocene...

-Plant roots and soil organisms increase phosphorus availability by releasing acid and alkaline phosphatase. Organic phosphorus compounds are hydrolysed into plant-available forms through the action of these enzymes. Phosphatase is of particular importance under conditions of low phosphorus availability which is commonly found in pinon-juniper soils. Acid and alkaline phosphatase activities (mg...

Adoption of crop residue amendments has been increasingly recommended as an effective management practice for mitigating greenhouse gas emissions while enhancing soil fertility, thereby increasing production. However, the effect biochar and straw on nitrous oxide (N2O) methane (CH4) in soils differing pH remains poorly understood. Three treatments (control (i.e., no amendment), maize straw, der...

Biochar, an alkaline carbonaceous substance resulting from the thermal pyrolysis of biomass, reportedly enhances micronutrient availability in acidic soils with little or no effect on soils. In this study, biochars were produced poultry manure (PM) at 350 °C and 550 (BC350 BC550 respectively). The acidified (ABC350 ABC550, respectively) incorporated into sandy soil, their effects soil micronutr...
