“…For comparison, we added 6-10 t lime ha −1 and 87 kg P (i.e., 200 kg P 2 O 5 ) ha −1 . In our study Olsen P seems to predict satisfactorily plant P concentrations (correlation analysis when all treatments were included, achieved R 2 = 0.718, significant at P < 0.01), which agrees with Németh et al (2002). There is a difference, however, between Olsen P and plant P; that is, P in plant did not increase at L1P1 compared to L0P1, whereas in Olsen P, L1P1 and L0P1 did have significant differences in soils B, C, and E. In other words, irrespective of soil pH status (either acidic or neutral), our test plant P levels were similar in P-added soils in both pH values, while at the same time soil extractable P increased when P-added soils were limed.…”

Acidic soils typically suffer from high phosphorus (P) retention, a problem that can be dealt with using greater P fertilization, soil liming, or both. The aim of this work was to examine which of these practices bears the more beneficial result for Lolium perenne L. growth. In a pot experiment, five acidic soils were treated as follows: L0P0 (unamended control), L1P0 (liming only), L0P1 (P addition only), and L1P1 (both liming and P addition). We found that P amendment alone was sufficient to increase plant P levels when the initial soil P concentrations were low. Liming without P addition increased plant P satisfactorily only in the high-P soil. We conclude that P addition alone is a better practice than liming alone for improved plant growth conditions in acidic, low-P soils, unless there is relatively high P content in soil, in which case liming alone may be sufficient to increase P availability.

“…Similarly, the concentration of Cr in superphosphate was below the permitted limit in fertilizer (150 mg of Cr kg -1 of P). The highest concentration of Cd in superphosphate from all applied fertilizers is consistent with previously published results, showing that P fertilizers are the major source of Cd in agroecosystems (Németh et al 2002;Otero et al 2005;Cesur and Kartal 2007;Chen et al 2007). Concentrations of trace elements in organic fertilizers also did not exceed Czech limits, which are 10, 2, 100, 100, 50, 100 and 400 mg of As, Cd, Cr, Cu, Ni, Pb and Zn kg -1 of dry matter, respectively (Budňáková et al 2004).…”

“…The presence of trace elements in fertilizers implies that their long-term application has the potential to induce soil contamination (Németh et al 2002;Chen et al 2007;Otero et al 2005). Many mineral P fertilizers possess considerable amounts of trace elements, especially in those fertilizers that are produced from North African phosphates (Oyedelel et al 2006;Malak and Emad 2007;Ramadan and Ashkar 2007).…”

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,

“…Cadmium is of special interest because of its significant concentration in many P fertilisers which, if permanently applied, induce Cd accumulation in soils and an increase in the concentration in plant biomass (Mortvedt 1996;Gray et al 1999;Taylor and Percival 2001;Németh et al 2002;Salviano et al 2006;Chen et al 2007). …”

The Rengen Grassland Experiment (RGE) was established in the Eifel Mts. (Germany) on a low productive Nardetum in 1941. Since then, the following fertiliser treatments have been applied along with a two cut system: unfertilised control, Ca, CaN, CaNP, CaNP-KCl and CaNP-K 2 SO 4 with basic slag (syn. Thomas phosphate) as the only P fertiliser. The effect of long-term fertilisation on plant-available (extracted with 0.01 mol l -1 CaCl 2 ), easilymobilisable (extracted with 0.05 mol l -1 EDTA), potentially-mobilisable (extracted with 2 mol l -1 HNO 3 ) and total concentrations of trace elements (As, Cd, Cr, Cu, Fe, Mn, Ni, Pb and Zn) in the top 0-10 and 10-20 cm of soil were investigated in 2006. According to redundancy analysis (RDA), the effect of treatment on the concentrations of risk elements was significant and explained 82.3 and 90.6% of the variability in the data in the 0-10 and 10-20 cm soil layers, respectively. Basic slag supplied the soil with considerable amounts of As, Cr, Cu, Fe, Mn and Zn. Following 65 years of fertiliser application the concentrations of risk elements in the soil profile had increased substantially, especially with basic slag. However, threshold limits for total trace element concentration in soil permitted by Czech national legislation were exceeded only in the case of As. The increase in plant-available As concentrations was most critical as it increased the potential uptake of As by plants in plots fertilised with P. Although P treatments received more than 300 g of Cr ha -1 annually, no effect on plant-available Cr soil content was detected. This contrasted with the accumulation of total Cr in the 0-10 and 10-20 cm soil layers. Furthermore, plant availability of Cd, Fe, Mn and Zn was affected by soil pH and generally decreased with the application of quick lime. Plant availability of these elements was not correlated with amounts supplied by fertilisers.
