“…The same outcome was reported for Cu and Zn concentrations in maize following the addition of liquid swine manure (Berenguer et al 2008) and liquid dairy cattle manure (Nikoli et al 2011). Essentially, plant appeared to be capable of restricting heavy metal translocation from soil to roots and internal transport to avoid excessive heavy metal-induced damage (Ahumada et al 2009). It was also suggested that increasing yields have resulted in decreased concentrations of trace elements in produce because of a 'dilution effect' caused by plant growth rates exceeding the ability of plants to acquire these elements (Jarrell and Beverly 1981).…”

Fertilization of crops with pig manure is a common practice throughout the world. Nevertheless, due to the relatively high copper (Cu) and zinc (Zn) contents in pig manure, continuous application of pig manure could have negative effects on soil and plant. The study aimed at the impacts of long-term applying different pig manure rates (equivalently 0, 100, 250 and 500 kg total N/ha/year from 2002 to 2008 and 0, 10, 25 and 50 t fresh weight/ha/year from 2009 to 2011, respectively) on Cu and Zn accumulation in soil and plant. During the 10 years of the experiment, a total of 2.04 to 10.20 kg/ha/year for Cu, 3.15 to 15.73 kg/ha/year for Zn were applied to the soil. Results from this study showed that long-term pig manure application resulted in serious accumulation of Cu and Zn in soil, total Cu and Zn concentrations increased by 204% and 107% at high application rates, respectively. Although topsoil Cu and Zn concentrations were below concentrations considered phytotoxic to crops, according to current Chinese legislation, it would take only less time than 16 and 27 years of high application rates to reach the allowable limits. Our result also suggested that Cu and Zn leaching occurred in the tested soil. The Cu and Zn concentrations in stalks and grains were not affected by the application of pig manure, and these values were lower than the threshold values for animal and human ingestion.

“…The majority of papers define the bioavailable/mobile pool as the most easily extracted fraction or labile fraction (Bacon and Davison 2008). The exchangeable and carbonate metal forms corresponding to the first step of BCR procedure are considered readily mobile and available to plants, while metals incorporated in clay crystalline lattices are relatively inert (Walter et al 2006;Ahumada et al 2009). A good correlation has been observed between the labile fraction determined by sequential extraction and Cu and Zn content in plant of Ryegrass and subterranean clover (Trifolium subterraneum; Ahumada et al 2009).…”

However, Torri and Lavado (2009) concluded that the most available fractions obtained by soil sequential extraction did not provide the best indicator of Cu and Zn availability to Lolium perenne.…”

This study assessed the effect of biosolids applied at rates, 0, 30, 45, and 60 Mg ha −1 on the chemical associations and bioavailability of Cu and Zn in soils from an important agricultural zone of the Metropolitan Region in Central Chile. Three methods were used to determine the bioavailability of Cu and Zn in soils: ryegrass (Lolium perenne) plants, diffusive gradients in thin films (DGT) technique, and Community Bureau of Reference (BCR) sequential extraction. The DGT effective concentration (C E ) and sequential extract acid soluble fraction of the BCR extraction (most labile fraction of the soils, normally associated with bioavailability) were compared with total metal concentration in ryegrass plants as a means to compare the chemical and biological measures of bioavailability. Total Zn was higher in comparison to Cu for all treatments. Concentrations were within the limits set by the Chilean regulations for land-applied biosolids. Metals in the control soil were primarily found in the residual fraction of soils. Biosolids application generally decreased this fraction, with a subsequent increase observed mainly in the acid soluble fraction. The contents of Cu and Zn in ryegrass plants increased with increasing rates of biosolids. Comparison of the Cu and Zn content in ryegrass plants with C E , showed a good correlation for Zn. However, the C E for soil Cu was only related to plant Cu for some of the soils studied. Correlation between Zn in ryegrass plants and the labile fraction of Zn as measured by the sequential extraction was excellent, with correlation coefficients >0.9, while for Cu, correlation coefficients were lower.

“…Most published values exceed the warning and critical legislative limits (50 and 140 mg kg À1 , respectively) established in the EU for Cu concentrations in agricultural soils (Komárek et al, 2010). These data indicate that potential soil contamination could occur through the use of copperbased fungicides, although data on Cu mobility in soils and its availability to biota are also necessary for the assessment of its environmental impact (Ahumada et al, 2009;Brun et al, 1998;Flores-Vélez et al, 1996).…”
