“…In their studies on the availability of Zn, Cu, Fe, Mn in soils, Sidhu and Sharma (2010) have reported that the total content of these micronutrients increased with an increase in clay and silt and CEC, whereas the DTPA-extractable levels decreased with increasing pH and calcium carbonate content. Similar data have been reported by Mathur et al (2006), who showed that DTPA Zn correlated among others significantly and negatively with pH (r = −0.383), but positively with organic carbon (r = +0.738).…”

“…Micronutrients soluble in aqua regia were determined by atomic absorption spectrometry (AAS) (Varian SpectrAA 250 plus, Germany) and considered as a total metal content. Next, active and potentially mobilisable micronutrient forms were extracted by the 0.005 moles diethylene triamine pentaacetic acid (DTPA) dm -3 , pH 7.3, test suggested by Sidhu and Sharma (2010). Ten grams of appropriate soils were mixed with 20 cm 3 of 0.005 moles dm -3 DTPA, pH 7.3 (weight:volume -1:2) for two hours, the extraction proceeded as described above.…”

Investigations were undertaken on an agricultural farm (52 ha) located at the Wielkopolska region, Western Poland. Soil samples (294) were collected at 0-30 cm depth from 6 fields after harvesting of winter triticale, winter wheat, winter barley, grass mixtures, winter oilseed rape and sugar beet. The following properties were determined: silt and clay, organic carbon (C org ), pH (in 0.01 moles CaCl 2 dm -3 ), cation exchange capacity (CEC). Copper (Cu), zinc (Zn), iron (Fe) and manganese (Mn) were extracted by aqua regia test (total content) and 0.005 moles diethylene triamine pentaacetic acid (DTPA), pH 7.3 (active and potentially available forms). Potential availability and soil physical as well as chemical changes of these micronutrients were evaluated by using availability factors and thermodynamic parameters (Gibbs free energy change, ∆G°). Data show that 83% of all tested soil samples were characterised by C org < 25 g kg -1. Moreover, the variability in pH was very high (4.7 < pH CaCl2 > 7.8), ca 1/6 of investigated soils (16%) were acid, but on the other hand, 82% exhibited pH > 5.5. The mean CEC value amounted to 12.0 cmol (+) kg -1 , with 71% of soils representing CEC < 12.0 cmol (+) kg -1. In fact, the range 12.0 ≤ CEC ≥ 25.0 cmol (+) kg -1 , designating moderate buffering properties, shared ca 55%. The DTPA-based availability factor (AF) followed the order Zn > Cu > Fe > Mn, with respective indices 22.9 > 19.8 > 5.5 > 0.42. Next, linear relationships established for the pairs C org vs DTPA Cu,Zn,Fe,Mn resulted in the following correlation coefficients (r): C org vs DTPA Cu , r = 0.67**; C org vs DTPA Zn , r = 0.60**; C org vs DTPA Fe , r = 0.56*; C org vs DTPA Mn , r = 0.50*. It appeared that in the case of increasing or decreasing pH, the reactions of Cu, Mn and Fe in the soil solution should be similar, i.e. progressive unavailability or progressive availability, respectively. Thermodynamic changes (ΔG° values) calculated for Zn, Cu, Fe and Mn were the basis for establishing the following operational ranges: −5.0 ≤ ∆G°, readily available (for Zn); −5.0 ≥ ∆G° ≥ −10.0, moderately available (for Cu); −10.0 ≥ ∆G° ≥ −15.0, slightly available (for Fe); ∆G° ≤ −15.0, hardly available (for Mn). The ∆G°-based values showed that micronutrient availability criteria should not be restricted to quantitative evaluation only.

“…On the other hand, the availability of zinc was reduced significantly with an increase in CaCO 3 (r = -0.718**) and pH (r = -0.618**) of soil. Sidhu and Sharma (2010) also reported that the available micronutrients (Zn, Cu, Mn and Fe) increased with increase in organic carbon and decreased with increase in sand content, pH, and calcium carbonate.…”

“…Singh (2008) also reported that the analyzed of soil and plant samples had indicated that 49 per cent of soils in India are potentially deficient in Zn, 12 per cent in Fe, 5 per cent in Mn, 3 per cent in Cu, 33 per cent in B. Later on, Sidhu and Sharma (2010) reported that the DTPA-extractable Zn in Trans-Gangetic Plains ranged from 0.11 to 5.08, Cu ranged from 0.22 to 4.72, Mn ranged from 2.9 to 101.2, and Fe ranged from 1.05 to 97.9 mg kg -1 . In the Upper Gangetic Plains, the DTPA-extractable Zn ranged from 0.04 to 2.53, Cu ranged from 0.06 to 4.32, Mn ranged from 11.1 to 421.0, and Fe ranged from 3.48 to 90.2 mg kg -1 .…”

The aim of this study was to evaluate available micronutrient (Fe, Cu, Zn, Mn and B) status and their relationship with soil properties. To study this, there were seventy surface soil (0-30 cm depth) and plant samples, each collected from wheat growing fields of Jhunjhunu tehsil. The soils were analyzed for physico-chemical properties and status of available micronutrients. Grain and straw samples of wheat plant separately analyzed for micronutrient contents. The sand, silt and clay content of the soil ranges from 76.70 to 90.40, 1.30 to 7.50 and 5.20 to 12.90 per cent, respectively and these soils categorized as sandy, loamy sand and sandy loam. The soils were moderately calcareous in nature and having CaCO 3 content ranges from 3.90 to 12.00 per cent. The analyzed samples showing lower in organic carbon and CEC and their ranges from 0.06 to 0.43 per cent and 2.40 to 10.40 cmol (p + ) kg -1 , respectively. The pH (8.10 to 9.20) and EC (0.20 to 2.14 dSm -1 ) values indicated that soils were found to be moderately alkaline and non-saline in nature. The 90 per cent of analyzed soil samples were found to be deficient in iron and 70 per cent deficient in zinc and their values ranges from 1.22 to 5.87 and 0.12 to 1.30 mg kg -1 , respectively. While the remaining micronutrients (Cu, Mn and B) shown to be sufficient and their values ranges between 0.17 to 3.32, 2.03 to 5.67 and 0.37 to 1.51 mg kg -1 , respectively. The availability of micronutrients indicating positive and significantly correlated with silt, clay, organic carbon and CEC of soils, whereas, negative and significantly correlated with sand, calcium carbonate and pH of the soils. The availability of micronutrients in wheat grains and straw positively correlated with silt, clay, organic carbon and CEC and negatively correlated with sand, CaCO 3 and pH of soils.

“…Such conditions could occur in B landfills where in the low pH content of available forms of analyzed heavy metals was lower than in C. However, in the case of zinc and copper availability factor (AF) was the highest and reached 46.27% for zinc and 78% for copper (Table 5). In their studies on the availability of selected heavy metals in soils, Sidhu and Sharma (2010) have reported that the total content of these micronutrients increased with an increase in clay and silt, whereas the DTPA-extractable levels decreased with increasing pH and calcium carbonate content. Similar data have been reported by Mathur et al (2006) who showed that DTPA Zn correlated among others significantly and negatively with pH, but positively with organic carbon.…”

The aim of the study was the assessment of the environmental contamination of soil by heavy metals and microorganisms within the uncontrolled landfill dumps and the impact of anthropogenic sources on the activity of selected soil surface horizons. Some physicochemical properties were determined according to commonly used procedures in soil science laboratories. The total of heavy metals concentration was assessed according to Crock and Severson and forms available according to Lindsay and Norvell. The total contents and mobile forms were determined by atomic absorption spectrophotometry. As part of the microbiological tests, potentially pathogenic evidence of bacteria was found indicating fecal contamination of the soil (E. coli and other coliform bacilli, Salmonella spp., and Enterococcus spp.). Quantitative analyses were carried out based on the calculation of the most probable number of microorganisms (MPN method). The activity of selected redox and hydrolases enzymes: the activity of dehydrogenases with the Thalmann method, catalase with the Johnson and Temple method, alkaline and acid phosphatase with the method of Tabatabai and Bremner. It was concluded that depending on the composition of the dump, the physicochemical properties of the soil were changed, too. Uncontrolled landfills significantly affected the increase or decrease in the pH of the tested soil and the organic content of the tested soil. The waste stored at the site affected the contamination of the soil by heavy metals to varying degrees. The results show that the most dangerous bacteria exist in the soil under the C landfill and this is where the greatest risk of soil contamination exists. The highest amount of selected enzymes activity was observed in soils under illegal C dumping sites. In the soil sourced from A and B landfills, the enzyme inhibition occurred which was linked to the lowering of the organic carbon. The results of the principal component analysis demonstrated that the content of heavy metals and the activity of enzymes are the indicators of anthropogenic pollution, whereas granulometric composition (sand and silt) is mainly associated with the natural environment.
