“…In multi-annual field experiments conducted by Lehoczky et al [8], the effect of long-term application of NPK fertilizers on the availability of certain trace elements by plants in the soil was relatively insignificant, with phosphorus fertilizers having a stronger effect than nitrogen and potassium fertilizers. The strongest effect was noted for molybdenum following the application of phosphorus fertilizers.…”

“…Even when elements which are useful (for plants) are found in the soil in excessive amounts, they are moved along the subsequent chains of the trophic chain, and, in extreme cases, may even have a negative effect on the growth and development of plants and other living organisms [6,7]. The application of mineral fertilizers in doses recommended for crop cultivation is not expected to result in an excessive uptake of trace elements by plants [3,8].…”

The aim of the study was to determine the effect of increasing potassium fertilization (0, 140, 190, and 240 mg K2O/kg of soil) in the interaction with nitrogen fertilization (130 and 170 mg N/kg of soil) on the trace elements content in the typical, non-contaminated agricultural soil. The trace elements content in the soil depended on nitrogen and potassium fertilization. Potassium fertilization had a more significant effect on trace elements content in the soil fertilized at the same time with a lower nitrogen dose (130 mg N/kg soil). Increasing potassium fertilization increased the content of cadmium by 83% and lead by 32% and reduced the amounts of chromium by 10% and iron by 3% in the soil, particularly in the series with a lower nitrogen dose (130 mg N/kg soil). The effect of potassium fertilization on the content of other trace elements was less unambiguous since, for most of trace elements, lower doses of this fertilizer contributed to growth of trace element, while higher doses lead to a decrease in their accumulation in the soil. Nitrogen fertilization increased the contents of zinc and iron—3%, copper—9%, manganese—12%, chromium—15%, and cobalt—59%, while reducing the contents of cadmium and nickel—24% and lead—45%. Permissible standards for trace elements content in the soil have not been exceeded.

“…Contamination of soil with trace elements (mainly heavy metals = risk elements) represents a serious risk for crop production, food quality and human health because of their high toxicity and bioaccumulation, high persistency in the environment and relatively high mobility (Mench 1998;Lehoczky et al 2005;Lavado et al 2007). While naturally occurring in the environment, risk elements may be introduced into agricultural soils, especially by anthropogenic activities.…”

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.

“…For example, Shuman (1988) showed that increasing inorganic P application increased DTPA-extractable Cu, Zn, Fe, and Mn. Conversely, Lehoczky et al (2005) studied the effects of long-term mineral fertilization on micronutrient availability and found that increasing P fertilizer rates increased plant available Mo (as defined by KCl + EDTA-soluble), decreased plant available B, and had no effect on Mn and Zn concentrations. Li et al (2007) reported long-term application of superphosphate did not increase DTPA-extractable Cu, Zn, and Mn, but increased DTPA-extractable Fe.…”

Micronucrient availability is important to crop production and can be affected by long-term application of P and organic amendments. This study was condutted to determine the effects ofthe long-term application of different sources and rates of P application on extracrable [DTPA-sorbitol (diethylenetriamine-pentaacetic acid and sorbitol] micronutrients. Soil extractable and total micronutrients (B, Cu, Fe, Mn, Mo, and Zn), pH, and organic matter content were determined from sites across Oklahoma that had received long-term applications of beet manure, swine effluent, biosolids, or commercial fertilizer. Three continuous inorganic P experiments diat had been conducted for 36 to 39 yr and three organic P experiments diat had been conducted for 11 to 12 yr were evaluated. Tlie long-term application of inorganic P had litde effect on micronutrient availability. However, long-term application of biosolids significandy {p < 0.05) increased extractable Cu, Fe, Mo, and Zn in soil, while long-term application of beef manure significandy increased all die micronutrients evaluated. Similarly, the long-term application of swine effluent significantly increased extractable B, Cu. Mo, and Zn in soil. The addition of micronutrients from organic amendments increased micronutrient availability, while long-term inorganic P application had litde effect. The result of our study indicates organic amendments make an ideal fertilizer source for areas with micronutrient deficiencies.Abbreviations: DTPA, diethylenetriamine-pentaacetic acid; EDTA, ethylenediamine-tctraacetic acid; ICP-AES, inductively coupled plasma atomic emission spectroscopy; SOM, soil organic matter; TSP, triple superphosphate.
