“…Tensile tests were carried out using an instrument for testing different materials (Texture Analyzer XT2) and tensile properties were determined using Texture Expert Software (Texture Technologies Corp., Scarsdale, NY, 2005 (Mehlich 1984). Easily leachable Zn was extracted with the BaCl2 reagent according to Schultz et al (2004), which is a modified version of Normal ISO 11260 (1994). This procedure consisted of weighing a 3 g soil sample in a 125 mL conical glass flask and extracting the leachable Zn with 30 mL of 0.01 M BaCl 2 reagent for 2 h at 260 rpm.…”

“…These bonds determine, to a large extent, the bioavailability of the metals, although biological uptake mechanisms may contribute to a varying degree. Chemical bonds may change over time due to abiotic processes such as changes in temperature and redox conditions, or microbial activity, resulting in varying availability to other organisms (Schultz et al 2004). …”

The relationships among soil microbial biomass, pH and available of heavy metal fractions were evaluated in longterm contaminated soils during an incubation experiment with the amendment of zeolite (natural clinoptilolite) and the subsequent addition of glucose. The values of pH a�er the addition of glucose decreased during the first day of incubation approximately at about one unit and corresponded with the maximum increase of microbial biomass. The available heavy metal contents extracted by H 2 O, 1 mol/l NH 4 NO 3 and 0.005 mol/l DTPA increased during the first two days of incubation. Only a few significant relationships were found between the available metal contents and pH or microbial biomass. This fact could be ascribed to the different dynamics of the microbial biomass, pH and metal availability a�er glucose addition, when the highest metal contents during the incubation were usually reached one day later in respect to the greatest changes of pH and microbial activity. In comparison to soils without zeolite addition, the variants with natural clinoptilolite showed lower heavy metal contents in all used extractants with the exception of Cd which in H 2 O extracts tended to increase.

“…One approach for estimating Zn availability to plants is to use single extractions as with the DTPA-ammonium bicarbonate (DTPA-AB) method (Soltanpour, 1991); this tends to correlate well with metal concentrations in plants (Adriano, 2001;Alvarez, 2007). In addition, according to Schultz et al (2004) the easily leachable Zn could be estimated by the BaCl 2 reagent. Another approach for diagnosing soil-Zn sta-3 Effects of synthetic Zn chelates on flax response and soil Zn status the manufacturers´ recommendations for different Zn fertilizers.…”

“…Easily leachable Zn was extracted with the 0.01 mol/L BaCl 2 reagent according to Schultz et al (2004) [the supernatant was filtered by vacuum pump, with a 0.45 µm cellulose acetate membrane filter (Albet 47BL, Barcelona, Spain)]. Soil pH, redox potential [E h , pe = E h (mV)/59.2] (ISO 11271, 2002) and electrical conductivity were measured in deionized water at a 1:2.5 (w:v) soil:water ratio.…”

Throughout the world, flax (Linum usitatissimum L.) is often grown in Zn-deficient soils, but appropriate fertilizer management can optimize both crop yield and micronutrient content. A greenhouse experiment was conducted on Typic Haploxeralf (pH 6.1) and Typic Calcixerept (pH 8.1) soils to study the relative efficiency of chelated Zn using two application rates of three different Zn sources [Zn-EDDHSA, ethylenediamine-di-(2-hydroxy-5-sulfophenylacetate of Zn); Zn-HEDTA, N-2-hydroxyethyl-ethylenediaminetriacetate of Zn; and Zn-EDTA, ethylenediaminetetraacetate of Zn]. Dry matter /DM) yield, Zn concentration, chlorophyll content, crude fiber and tensile properties were monitored and the soil-Zn status (available-Zn, Zn-fractions and total-Zn) was assessed. Zinc chelate applications increased the most labile forms of Zn in soils and Zn concentrations in plants. The low rate of Zn generally had a beneficial effect on DM yield and tensile properties. The exception was Zn-EDTA in the weakly acidic soil, where the highest Zn concentrations were observed in leaves and whole shoots; this coincided with the largest concentrations of labile Zn in soil. The most efficient fertilizers were Zn-EDDHSA (in both soils) and Zn-EDTA (in the calcareous soil). The relatively large amounts of labile and available Zn present in both of the soils fertilized with Zn-EDTA points to the applying this chelate at lower rate than 5 mg Zn/kg; this should, in turn, reduce the cost of Zn fertilization and minimize environmental pollution risk.
