Concentration of trace elements in arable soil after long-term application of organic and inorganic fertilizers

Abstract

The Ruzyně Fertilizer Experiment (RFE, the Czech Republic) was established on a permanent arable field (illimerized Luvisol) in 1955. The effects of long-term application of several organic fertilizers (dung water, farmyard manure, poultry litter) and mineral N, P and K fertilizers on plant-available (extracted by CaCl 2 ), easily mobilizable (extracted by EDTA), potentially mobilizable (extracted by HNO 3 ) and total concentrations of trace elements were investigated in 2008. Concentrations of all analyzed trace elements in the applied fertilizers did not exceed the limits permitted by Czech national legislation. Concentrations of As, Cd and Cr were highest in single superphosphate, those of Cu, Mn and Ni were highest in poultry litter and those of Pb and Zn were highest in dung water. Poultry litter had the second highest concentration of As and Zn. Poultry litter supplied the soils with considerable amounts of Cu,

Effect of long-term fertilizer application on yield and concentrations of elements (N, P, K, Ca, Mg, As, Cd, Cu, Cr, Fe, Mn, Ni, Pb, Zn) in grain of spring barley

“…In our study, Cd concentrations were substantially lower than concentrations recorded by other authors on Cd contaminated soils: 0.12-0.7 mg/kg by Dudka et al (1996), 0.24 mg/kg by Sękara et al (2005) and 0.05-0.12 mg/kg by Kaniuczak et al (2011). Low Cd concentrations in our experiment were because of the almost neutral soil reaction resulting in low Cd availability and low application rate of Cd by fertilizers (Uprety et al 2009). We recorded low Cd concentrations in grain despite the total concentration of Cd in the soil exceeding the Czech limit.…”

“…A trend toward lower concentrations of Cr in treatments with application of organic fertilizers was recorded despite total concentrations of Cr in the arable layer being the same in all treatments (Uprety et al 2009). The increased availability of Fe due to the lower soil pH, together with the higher availability of P in the PLN 4 P 2 K 2 and FMN 4 P 2 K 2 treatments than in the control and N 4 P 2 K 2 treatments, probably decreased Cr uptake, because Fe and P can act as Cr antagonists (Wallace et al 1976).…”

“…Although poultry litter supplied the soil with considerable amounts of Cu, Mn and Zn (Uprety et al 2009), there was no effect of fertilizer treatment on concentrations of these elements in the grain. This can be explained by a dilution effect and by the low ability of barley to accumulate Cu (Belyaeva et al 2005).…”

Copper and zinc forms in soil fertilized with pig slurry in the bean crop

“…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…”
