Transport and deposition behaviour of engineered nanoparticles (ENPs) in natural aquifers soil systems is a key determinant the fate these materials environmental systems. A growing number experimental studies are being conducted worldwide to address transport ENPs porous media (PM). Here we comprehensively review main mechanisms factors affecting mobility environmentally important PM. variety different processes including those that promote result elution from PM hinder their ENP retention...
Haloalkaliphilic bacteria have plant growth promoting characteristics that can be used to deal with different environmental stresses.To study the effect of haloalkaliphilic reduce salinity and alkalinity stress in wheat, 48 isolates were isolated grouped into halophiles, alkaliphiles haloalkaliphiles based on characteristics.The ammonia, 3-indole acetic acid ACC (1-aminocyclopropane-1-carboxylate) deaminase production studied.Wheat yield was evaluated presence six activity superior...
Zinc oxide-engineered nanoparticles (ZnO ENPs) have received the most attention in recent years. This increasing interest has been directed towards studying environmental fate and effects of ZnO ENPs on ecological terrestrial species. In this study, NPs were synthesized by atmospheric pressure solution evaporation method coated or uncoated with humic acid (HA). The root uptakes HA-coated zinc (Zn) investigated gel-grown cucumber. Two levels (1 200 µM) applied form (T3) non-coated (T2) bulk...
Abstract This study investigated the impact of monovalent cations on clay dispersion, aggregate stability, soil pore size distribution, and saturated hydraulic conductivity agricultural in Iran. The was incubated with treatment solutions containing different concentrations (0-54.4 mmol l −1 ) potassium sodium cations. included two levels electrical (EC=3 or 6 dS m six K:Na ratios per level. At both levels, spontaneously dispersible increased increasing K concentration, ratio. A negative...
Summary The role of potassium (K) in clay dispersion agricultural soils containing large concentrations K could be similar to Na. This research was carried out assess the effect sodium ratios (K:Na) on net dispersive charge, Gapon selectivity coefficient ( G ), zeta potential ζ ) and percentage dispersible clay. Different K:Na at two electrical conductivity levels (EC = 3 6 dS m −1 were added an loamy soil. results demonstrated that charge showed positive relations with concentration ratio;...
The effect of dilution on the composition soil solutions 8 contrasting soils ranging in pH from 5·3 to 8·8 with reference zinc (Zn) and copper (Cu) was studied. Soil samples were equilibrated water various water:soil ratios for 24 h. Equilibrium extracted analysed dissolved organic carbon (DOC), major minor elements. separation solution at field capacity (FC) carried out by a drainage method. Although concentration ions decreased upon dilution, total quantity sodium (Na), potassium (K), Zn,...
Abstract A study was conducted to investigate the chemical speciation of added cadmium (Cd) and lead (Pb) their availability as influenced by fresh organic matter (OM) sodium chloride (NaCl) in three agricultural soils. The soils were treated with 20 mg Cd/kg nitrate [Cd(NO3)2 · 4H2O], 150 Pb/kg [Pb(NO3)2], g/kg alfalfa powder, 50 mmol/kg NaCl then incubated for 3 months at 60% water‐holding capacity (WHC) constant temperature (25 °C). Subsamples taken after 1, 3, 6, 12 weeks incubation,...
Using saturated or enriched zeolites as slow release fertilizers (SRFs) is considered an environmental-friendly strategy to enhance use of macronutrients in sandy soils. In this paper, two natural zeolites, clinoptilolite (CLI) and chabazite (CHA) were used mineral precursors prepare NH4+/K+ (NH4+/K+-CLI) (NH4+/K+-CHA) zeolitic nutrient sources (ZNSs). Comparison between the retention capabilities these ZNSs was one main objectives study. The NH4+/K+-CLI NH4+/K+-CHA prepared by soaking NH4Cl...
The relative effects of Na + and K on soil structural stability due to application some conditioners in sodic soils are not clearly defined by the existing literature. In this research, a completely randomized design experiment was performed quantify effect physical properties loamy soil. Five treatments included no conditioner as control, urban solid waste compost (MC), Vermi-compose (VC), poultry manure (PM), gypsum powder (G). amount each amendment 10 ton/ha treatment consisted 3...
