“…Average values of Zn at MEM (entisols and vertisols) were also higher than those reported by Dabkowska-Naskret [30] in agricultural soils of the Kujawy region, Poland. Total Cu concentration in MEM soils were higher than the values presented by McLaren and Crawford for 24 British soil series that ranged from 4.4-63.5 mg kg −1 ; also the total Cu values given by Han et al [29] for vertisols of the Mississippi River Delta (41-52 mg kg −1 ) were below the information here presented, in fact Cu concentration values in MEM are higher than mean concentration of world soils but below the mean concentration of metal-rich soils [3].…”

There is very little information on the cycling of heavy metals in natural savannas. Venezuelan flooded savannas are characterised by acid soils with redox conditions which might induce Zn and Cu solubilisation. In those flooded savannas a network of small dykes has been constructed to control floods. The biomass accretion after dyking and the abundance of clay particles in the vertisols, dominant in the overflow plains, might be responsible for an increase in nutrient uptake and immobilisation. Due to the redox and pH conditions prevailing during flooding, some questions arise on the fate of the heavy metals. Are they significantly lost as soluble and particulate forms, which in turn, can induce a potential risk of microelement deficiency? Or, on the contrary, are heavy metal inputs in precipitation waters retained somewhere in the terrestrial pools of the watershed allowing for an adequate micronutrient economy? By using inputoutput budgets, which consider the total atmospheric input and total output in stream runoff (soluble and particulate) for zinc and copper we concluded that in Mantecal flooded savannas, a net accumulation of micronutrient in soils is actually occurring through organic and inorganic complexes, a process that is counterbalanced by the losses of particulates through erosion.

“…In addition, Wong et al (2007) concluded that dissolved organic matter interacts with the clay minerals becoming less accessible to microorganisms. Due to its higher stability against microorganism degradation, the SOM of the clay fraction could have a stabilization effect on the metals and reduce their bioavailability (Dabkowska-Naskret, 2003).…”

. Interactions between metals and soil organic matter in various particle size fractions of soil contaminated with waste water. Geoderma, Elsevier, 2009Elsevier, , vol. 1, pp. 217-223. 10.1016Elsevier, /j.geoderma.2008 Open Archive TOULOUSE Archive Ouverte (OATAO) OATAO is an open access repository that collects the work of Toulouse researchers and makes it freely available over the web where possible. Only scarce field studies concern the consequences of natural soil organic matter (SOM) and metal interactions on SOM dynamics in soils. We investigated the interactions of four metals (Pb, Zn, Cu and Cd) with the SOM associated to five different size fractions (between 2000 µm and b2 µm) of a sandy top soil contaminated by waste water. Metal, organic carbon and nitrogen concentrations were measured and chemical extractions (with Na 4 P 2 O 7 and EDTA) were also performed to assess the variations of SOM-metal interactions irrespective of the size fraction. In addition, as in that selected contaminated site, maize (C 4 plant), replaced C 3 crops 15 years ago, natural isotopic 13 C labelling gave new insights into SOM turnover. First, the results suggest that metals influence the SOM dynamics in that sandy soil: a C 3 "old carbon" enrichment was observed in the small or clay size fractions, while the "new" C 4 carbon associated with sandy soil particles presents a rapid turnover. Metal accumulation in the clay fraction is attributed to particulate organic matter (poorly associated) and SOM decay which overtime accumulated metals and eventually these metal-SOM associations prevent the biological decomposition of such carbon pools. Moreover, the δ 13 C signals, C/N ratios and results from chemical extractions clearly showed differences in the origin, nature and reactivity of the SOM as a function of the size fraction with consequences on the metal behaviour. Differences were observed between metals studied: Zn seems to be mainly bound to SOM associated with clay particles, while Pb seems to prefer to interact directly with the mineral surfaces versus the SOM.

“…Soils in many areas of Poland are characterized by low contents of organic matter (OM), which greatly contributes to their limited fertility and productivity, and higher vulnerability to contamination and degradation (Dabkowska-Naskret, 2003;Maciejewska et al, 1998). Soil degradation observed in some areas is so relevant that it causes a dramatic need to improve the soil structure and the contents of soil organic matter (SOM).…”
