The study focused on investigating the contribution of reclamation strategies saline-sodic soils and their impacts soil fertility characteristics. In this study, treatments were denoted as: SG1 SG2 (23.8 47.7 ton/ha spent grain); TC1 TC2 47.6 compost); Azospirillium in inoculation with seed (Az); Az + (Az+SG1); (Az+TC1); mineral fertilizers (NPK); control (CK). All mixed pots 30 kg soil. result...
In this study, an integrated in situ remediation technique which couples electrokinetics with adsorption, using locally produced granular activated carbon from date palm pits in the treatment zones that are installed directly to bracket the contaminated soils at bench-scale, is investigated. Natural saline-sodic clay soil, spiked with contaminant mixture (kerosene, phenol, Cr, Cd, Cu, Zn, Pb, a...
Sodic amphiboles in high pressure and ultrahigh pressure (UHP) metamorphic rocks are complex solid solutions in the system Na2O±MgO±Al2O3±SiO2± H2O (NMASH) whose compositions vary with pressure and temperature. We conducted piston-cylinder experiments at 20±30 kbar and 700±800 °C to investigate the stability and compositional variations of sodic amphiboles, based on the reaction glaucophane 2...
The ~1.08 Ga anorogenic, A-type Pikes Peak batholith (Front Range, central Colorado) is dominated by coarsegrained, biotite±amphibole syenogranites and minor monzogranites, collectively referred to as Pikes Peak granite (PPG). The batholith is also host to numerous small, late-stage plutons that have been subdivided into two groups (e.g. Wobus, 1976. Studies in Colorado Field Geology, Colorado ...
Eastern Birjand ophiolitic complex consist of different rock types of a complete ophiolitic sequence. Three groups of amphiboles which exist in metabasites of this ophiolitic complex are of: calcic amphiboles, such as actinolite-tremolite and magnesio-hornblende; calcic-sodic amphiboles, e.g. vinchite and barroisite; and sodic-amphiboles, e.g., glaucophane, magnesio-riebeckite and ferro-glaucop...
ویژگی های زمین شیمیایی، کانی شناسی، و میکرومورفولوژیکی خاک ها و سنگ مادر مربوطه در منطقه بین بخش های جنوبی زاگرس و خلیج فارس تا دریای عمان(استان هرمزگان، ایران) مورد بررسی قرار گرفت. هدف های این مطالعه شناسایی تغییرات در خصوصیات فیزیکی، شیمیایی، و ترکیب کانی شناسی خاک، مطالعه میکرومورفولوژی و تکامل خاک، و بررسی توزیع عنصر خاک بر اساس هوازدگی، پروسه های خاک و زمین شناسی جهت توصیف اثرات مواد مادر...
Consistent use of high RSC water may deteriorate the physical properties of soil and increases pH and SAR of soil. Continuous use may reduce germination / the establishment of seedling, retards plant growth and leads to a significant reduction in yield. Therefore, a field experiment in microplots was displayed at research plot in St. John’s College, Agra to study the effect of sodic water on th...
