“…For this fraction, there was an increasing quadratic response, with highest Zn content at the highest dose in both treatments. Unlike Cu in the soil, Zn is more weakly bound to clay minerals and adsorbents in the form of oxides, hydroxides and oxyhydroxides in the soil, making this metal more labile and bioavailable (Sipos et al, 2008;Paradelo et al, 2011;Mallmann et al, 2012), which explains the higher presence of this element in the soluble and exchangeable fractions of the soil.…”

“…The low contents in this fraction may have occurred because the applied doses were not sufficient to occupy all bonding sites in the soil and allow the increase in the soluble fraction. The content of Cu in the free form is extremely low due to its affinity with organic and mineral compounds of the soil (Sipos et al, 2008;Muñoz et al, 2008).…”

“…The lower intensity of bonding force of Zn to soil colloids, compared with Cu (Sipos et al, 2008;Uprety et al, 2009), allows the mineral fertilizer to promote greater availability, a condition that occurred in the three forms of Zn in the soil Table 2. Copper (Cu) contents in shoots and roots of bean plants in response to the application of different doses of this element in the soil in the forms of mineral oxide or pig slurry…”

“…This fraction is considered as inert and is not extracted in the other steps of the fractionation, but is considered as a chemically stable and biologically inactive fraction (Sipos et al, 2008;Souza et al, 2012).…”

“…In order to increase the efficiency of use of this fertilizer, it is necessary to know the dynamics of these metals in the soil, because they are results of interactions, such as: pH, organic matter (OM), composition of clays, redox potential, competition in the adsorption sites, complexation with OM, temperature, microbial activity and the tendency to form precipitates and coprecipitates (Kumpiene et al, 2007;Sipos et al, 2008).…”

The application of pig slurry may have different influence on copper (Cu) and zinc (Zn) dynamics in the soil compared with mineral fertilization. The aim of this research was to determine the different forms of Cu and Zn in soil and their uptake by bean plants in response to the application of mineral fertilizer and pig slurry (PS). The treatments were: mineral fertilizer (Cu and Zn oxides) and liquid pig slurry, at increasing rates (0/0, 1.7/6.0, 3.4/12.0 and 6.8/24.0 kg ha-1 Cu/Zn, respectively) applied in a Rhodic Kandiudox. PS increased the Cu content in soil in the exchangeable form, Fe oxides and residual, while the mineral fertilizer increased Cu contents in the fraction associated with soil organic matter. Soil Zn contents in the fractions available, exchangeable and SOM were highest under mineral fertilization, while in the soluble fraction the contents were highest under PS. The fertilizers had not impact on Cu and Zn contents associated with Al oxides, and these elements were mostly associated with Fe oxides in the soil. PS promoted the highest biomass production in shoots and roots of the bean plants, reflecting in the highest accumulation of Cu and Zn.
