“…The effect of soil type on sustainable production of crops confirms the results of many studies (Kunzová and Hejcman 2009, Černý et al 2010, Hejcman et al 2012). The highest increase of nitrogen content in grain was achieved at S1 by N treatment (10% higher than control) and at S2 by N + ST (26% higher than control) and by uptake of nitrogen at both sites by N + ST. Use of fertilizers with nitrogen in mineral form at S2 site led to significantly higher content of nitrogen in grain and straw compared to unfertilized treatment, which is in agreement with many researchers (Pettersson and Eckersten 2007, Sedlář et al 2011, Hejcman et al 2013. Previous application of organic fertilizers resulted in lower or comparable value of nitrogen content to unfertilized treatment.…”

The aim of this study was to evaluate nitrogen (N) efficiency from different organic and mineral fertilizers applied to the spring barley. Dry matter yield, N content and N uptake of spring barley from 16 years of experiments at two sites in the Czech Republic with different soil and climatic conditions were analyzed. For assessing of nitrogen efficiency nitrogen utilization efficiency (NUtE, kg/kg), recovery efficiency of applied N (%), agronomic efficiency of applied N (kg/kg) and summary N balances (ΣΔN, kg/ha) were observed. Six fertilization treatments were utilized: no fertilization (control); sewage sludge; farmyard manure (FYM); N in mineral fertilizers (N); NPK in mineral fertilizers (NPK) and N in mineral fertilizers + straw (N + ST). Yields were about 68% higher at NPK (S1 site) and 55% at N + ST (S2 site) in comparison with control. The highest NUtE was recorded at both locations after application of FYM. Higher NUtE from mineral fertilizers was obtained at low productive S1 site. At both sites a trend of decreasing ΣΔN over time was observed. At both sites a trend of decreasing negative N balance was observed. At lower productive site the decline of N balance was minimized for mineral fertilizers treatments in last experimental years. At higher productive site the differences between treatments with mineral nitrogen and control were lower and the decline of N balance continued over all 16 years of experiment duration.

“…The same tendency was reported by Sedlář et al (2011) at CULTAN-fertilized spring barley. In 2010 at all sites a clear tendency to lower yields at CULTAN treatments was observed (Table 7).…”

In field experiments over three vegetation periods (2010)(2011)(2012) we studied impact of the CULTAN (controlled uptake long term ammonium nutrition) method on yield and yield parameters of kernel maize. The field experiments were conducted at three sites with different soil-climatic conditions. CULTAN treatments were fertilized once with the total amount of nitrogen using an injection machine (at the canopy height of 20 cm) and compared to conventional fertilization with calcium ammonium nitrate application at pre-sowing preparations. In all treatments the amount of nitrogen was the same, 140 kg N/ha. In 2010 at Humpolec site, CULTAN urea ammonium nitrate + inhibitor of nitrification treatment gave by 20.5% higher number of ears compared to CULTAN urea ammonium nitrate treatment. In 2011 at Ivanovice all CULTAN treatments reached statistically significantly higher number of kernels per ear. The higher 1000 kernel weight at CULTAN treatments was observed in 2012 at the Ivanovice site; a statistically significant difference between conventional and CULTAN urea ammonium nitrate + inhibitor of nitrification treatment was observed. Fertilization of maize with nitrogen using the CULTAN method under the conditions of the Czech Republic provides the same yield certainty as the conventional surface application and the CULTAN method of fertilization increases the yield certainty at delayed sowing. Harvest index was statistically significantly influenced by year, fertilization treatment and site.

“…The relatively high yield in the control without any fertilizer input in 2010 was consistent with high yields in the controls of other field strips in the RFE in other years (5.0, 5.5 and 3.9 t/ha in 2008, 2009 and 2011, respectively), indicating the high suitability of the study site for barley production. The high suitability of the study site for barley production is also illustrated by grain yields over 9 t/ha recorded in the N 4 P 2 K 2 and FMN 4 P 2 K 2 treatments, which are very high in comparison with maximal grain yields from different experiments in the Czech Republic -5.2 t/ha by Černý et al (2010), 6.8 t/ha by Hřivna et al (2009), 7.2 t/ha by Koutná et al (2003) and 8.8 t/ha by Sedlář et al (2011). The reduced grain yield in PLN 4 P 2 K 2 compared to the N 4 P 2 K 2 and FMN 4 P 2 K 2 treatments was probably due to adverse effects on barley growth from the high nutrient application in this treatment.…”

Little attention has been paid to the effect of long-term fertilizer application on concentrations of elements in grain of barley produced on the metal non-contaminated agricultural soil. In 2010, we analyzed yield and concentrations of elements in grain of spring barley in unfertilized control, mineral fertilizer application (N 4 P 2 K 2 -70, 60 and 100 kg N, P and K per ha) and combinations of farmyard manure or poultry litter with mineral fertilizer (FMN 4 P 2 K 2 and PLN 4 P 2 K 2 ) treatments in the Ruzyně Fertilizer Experiment established on Luvisol in 1955 in Prague (Czech Republic). The yield of grain ranged from 4.03 to 9.74 t/ha in the control and FMN 4 P 2 K 2 treatment. There was a positive effect of fertilizer application on concentrations of nitrogen, phosphorus and potassium, but no effect on concentrations of calcium and magnesium. With the exception of iron, concentrations of micro (copper and zinc) and risk elements (arsenic, cadmium, chromium, lead, manganese and nickel) were not significantly affected by the fertilizer treatments. Long-term use of organic and mineral fertilizers with appropriate application rates does not represent any risk for contamination of barley grain by risk elements on mineral rich and metal non-contaminated agricultural soils.
