    Abstract

    Cultivation systems used for rose production often impose salt stress in arid and semiarid regions of the world. While boron (B) has been widely reported as a nutrient that can alleviate the adverse effects of salt stress on crop growth and yield, inadequate information is available regarding the emerging pattern of rose plant responses to an appropriate concentration of boron under salinity condition is available. To address this issue, an experiment was conducted to evaluate the effects of different levels of B application (24, 34, 44, and 54 μM) on Rosa plants under two levels of salt stress (1.8 and 2.9 dS m−1). Cut rose (Rosa hybrida L.) “Dolce Vita” was grown hydroponically in containers with a mixture of cocopeat and perlite

    Journal PapersChemosphere , 2020 April 4, {Pages 126691 }

    Abstract

    Low redox potential in flooded soils may affect phosphate bioavailability by reducing iron oxides or formation of new minerals. To investigate phosphate behavior in anoxic conditions, goethite was selected as a soil model and coated by humic acid (HA) and sodium borohydride was used as a reducing agent. Adsorption experiments were conducted in 0.1 M NaNO3 as a function of pH in oxic (Eh?=?+254 to +448?mV) and suboxic (Eh?=?−162 to +167?mV) conditions for four phosphate concentrations (0.05–0.8?mM). CD-MUSIC and NOM-CD models in combination with Extended Stern model were used to describe the experimental data. Results show that by increasing pH and carbon content in the organo-mineral composites, the released phosphate to the solution

    Journal PapersLand Degradation & Development , 2020 March 30, {Pages }

    Abstract

    Due to imbalanced groundwater withdrawal, Mg concentration has relatively increased in the majority of irrigation waters in arid and semiarid regions, which may negatively affect soil properties and productivity. Therefore, this study was aimed at understanding to what extent varying Ca to Mg ratios in the calcareous soil solution alter the ratio on the exchangeable sites. To do so, four calcareous soils were equilibrated with eight Ca to Mg ratios and then the relative adsorption of Ca and Mg ions on the exchangeable sites and the CEC of soil samples were measured using a modified silver‐thiourea method. To quantitatively explain our observations, we used the Gaines–Thomas equation, and its parameters were independently derived from t

    Abstract

    Calcite, the most stable calcium carbonate in soil, is a major part of soil solid phase in arid and semiarid regions. This mineral significantly affects the chemical behavior of ions including oxyanions and transition metal ions in the soil. Arsenate and phosphate are two important oxyanions in natural systems like soil and because of similar ionic properties strongly compete for the colloids surface charge via adsorption and desorption reactions. Because of the importance of this reaction in controlling the equilibrium concentrations of arsenate and phosphate in soil, in this research, arsenate adsorption on calcite was measured and modeled as a function of arsenate concentration and ionic strength and also in competition with phosphate. I

    Abstract

    This study investigated the effects of exogenous methionine (Met) and different phosphate (PO4) concentrations on Cd uptake and translocation in Valeriana officinalis L. Seedlings were grown in nutrient solutions with three different concentrations of phosphate (900, 1200, and 1500?μM) for two weeks, then exposed for 4 days to 10?μM Cd, either in presence or absence of 400?μM methionine. The Met treatment decreased root Cd accumulation by up to 40%, while it enhanced Cd uptake into the shoots by 50%. In absence of Met, shoot Cd uptake was not affected by the level of phosphate application, although root Cd contents increased. The latter effect was entirely due to increased apoplastic Cd binding. In presence of Met, the Cd accumulation of

    Abstract

    Boron (B) is highly mobile in the environment. This characteristic easily leads to plant deficiency upon leaching from soil or to toxicity upon accumulation. Boric acid may interact with mineral surfaces as well as natural organic matter. In this study, the boric acid interaction with humic acid (HA) was measured in 0.01 M NaCl and CaCl2 background solutions as a function of pH and the initial B concentration. In the Na-HA suspensions, the free boric acid concentration was determined using a novel approach, applying the Donnan Membrane Technique (DMT) in the dynamic mode. In the method, the experimental rate of diffusion is used as a measure for the free boric acid concentration. B adsorption in Na-HA and Ca-HA systems can be described wi

    Abstract

    Rose production is a function of the genetic traits and environmental characteristics, including quantity and quality of the irrigation water. Due to the limitation in availability of high quality water resources in most regions of Iran, the effect of electrical conductivity of irrigation water (due to variation in sodium chloride concentration) was investigated on the yield and quality of rose cv. Dolce vita in hydroponic system. The experimental treatments included four nutrient solutions with different electrical conductivities of 1. 6, 1. 8, 2. 0 and 2. 2 dS m-1 containing 3. 18, 4. 57, 5. 69 and 6. 87 mM sodium and 1. 58, 2. 71, 3. 76 and 5. 11 mM chloride concentrations, respectively. Results indicated that treatments not only had no

    Abstract

    Introduction&58; Natural environments, including soils and sediments, are open and complex systems in which physico-chemical reactions are in semi equilibrium state. In these systems, bioavailability of plant nutrients, like phosphate, is influenced by environmental conditions and concentrations of other ions such as calcium and magnesium. Magnesium is a dominant cation in irrigation water and in the soil solution of calcareous soils. Recent evidences show relative increase in the concentration of magnesium in irrigation water. Because of the importance of chemical kinetics in controlling concentrations of these ions in the soil solution and for understanding their effects of adsorption kinetics of magnesium and phosphate ions, in this rese

    Journal PapersChemical Geology , Volume 437 , 2016 October 25, {Pages 19-29 }

    Abstract

    In natural environments, competitive interactions of ions with charged particles often control bioavailability and mobility of ions. In these systems, chemical reactions are often in a semi-equilibrium state; thus, along with equilibrium data, kinetic data are of great importance in predicting ion bioavailability and mobility. Therefore, in this research, kinetics and equilibrium adsorption interactions of magnesium, calcium and phosphate on goethite are investigated as a function of time, pH, ion loading and ionic strength in single and binary ion systems. The thermodynamically valid model parameters, obtained from single ion systems by applying the CD-MUSIC model, are used to predict ion interactions in more complex systems, i.e. binary i

    Abstract

    The objective of this study was to study the influence of different ethylenediamine tetraacetate (EDTA), nitrilotriacetic acid (NTA) and oxalic acid (HOx) concentrations on tolerance and lead (Pb) accumulation capacity of carrot (Daucus carota). The results indicated that by increasing Pb, NTA and HOx concentrations in the soil, the shoot, taproot and capillary root dry matters increase effectively. In contrary, EDTA caused to reduce capillary roots biomass. EDTA was more effective than NTA and HOx in solubilizing soil Pb. The highest Pb content in shoots (342.2???13.9?mg?kg−1) and taproots (301???15.5?mg?kg−1) occurred in 10?mM EDTA, while it occurred for capillary roots (1620???24.6?mg?kg−1) in 5?mM HOx, when the soil Pb concentrati

    Abstract

    Investigating the interactions of heavy metals is imperative for sustaining environment and human health. Among those, Cd is toxic for organisms at any concentration. While Ni acts as a micronutrient at very low concentration but is hazardous toxic above certain threshold value. In this study, the chemical adsorption and desorption reactions of Ni and Cd in contaminated soils were investigated in both single and binary ion systems. Both Ni and Cd experimental data demonstrated Langmuir type adsorption. In the competitive systems, an antagonistic effect was observed, implying that both ions compete for same type of adsorption sites. Adverse effect of Cd on Ni adsorption was slightly stronger than that of opposite system, consi

    Abstract

    Understanding the processes that control the activity of boron (B) in the soil solution is important for maintaining water quality and soil fertility management. Since these processes are influenced by the physical and chemical properties of soil, in this research, the effects of soil properties on B adsorption-desorption reactions and the degree of reversibility were studied. For this purpose, B adsorption and desorption isotherms were measured in 14 calcareous soils. Adsorption isotherms were described by using the empirical models and the effects of soil properties were analyzed by using the multi-variables regression. Results showed that B adsorption followed Langmuir equation with maximum adsorption in the range of 3-14 mmol. kg-1. Cal

    Abstract

    Soil contamination is one of the most recent and important environmental challenges worldwide. The so-called phytoremediation is one of the reclamation technologies used to decontaminate polluted soils. Application of some chelate agents can increase the efficiency of phytoremediation. However, this technology has not been evaluated for decontamination of heavy metals under multicropping system. The objective of this study was to evaluate the phytoremediation capability of cress and radish, as a mixed-culture by using some natural and synthetic chelates in Cd-contaminated soils. Consequently, a factorial experiment in a completely randomized design with 20 treatments and three replications was conducted. The experimental factors were consis

    Abstract

    Soil contamination by heavy metals, due to human activities, is not often limited to a single contaminant. The objective of this study was to develop a simple model for phytoextracting separate and combined Ni and Cd from contaminated soils. The study was further aimed to study phytoextraction potential of ornamental kale and land cress grown in soils contaminated with separate and combined Ni and Cd metals. The results indicated that elevated Ni and Cd concentrations in soil inhibit growth of both ornamental kale and land cress plants. In Ni + Cd treatments, growth and development of both plants were more affected than in either Ni or Cd treatments. Further, in Ni + Cd treatments, Ni concentration in tissues of both

    Abstract

    Nitrate anion is an important ground- and surface-water contaminant, around the world. High nitrate concentration could damage the human respiratory and digestive systems; thus, controlling nitrate transfer toward water resources and reducing its concentration is essential to protect human health and the environment. In this research, effect of coating zero-valent iron nanoparticles on quartz (Q-Fe0Nps) and possible retrieving and reusing them were evaluated for removing nitrate from aqueous solution. Fe0Nps were made by chemical reduction method and supported by quarts. Fe0Nps efficiency for removing nitrate was assessed in both equilibrium and fluid systems as function of nitrate and Fe0 concentrations. Results indicated that in appropria

    Abstract

    Colloidal particles prevalent in a soil influence its chemical and physical properties as by the particles' surface electrical charges. With respect to the importance of the issue, from both agriculture and environmental points of view, charging behavior of a kaolinite soil sample was studied in the pH range of 4 to 10 and at three background electrolyte concentrations of: 0.005, 0.05, 0.5 M NaCl, by potentiometric titration. Using a combination of mass and electrolyte titrations, kaolinite point of zero charge (PZC) was determined to occur at pH= 7.6. Increase in pH from the initial value of 4 caused at first a gradual decrease in positive surface charge and then a gradual increase in the negative surface charge, indicating a net positive
